I have no idea why anyone would pay more than you would pay for this set. I had this exact set for years, it cuts very smooth bottom dados. I really like the full size chippers, and I’ve always been able to get the exact width that I need. I really don’t know why anyone would pay $100 more or $150 more just to cut smooth dados, I’m not thinking that the carbide tip blades in the $250 sets are going to last one minute longer than the carbide tips in this set. Due to circumstances beyond my control, I had to buy a new set, I did look around before purchasing this brand, and found no reason to buy anything different. Get it and you’ll be happy with it.

I love Festool, I buy their sanding pads for my rotex 150, I think you can't beat their quality products. I have to admit, forking out $125 for a replacement blade from Festool seemed steep. Went for this blade instead and let me tell you, this blade cuts just as good as the festool one, can't tell the difference, go for it. P.S: I cut wood only, not sure, if that's the case for other materials. Really glad I found this on Amazon.

OK, this blade is a Chinese knockoff of the Freud LU80. It has a high atb grind on the teeth, which means it will cut veneered plywood without tearing the veneer. Very handy if you have to cut up a bunch of nice plywood for cabinets, etc. I have owned the Freud LU80 and was very impressed with the quality of the cut. Hi atb teeth are very fragile though (like little knives), and my Freud blade was destroyed when I accidentally cut through a small nail. I thought I'd take a gamble on an inexpensive replacement with the same tooth profile, thinking that it should cut the same. Sure enough it does, and for darn near half the price. I can't distinguish any difference between the cut on this blade and the Freud's. Nice work on Oshlun's part.

BTW, although it doesn't say on the description, this is a full kerf blade.

We have a need to cut through 1/4 inch thick x 8 inch fiberglass. Previously we've used a band saw which is very tedious and difficult to keep to a straight line. We bought this blade to put in our chop saw. It's worked perfectly. We can slice cleanly through the fiberglass sheet in just a few seconds. Obviously it throws out a whole lot more dust than a band saw so protective masks and good ventilation are important.

I installed this blade in my Milwaukee abrasive chop saw. I carefully looked at the blade speed and determined this would match up. This blade makes perfect, clean cuts in extruded aluminum (80/20 type material). The only drawback i see when using this in an abrasive saw is the time to get the blade up to speed and slow down after cuts. Be careful. Use plenty of blade lubricant as well.

Cuts great and great durability. Cut 3/16 plate smooth and easily. Compared to the original yellow brand I would say close to equal and good longevity. I use this saw alot so blades are important.

If this saw blade cuts steel like my Oshlun aluminum cutting blade cuts aluminum, it will also be a winner. I haven't gotten to use it yet, but when I am through with a rush project I am currently working on, I will try it out on some steel shapes that I have in the garage. The unique tooth configuration should allow my 18 volt Firestorm Laser saw to cut steel effortlessly, and with carbide teeth it should last a long time. Stay tuned....

While i was worried that i would not be satisfied by these less expensive blades, i have been happily surprised. They are a great alternative to spending top dollar for Festool blades that are frankly a bit overpriced. I'd love to see the actual cost compared to mark-up on saw blades. Using a sharp blade saves time, improves quality and pleasure of work imensly. The option of Oshlun blades is a wonderful thing about capitalism, which usually is not so nice. While i might not use them on every job, 90% of the time they do a fine job and I see no difference (besides price) from the Festool blades. Recently I used a not new 48T Oshlun blade while ripping "Hardy Plank" I did a good 10 8 foot rips of the silica concrete board. I think the blade is toast, but even during the final rip it performed more than adaquately. I continue to be impressed and pleased with these blades. I'm lookin forward to see how they sharpen, just for kicks, I'ts probabaly cheaper to toss them, but my sharpening service does a great job, so it will be a worthwhile experiment.

I bought this blade not knowing what to expect, as I have never cut metal with this type of blade. I only needed to make about 50 cuts in extruded aluminum I-beam, so if it could complete that job, I would be happy. So far it has performed flawlessly. I even used it to cut some 1/2" EMT, though not recommended, it did the job. I may have shortened its useful life, but I cannot see how the quality of cut has been affected. I do recommend two things: First, use a wax cutting lube, and apply it every 5 or so cuts. Secondly, go nice and slow. For the price, I definitely recommend this blade.

