After reading the great reviews, I had to get it when I saw it on sale. This is a steal at the sale price and worth every penny at the regular price. It cuts perfect joints with flat bottoms. I should have bought them sooner.

Bought this blade to cut 1/8" thick rectangular tubing for a project I'm making. I got about 50+ cuts on it now and seems to wearing out just a tad now. I could not tell the difference between this blade and the Milwaukee metal blade and this blade is a lot cheaper.

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.

Good fit. Initial cuts worked well. I made 80+ cuts through that were 1-7/8" deep in 1" thick alum flatbar.
About 2/3s of the way through the blade started to struggle, but we were able to complete the project. Would probably recommend a cutting lubricant next time.

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.

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.

This is an interesting story. I had an aluminum decorative fence to install in my backyard and went to Lowe's and Home Depot to find a non-ferrous blade. Neither had one in stock, so I turned to their web pages. In both cases, navigating their web pages was so laborious, I gave up. I figured there was no way that Amazon would have the blade, but I gave them a shot anyway. To my surprise, they had it! If I were Lowe's and Home Depot, I'd be very embarrassed.

Anyway, the blade has worked great. I have made over 100 cuts with it so far and it doesn't seem to be getting dull. Not only that, the blade cuts through aluminum cleanly and smoothly like a hot knife through butter. I really couldn't be more satisfied with my purchase.

Have done a lot of wood working projects over the years. Have done carpentry on houses. Have done fiberglass work for boats. This was my first foray into Aluminum/Metal cutting. Purchased a 16' X 16' Mechanical Pergola kit for my home and needed to trim the beams, louvers, posts for the install. Purchased a 12" Compound Miter saw from Northern tool and upgraded the blade to this 120tooth metal cutting blade and OMG it was good! Cut 1000lbs of aluminum and it was cutting just as good on the last cut as the first cut. Well worth the money for the quality of the cutting. Beware though cutting metal is nothing like cutting wood! Clamp everything and be sure to keep the items you R cutting firm otherwise you'll get into trouble. I quickly learned as several items kicked and I broke a 2 teeth from this blade but for the rest of the project it kept cutting like they were not even missing.

Very nicely machined. It moves and holds its position very nicely. Easy to read dial; easy to read numbers. The fractional numbering on the outside of the dial, which makes the fractions easier to see. The decimal scale on the inside of dial is more natural to look at and the smaller size is not a problem to read. Other more expensive fractional calipers I have seen are much harder to read. Very nice for the price.

I've been using it for a while on my old radial saw. I cannot imagine not having it. It is so dead-on accurate I can cut a piece of MDF that is wider than my blade travel by simply making one cut and then flipping the piece over and lining up the edge for a second cut in the opposite direction of travel. It is bright enough for the majoritiy of my cuts - but if it were a bit brighter I'd give it six stars!
NOTES:
Based on the one I'm using, reviews describing it as "out of balance" seem nonsensical.
It's ready to go out of the package. The included batteries are spares.
I used a short piece of stiff wire (brazing rod) to line up the laser hole between two teeth on my blade and it worked perfectly on the first try.

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 had been delaying this purchase and finally ordered it. There were several chipped teeth on the first set. Absolutely no problems with return and replacement. Customer service the way it should be. Now, the dado set - A lot of teeth and real blades, not lightweight wings and they cut a FLAT dado with no tear out on the bottom or on the sides of the cut. The dado almost looks like it had been polished. Kinda makes me a little mad that I waited so long to make the purchase. I honestly cannot see how any other brand could make a better cut, regardless of the cost. Buy this one. You will not be sorry. For those that are concerned about the box - Exactly how much wood does a box cut? Besides, it gave me a new project.

Works great so far. Who needs a $300 Milwaukee metal cutting saw when I can just put a $30 blade on a ghetto saw? I should take this to work just for the lolz.

I just received this today and I put it on my 12" miter saw to use the saw as a chop saw. I cut a piece of 1-1/2" x 1-1/2" 6061 aluminum. It cut that piece like it was hot butter. I used the Olsun blade lubricant before I did the cutting. No effort at all.
My next cut will be on a 2 1/2" x 2 1/2" of the same metal. If it cuts the same way, this blade is worth twice the price.

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.

It's a good value. Of course it's made in China. Be sure to order a lube stick to use with it. If you are cutting thinner material like angle or box tubing, get the 120 Tooth. If you are cutting heavier bar stock, large rounds, get the 80 tooth. I ran the 120 tooth on some 3"x4" 7075 bar stock and it wanted to plug up even with plenty of lube.

This is an amazing saw blade for the price! I would suggest this blade to anyone with a cold cut saw. I bought one of these for a project to see how it would do on my Milwaukee Metal Cutting Circular Saw and it did better than the blade that came with the saw. I cut through 60ft. of 1/4 inch thick steel with no problem and the blade still had plenty of life in it. I only had to slow down because the saw itself got to hot to hold.
I bought 3 more of these blades after the first one, if you have a cold cut saw that uses an 8inch blade this is the blade to get. The price is great and the quality is fantastic.
This is defiantly a great buy not just for the money but for the quality.

I love this blade. I installed it in my cabinet saw and so far I've cut hardwood, plywood, and plexiglass without any issues. The surface that is left is super smooth - feels as if it were sanded by a 300+ grit sandpaper!
I can't comment on the longevity of the blade sharpness but after owning it for couple of months it's held up very well.

This blade is a great bang for the buck. It’s well made, has thick C-4 micrograin carbide, expansion slots with copper silencer plugs, and a stiff precision steel body. It’s very capable of glue ready edges right off the saw, and does a good job in many materials…it does everything a dependable general purpose blade should do. […] It clearly outperformed my $60 40T CMT 213.040.10. Hard to go wrong at the price.

Purchased this blade to cut some aluminum deck railing. Was afraid that I was going to have to cut with a hacksaw. My buddy recommended an aluminum cutting blade (which I had never heard of) for my compound miter saw. I also bought blade lube/wax as recommended. I was leary about cutting expensive railing this way. This blade cut like butter with smooth, precise cuts. It made the job easy, almost pleasurable. Glad that I used it.

We bought this for removing a breezeway between two buildings. We had to cut walls and the shingled roof, and then removed pieces with an excavator. This made the job pretty easy.
This blade is really heavy, and takes a bit ti spin it in the saw, but once it gets going, will cut through anything without issue. Cutting with it is pretty easy, if you can handle the hefty weight, otherwise it's easy to control.
Only downside was that it was definitely getting dull towards the end of the job. We had it sharpened, but haven't used it since, so we'll see if it's still usable or not.