I can not see any difference between my Festool blade and that one. Smooth cut with nice glossy feel to it.

There are a few things out there that are better options than Festool Replacement ones, all of which come at a better value.

Examples include t
1) Splinter Guard tape from Makita for the tracks which are way cheaper and better.
2) Bosh 35mm hose for 30$ ish compared with the 36mm from Festool at ridiculous price.
3) MFT3 MDF top that you can do yourself from any 3/4 MDF sheet.

This is only a short term review as this blade has not seen a lot of use. It is installed in my DeWalt metal cutting saw. Cuts on aluminum tubing, flat bar, and angle are fairly clean and easy, leaving only small bits of scale on the tubing ends. I applied lubricating wax to the blade prior to using it and during the cutting process. There appears to be no aluminum residue build up after doing this.

I bought this blade for my Stihl TS 420 block saw. Although I'm sure the manufacturer would call it ill advised to say the least, I've shoved this blade into wood with embedded steel plates and bands, rocks, dirt, you name it. If your segmented concrete blade or disc shouldn't be used to cut it, then this is the answer. If you have a demo saw/block saw, this blade is the necessary third for a complete collection, for with all three there is virtually nothing you can not cut. Be forewarned, this blade is not for the meek. It is not like a chainsaw. It makes a chain and bar seem like kid stuff. Sawzall for pre-school girls. This will grab ahold of and rip apart virtually anything it comes in contact with, and isn't so forgiving like the discs and segmented concrete blades. With that said, it is way easier to use than you might expect. Look closely and you will see the carbide tips are set at a slightly negative angle, so it doesn't rip the saw out of your hands as easily as you might expect. DEFINITELY have the full blade guard properly installed and angled to protect from the shrapnel, and be wearing proper leg, hand and eye protection because this thing removes serious chunks of whatever is unfortunate enough to come in contact with it. I've put alot of miles on mine already, and it is fine. I can tell it isn't as fast as it was new, but for what i've done to it, it is impressive. I highly recommend this blade for commercial applications by qualified operators. You will not be disappointed. I would caution DIY folks to be sure you are competent to safely operate such an aggressive machine and blade combination, and that such an extreme setup is necessary. It is neat, and it is kinda fun, but definitely not a toy.

I admit...I haven't used this yet. I bought it based on reviews from several woodworking friends and decided on this set rather than cheaper dado versions. I've been a woodworker for decades and used the old wobble dado version by Craftsman and wanted something that was easier to fine tune the width. This has it! The blades are plenty substantial, very heavy, with a variety of thinner spacers to fine tune the dado width. I'm looking forward to using this and can tell it's going to be perfect for my dado needs.

Great price and good product, As a contractor these do not last long. Everyday usage cutting nails, copper, gyroc and wood. But the blades do the job needed.

Buzzes right through 1/4 mild steel bar. I've made dozens of cuts and I can't detect any dulling. It does make a mess. Really sharp chips widely scattered. I built a quick sled for my cordless saw. Keeps the cut square and really contains the chips. It probably also keeps the tips from catching in the cut and breaking. Hard to believe it's this quick to cut steel with a saw I already have.

I bought this blade with the intent of using it when I refinish my hardwood floors. I figured a $20 blade would be a lot easier to swallow if I hit something hard while cutting out some of the old damaged boards.

I did some test cuts on 3/4" birch plywood scraps. The cuts were clean and sharp. To be honest, I'm not sure that the festool blade could have done any better. Maybe the Festool blade would outperform this blade on other materials but for sheet goods I would consider them equal.

I'll be ordering a couple more blades. At this price I would be crazy if I didn't.

Quite impressed with the quality, durability, and value of this blade. I only used it to cut up to 2" x 2" square aluminum tubing and am pleased. It still seems to cut fine after dozens of cuts. That said I highly recommend this blade

Listen up guys. I was looking for a blade that would cut aluminum profiles and work on a Dewalt chop saw running at 2800RPM so I emailed the manufacturer and got an immediate positive reply about this blade. LOOK NO FURTHER. This blade cuts aluminium clean and fast. No Burrs.
Buy this with your eyes closed but make sure they are open when using it.

Makes a clean cut on Glu Laminated Beams. Even cuts well at long angles. Got almost 100 cuts out of the blade on 5 1/8 deep glue laminated beams before signs of dulling showed. Would recommend this to anyone cutting large glue laminated beams or timbers.

I bought this for my Evolution R210 CMS saw. I only use this saw for cutting metal. Used this blade to make some cuts in mild steel. It cuts the steel like butter with very few sparks. It's much better the Eolutions original blade. I can recommend this blade for sure. Due to shipping and import taxes this blade is twice it's original price but still cheaper then an Evolution Steel blade (blue series).

This thing is the tops for me. For under $90, you can get this thing and get WONDERFUL dado cuts for your projects. I use it for box joints often! Make sure to TEST it on some pieces, get good at it a few times. Use the shims to get finer adjustments (because not all saw rulers are created equal). The dado might be set to 5/8" and you move the ruler over 5/8" and you may be 1/32 or 1/16 of an inch too big. Sadly, this can affect your box joints and dadoes. Still, it comes with the shims, so I just put in a few of them to widen the blade a little bit, just barely, and it turns out perfect every time! Once you get it tuned up, this thing will be your friend for life.

Be mindful of how long the arbor is on your table saw...some table saws only have an arbor that is 5/8
or 11/16" long, so all of these blades will not fit on the arbor safely! The box that this thing comes in is awful! I wish it had a nice carrying case made of rubber or plastic.

Still...works great. looks great, easy to learn how to use if you've never done it before, and great if you want to make cuts that are 1/4" thick all the way up to almost an inch thick. I use the 3/4", 5/8", and 1/2" setups ALL the time because those are pretty standard lumber sizes. Just go to the hardware store and get your choice thickness, and you can make all kinds of cool stuff once the blade and wood are the same width. Think about it...BUY THIS THING!

I have the Makita XSC04Z 18V LXT Lithium-Ion Brushless Cordless 5-7/8" Metal Cutting Saw. This 5 3/8 blade's cut-depth is more than adequate for my needs. I've been doing 90 and 45-degree cuts (not bevels) through 3 x 3 x 3/8 inch angle iron. So far, about 5 ft of cuts, and the blade is still working fine. This compares very well with the Makita blade that came with my saw - for half the price. I think this Oshlun blade cuts a little faster than the Makita. Definitely recommend.

This blade works very well. I use it all the time in my line of work. I cut mostly 3/8 all thread rod with it on my milwaukee 28v cordless saw. very handy when you need to shorten all thread rod when your up 20 feet off the floor and need to make a quick cut.

I use this in a small mitre saw and use it to cut mild steel. It cuts 1" x 1" mild steel bars very cleanly without all the sparks and burning that an abrasive wheel produces. If your mitre or cutoff saw is set correctly it cuts clean and straight.

Just remember to take the cut slow. Make contact with the metal slowly and don't use too much pressure feeding the saw into the cut. If you abuse the blade you might wear it out prematurely.

I was extremely skeptical about using my Festool track saw to cut aluminum sheets. I was afraid aluminum would somehow wreck the saw and the track. I was wrong it works great. Perfectly straight cuts with very little burring. It did no damage to my saw or track, not even to the sacrificial nylon strip on the track. I used this blade to cut up two 4X10 sheets of .125" aluminum without a problem. I did not notice a decrease in performance at any point and the blade still appears to be razor sharp. Although I cannot compare it directly to Festool's version my opinion is that it would probably hold hold up just as well while at a fraction of the price.

Great metal cutting blade. I use it with my Milwaukee M18 metal circular saw. Fits perfect, stays sharp for a while..

I bought this blade set to make Dados and Rabbets for a couple of small projects I do around the house. Since my saw's arbor is a little shorter, but more importantly, part of the metal sawdust collection port is close to the blade, it can't handle typical Dado stacks. This blade set, due to it's unique design, gets in there and also fits within the stock choke plate! You have to wiggle the two blades as you install going one at a time, but since they mesh together on the arbor, it's rather easy.

NOTE: Both of these blades are easily twice as thick each as typical blades, so they're noticeably heavier. I was concerned the extra weight would cause issues with the motor or cutting in general, but nothing seems to be amiss. I do give the motor an extra couple of seconds to get up to speed before pushing through any material.

The two sizes this blade set cuts (1/4" and 3/8") are accurate and VERY clean. These are the perfect sizes to create box drawers from either 1/2" or 3/4" sheet goods, which is what I plan to in the near future, using either the "Quarter, Quarter, Quarter" method for 1/2" material, or "Half, Half, Half" for 3/4" material. Overall, I'm very pleased with this purchase.

Other blade replacements I have found have a kerf to thin to clear the Dewalt tracksaw's riving knife. This Oshlun blade's kerf is wide enough to clear the knife and the resulting cut is excellent. It could use a bit more rake (tooth angle) to make the cut a bit easier, but overal this blade is a good replacement.

I was looking for a bade to cut aluminum for a FIRST robotics team working out of my basement. My initial search through a well known industrial supplier showed blades like this starting at $250. That was pretty much a non-starter. I found this one on Amazon and read the reviews and decided to give it a try. It cuts cleanly, quietly, and quickly. We have been cutting parts for several weeks now and the blade shows no signs of dulling. It also works great on PVC pipe and wood (we used that for training purposes. I have done a lot of shop work over the years and I can say this is an excellent blade. I highly recommend this to anyone who is planning to cut aluminum on conventional shop equipment. I used this blade on a table saw.

I bought this blade to cut a hole in my work bench to install a tail vise. When I built the bench top years ago I foolishly used screws to join the slats together, so I knew it was a minefield. I didn't want to risk ruining my Festool blade, so I figured buying the less-expensive Oshlun blade was worth a shot. The Oshlun blade made a smooth, effortless cut in the wood bench top--almost as smooth as the Festool blade even though it's not advertised as a wood-cutting blade. I did hit a couple of the screws, and except for a few sparks, the blade went through them like they weren't there. I may never have to use this blade again, but this one use was worth the price I paid for it.

My dewalt track saw was wandering, after aligning the resharpened stock blade perfectly parallel, it was still binding in thick hardwoods. I’m glad I bought this blade instead of throwing my saw in the ocean, because it cuts better than ever. It’s a bit thicker than the stock blade which is a good thing, made a decent clean cut in 1-1/2” thick sycamore with zero burn marks.

With all those teeth is makes very smooth cuts. I'm working with red oak at the moment and this blade is doing exactly what I wanted it to do. The cross cuts are very good and I am very satisfied with the results. I've only had it for a couple weeks and so far it's not lost any teeth yet but I'll be keeping an eye on it.

I was hesitant to buy this blade since there were no reviews to vouch for its quality.I am a professional trim carpenter and needed a blade that could last and cut cleanly.I decided to take a chance rather than spend three times more $ on the festool brand or one of the other alternatives out there.I have been extremely impressed with this blade and have found the blade indistinguishable from the festool in use and in long life between sharpenings.I am buying a couple more since I like to have several blades on hand at all times.

Excellent tool. Mounted on a Chicago Electric, 6", cut off saw (9K rpm-no load). Cut through 1 1/4" x 1 1/2", 6061 aluminum bar stock with ease. With only mild pressure, the aluminum chafe flew. Gone in 30 seconds.

I used this in my 20v dewalt circular saw for cutting 26ga corrugated galvanized metal roofing (for raised garden beds). I ripped 2 panels at a time, lengthwise down the middle. Then i cut them across the corrugation and it did a beautiful job, and pretty quickly. I had to mount this blade on my saw with the label side in, so make sure you wear some goggles and gloves as the backward-pointing teeth will send sparks flying toward you.

A very good quality substitute at a much better price than the overpriced dremel blades that I was forced to use

Was looking at cut off saws to work some of my 1/8th aluminum stock and while researching came across this 10" non-ferrous blade. The idea of swapping the blade on my miter saw and having the convenience and accuracy of the tool appealed to me so I made the purchase. Couldn't be happier. The saw easily cut through all the aluminum I threw at it and produced exceptionally accurate smooth cuts each time. My miter saw isn't the greatest (Kobalt 10") but with this blade working non-ferrous metals was easy. For anyone doing this for the first time, recommend eye protection. The blade creates very fine metal flakes while working.

I have gotten about 50 cuts out of this blade so far. Most of them have been 45 degree cuts in 1x2x3/16" mild steel channel. It is now only starting to spark a bit, but still cutting straight lines.

Since I had to buy one for my obsolete 8" table saw, and loved it, I got one for a 7.5" blade circular saw! It cuts great!
I needed one for an old 8" table saw, and NOBODY stocks, or even sells- that size, I shopped around to all the hardware and hardware box/super stores, (you know the two I mean), and even Grainger could not get them!
When I went online, this was the only company that had 8" blades at a decent price, I found a couple others at 2 to 3 times the cost.
Both sizes are great blades, at a decent cost.

I was cutting 1:4 inch fiberglass panels and it performed very well cut as expected and was smooth. Checked after cutting and teeth was sharp

I have two sets of calipers: this one and a digital electronic caliper by iGaging that reads in fractions, decimals, and metric. If I really need to dial in a measurement precisely, I use the iGaging. But 98% of the time the Oshlun is my go-to! It's the one I carry with me in my pocket, my tool bag, or even when I go to the store and need to measure a board or a bolt. It's so much easier to intuit the dimension of an object when I'm seeing a visual representation of where that dimension lies on the fractional "clock face." So many times when I use the other one - the digitial one - it will give me an answer of, say, 21/64ths and then I have to stop and spend two minutes doing math in my head and figuring out what that precise number means in practical terms. As a woodworker, I technically work to the nearest 32nd, but I THINK in terms of 16ths and 16ths "strong" or "weak". The Oshlun gives me that knowledge at a glance, without mental math and without hesitation. A machinist may need an instrument that can give them accuracy to the thousands of an inch, but for the work I do, the Oshlun Fractional Dial Caliper is the perfect tool for measuring when I need something more precise than my tape measure, alone. Highly recommended.

Did an excellent job cutting my kitchen countertop to size. After about 40 linear feet, it became noticeably duller. Overall, very plesed I was able to accomplish the job with just my small circular saw. I think it would do equally well for other brand names like Corian.

This is an excellent dado set that produces a true flat bottom dado. The number of chipper blades and shims enable very precise measurements. They are as good as dado sets costing much more.

I own two other dado sets one being a Forest dado king and the other one is a Freud SD608 I am quite disappointed in the Forest set I have the Freud on a radial arm saw just to dado 2x4s for making shop carts. I had read some reviews on the Oshlun one stated that it was a bit tight to get on the arbor I own an older Delta cabinet saw and have no problems. The cuts in my opinion are amazing compared to my other sets and for the price you can't beat it. I especially love the full size chippers makes a world of difference. Thanks so much for a wonderful product.

Purchased to use in Wood! Why? The 1" bore.

To explain, we have a 12" "Original Saw Company" Radial arm saw in the shop. The 12" blades we have tend to be deafeningly loud, the outer rim speed is so high.
To combat this, we use 10" blades thus reducing the outer rim speed a good deal. This was easy to do with my old Delta R.A.S. that had the arbor more common in 10" blades ( 5/8" ) .
Since upgrading to the "Original" with the 1" Arbor (proper for 12" blades) I have had a very hard time finding any non custom made 10" blades with 1" arbor,.. until this one.
It makes very clean cross cuts in pine and hard woods. No tear out, super smooth.

And it is Soooooo quiet in the big R.A.S. we can no longer hear it over the dust collection.

This dado set was on my Christmas list - and Santa delivered! I researched quite a bit and narrowed it down the the entry level Orange, Freud, and the Oshlun. The Oshlun won out primarily due to the low price point. Many woodworking forums indicated the quality was comparable to the more costly competition. I'm not a tool snob and don't really care if my tools are made in Asia, Germany, or on the moon, as long as they last and function as intended. I've used the blade several times now, cutting 3/4 slots with and against the grain in softwood. So far I'm impressed. I haven't used the competition, so I can't comment on how it compares. I have a large saw with a powerful 240v motor, so I can't comment on how practical this dado would be in a small table saw.

Pros: High tooth count, decent manual, smooth cut, flat bottom (see note about edge scoring) and big chippers

Con: Box - many dados come in a box that doubles as a storage case, not this one. The cardboard and foam is adequate for shipping, but not suitable for storing.

Would I recommend this to a friend? Yes

Note: All dados claim to leave a flat bottom. That does not mean that the entire bottom of the cut is actually flat. It does mean that the bottom will be flat except for a fine score at each edge of the cut. Each edge of the cut will leave a very fine score line to minimize tear out. If the cut is just one pass, the bottom looks perfectly flat, the score lines are quite a non-issue and difficult to see. However, if used in multiple passes to remove larger amounts of material, such as in making tenons or larger slots, the outside edges of each cut will leave a fine line that is easily seen. Don't confuse "flat bottom" advertising to indicate a true flat bottom and smooth cut. A truly flat bottom cut would likely come with a bit of tear out. If you absolutely must have a true flat bottom, stick to a router.

Inherited a radial arm saw. Read the manual and watched the on line vids and got the hell scared out of me and almost put it to the curb as being far too dangerous to use. Turns out, there are specific blades for these saws which minimize the grab of the blade on the wood but are NOT the same blades for for your chop or table saw, even though at first glance they look the same. I initially balked at paying 4-5 times the price of one of those blades for this "right" one, but factored in how versatile the saw could be and the cost of a trip to the local emergency room should the saw sling back on me....and bought one. Smartest decision ive made all month. With the addition of a bushing on the arbor, the blade fit my radial arm saw great and the cuts are smooth. The negative camber design (what sets them apart from other, regular saw blades used on other saws) is what keeps the blade from being too aggressive- essentually keeping it from biting off more than it can chew, and skating up and over the board, or suddenly yanking the board (and potentionally parts of my body) through when ripping. Used this on plywood, mdf, ash and cedar so far, does what it should, I have my fingers and the blade is still sharp.

I've just installed it on my DeWalt DWS 782, so I can't speak to longevity. However, it works and the laser line is right on the money. Bonus points for including extra batteries. Also, the hardest part of installing it was the process I would normally have to follow for changing the blade on my saw. Lastly, make sure you tighten the bolt on the blade properly. I thought I tightened it enough without ham handing it, but once the blade brake turned on the blade broke most and kept spinning.

I bought this blade because of the you tube “project farm” review (Best review channel). Understand only rated for ~1500rpm but installed on chop saw at 3300rpm and cut Aluminum, Raw Hide (Dog), PVC, and wood. Too much risk to cut anything harder but no tooth chips yet. Please take care, where leather wielding apron, face/neck shield, heavy jeans… a carbide tooth coming off at that speed can ‘hurt’ 🙂

I use this in a Rage 3 saw by Evolution. Works very well. Cuts very similar to other TCT (dry cut cold saw) I have. I can't speak to longevity as I have only made a hand full of cuts so far, but overall it works exactly as expected. I think you'd be foolish to try to put this blade in a 5k rpm wood saw and think you're going to get nice cuts in steel. These blades are intended for steel saws that have blade RPMs in the 2k range. When you have this in the correct saw it will cut mild steel like butter.

Up to this point, I have only used friction and abrasive blades to cut steel. I was skeptical of a blade that looks just like your standard wood blade would work well and could last. But I have been very happy with the speed and smoothness of the cuts, and so far, the blade seems to have remained quite sharp. I've only cut about four 1/2" dia. bolts and a dozen or so 1/2" rebar, so it's still a little early to tell how long it will remain sharp. But it has saved me a lot of time and has kept the metal much cooler than with other blade types. I'm very happy with it so far.

I'm a big Festool fan. Well, I should say that I really like the Festool products that I currently own. I've owned a few green tools that....well.....sucked. The track saw is one of my favorites. Yeah, it's a little underpowered when cutting bevels but I rarely use it to make these cuts. One thing, IMO, that Festool doesn't do well is make blades. I've owned a couple of the Kapex saws and the blades provided are pretty sad. The fact that they provide a 60T blade with a $1400 miter saw is ridiculous. Do they really think someone is using this saw for something other than finish trim??? Sure it has a negative hook but still.... Back to the Oshlun blade. It cuts great. Super clean cross cuts and plenty fast when ripping 3/4 ply. I highly recommend this blade and will be purchasing another. I purchased the 80T for my Kapex and it's a great blade as well.

Much nicer cut on plywood than the factory blade. Kerf size seems to be exactly the same so the lasers do not need adjustment between this and the Festool blade. I just got it so time will tell about longevity but as far as I can see at this point, paying more than double for the Festool 80t doesn’t seem to be a wise choice.

I used to buy Endurance blades because they lasted the longest. They went up in price so I tried Oshlun. It works just as well or better and lasts as long. I can now buy 2 blades for what I used to spend on one. These types of blades don't last a long time anyway but they will last longer if you keep slow and steady feed rates and don't try to take on too many layers at a time if cutting flat stock. It's easy to chip a tooth on the edges of the steel both starting and finishing a cut. These chips mean that the next tooth in line will be forced to do more work and soon it will fail, and so on.

I had never cut aluminum. After some research I decided for safety reasons it was best to purchase a product designed for the job. Right tool for the job. I cut channelled aluminum 2" X 8" (Bleacher Seat or Plank). I saved the first cut so I could compare to my last cut. I made 90 cuts. The blade held up very well for my purpose. You have to cut slightly slower than you would cut wood, Although, as I neared the final cut, it seemed in my mind that the cutting ability of the blade was getting oh so slightly slower, but that is to be expected. There was no noticeable difference in quality of the 90th cut from the 1st cut. I think the blade will cut plenty more with no problem. There were no lost teeth or blade damage. Probable because aluminum is the product cut here, it leaves a large amount of debris. Probably no more than wood really, but because it is metal, it must seem like more because it won't lay flat on the ground after the cuts. You will want to wear eye, ear and leg protection. I am pleased with this product

I have found this dado set to be of very high quality and adaptable to many cutting widths. The cuts are smooth and the depths are even due to the relatively many carbide teeth. I was justified in the expense of the purchase compared with less expensive makes and models. I can sincerely recommend this dado set.

I love Festool, I buy their sanding pads for my rotex 150, I think you can't beat their quality products. I have to admit, forking out $125 for a replacement blade from Festool seemed steep. Went for this blade instead and let me tell you, this blade cuts just as good as the festool one, can't tell the difference, go for it. P.S: I cut wood only, not sure, if that's the case for other materials. Really glad I found this on Amazon.

The blades can cut either a 1/4" or a 3/8" dado slot depending on the saw blade orientation with each other. There is not indication on the cut where the blades come together, and the top of the cut is absolutely flat. They outperform by regular multi-blade dado set by far. However, they only cut the two sizes, so they are not going to be your go-to blades for all your dado needs. OUCH!! Hint: Wear gloves when handling these blades. They have SHARP edges just EVERYWHERE! I got the blood off of them before they started to rust and I WILL wear Kevlar shop gloves next time I install them on my saw!

This blade turned my vintage metal cutting saw a beast. Using this blade in the vintage Zip Cut metal cutting saw, I test cut some 1/8" x 3/4" aluminum flats and was thoroughly impressed. The flats were cut with perfect and clean cuts that do not require any follow-up deburring. I then test cut a brass bar - 1" x 1/2" and the results were simply perfect.

I only wish I'd bought this blade sooner.

This is a great blade. I’m using it on a radial arm saw. Cuts are clean and accurate. The negative hook gives me much greater control when cross cutting with the radial arm saw because the blade isn’t so aggressive while traveling through the wood. When ripping “one by” pieces of pine or plywood I don’t have to push so hard and it allows me to feed the wood through at the optimum rate. It’s much safer than using a blade that’s intended for a table saw.

I bought this blade for my Stihl TS 420 block saw. Although I'm sure the manufacturer would call it ill advised to say the least, I've shoved this blade into wood with embedded steel plates and bands, rocks, dirt, you name it. If your segmented concrete blade or disc shouldn't be used to cut it, then this is the answer. If you have a demo saw/block saw, this blade is the necessary third for a complete collection, for with all three there is virtually nothing you can not cut. Be forewarned, this blade is not for the meek. It is not like a chainsaw. It makes a chain and bar seem like kid stuff. Sawzall for pre-school girls. This will grab ahold of and rip apart virtually anything it comes in contact with, and isn't so forgiving like the discs and segmented concrete blades. With that said, it is way easier to use than you might expect. Look closely and you will see the carbide tips are set at a slightly negative angle, so it doesn't rip the saw out of your hands as easily as you might expect. DEFINITELY have the full blade guard properly installed and angled to protect from the shrapnel, and be wearing proper leg, hand and eye protection because this thing removes serious chunks of whatever is unfortunate enough to come in contact with it. I've put alot of miles on mine already, and it is fine. I can tell it isn't as fast as it was new, but for what i've done to it, it is impressive. I highly recommend this blade for commercial applications by qualified operators. You will not be disappointed. I would caution DIY folks to be sure you are competent to safely operate such an aggressive machine and blade combination, and that such an extreme setup is necessary. It is neat, and it is kinda fun, but definitely not a toy.

I've had a Festool track saw since around 2004. It's such a great tool that continues to work like new despite the fact that I don't baby it. Given the build quality of the saw, I have little doubt that the festool blades are premium quality and probably stay sharp longer than this cheaper blade. But so far the Oshlun is performing comparably, so no regrets or reservations about having it as a backup when I send the festool blades for sharpening.

As a complete novice woodworker, I watched YouTube videos of people doing amazing and easy finger joints with dado stacks. Most said for basic work you don't need to buy a really expensive set.

Well, maybe you don't, but do not go the cheapest set your local store has. Get these instead.

I bought a Skil brand dado stack for 40 bucks at a local store. I made about 5 attempts at notches. I adjusted them, I tried every blade they gave me. All the cuts were horribly uneven, had a lot of blowout in the back, and I was extremely disappointed with them. I uploaded pictures of the best ones.

I then decided to go with suggestions on these reviews and give these a shot, for not much more than my terrible Skil experience. I got them today, tossed them on, and made a cut (I'm just using a miter gauge and a clamp for the test cuts).

I was amazed. It was a lazy cut, I'm not using a sled like I normally would, I'm not even using a zero clearance throat plate. Just a miter gauge. And the cut was near perfect and uniform. I uploaded several pictures.

There is no blowout the back, and in fact I can't even tell which side I cut from just by looking at it.

While I'm sure these aren't as precision as a much much more expensive set, for the relatively cheap price these are very worth it. Get them and don't waste your time with skil.

I have a Skil table saw and not a newer model. I have a number of projects that I have wanted to do involving dado cuts. After reviewing many sites, I settled on the Oshlun stacked dado set. There were a number of reviews of Frued with trouble fitting to the arbor, I had no trouble at all with this set. Price line was another element. There are more expensive sets and lesser expensive sets. Not an Earth shattering discovery, but this one just fit my budget. I can't imagine those at twice the price being twice as good.
This set comes with 2 main 8 inch blades, 6 full body 6 tooth chipper blades (4 - 1/8, 1 - 1/16, 1 - 1/32), and an assortment of shims (8) wrapped up in a cardboard carrier. Not a fancy package, but I don't do this for a living so adequate enough for me.
I am a relative novice at this, but I was able to set up two different sized cuts in no time. Did a great job. Cuts were nice, no ridges, a really smooth bottom. A couple of practice cuts and your off and running.
For those who are just looking to get into this, you need a saw with at least 1.5 HP better with 2.0+ HP. You also need a dado inset for your saw. It took me a while to find one for my saw. And it really wasn't advertised for this blade size, but it worked. You can attempt to make your own, but I just wanted to plug and play as soon as possible. Amazon, as always, did a nice job in delivery. A nice set. Can't say much about durability as yet. Time will tell.
