Questions & Answers
These wheels cut through 1/4" steel faster than any other cutoff wheels I've tried, and because aluminum is much softer than steel, cutting 1/4" aluminum should be as easy as slicing butter.
It was 7/64 in my experience, which is 1/8 of a difference from 7/64, so it wasn't what I wanted; hopefully this helps.
The RPM rating appears to be different in Amazon's image. The A stands for 3900 and the B stands for 4400.
Yes, but it is primarily used to burn through wood. In a pinch, I've done it, but it's not something I'd recommend.

For things like rebar, powered saws are required, but this is not the case! This blade is only for cutting metal on a bench. off saws with lower horsepower and RPM than gas-powered quickie saws designed for concrete cutting After one blade became severely warped and you could tell there was a problem, you can read the details about the blade and see the pictures explaining what the blade is for. I spoke with the local rental store, and they explained that only certain blades are meant for the quickie saw, and I included a picture that explains DeWalt makes one with higher RPM and even shows a picture of a quickie saw, which is a little thicker but does not warp and works perfectly. I'm dissatisfied with the misleading description on this page. So only use this sawblade on a bench type machine; it will not work on a gas machine!.
year- The wheel I had on my old Makita abrasive cutoff saw simply slowed down the motor without cutting anything. I was fortunate in that I had ordered a package of five wheels, and I was able to switch wheels right away. On the second try, it took 45 seconds to cut through 1/4x3x3" angle iron. I'm working on a project that requires a lot of steel, and I've already cut at least fifty times, and the first of the five wheels still has plenty of life in it. I've always admired Makita products, but this set of wheels not only lives up to Makita's high quality standards, but it's also a fantastic value.
I purchased a Dewalt chop saw, but the blade that came with it was nearly useless and could not cut well. br>I expected this to happen, so I bought extra blades in case the composite one broke or chipped, much like angle grinder blades do. br>These are reasonably priced and have a reasonable life span when compared to the stock blade; there are diamond-costed blades that could last much longer without losing their size, but they're $100. br>These are also quite thin; I've made about 30 cuts on 1" square tubing with a 1/4" wall, and the blade is still only about 1/2" worn out. br>It comes highly recommended.
For the past two decades, I've been using Makita chop saw discs. I used to go out and buy whatever was the cheapest. They also didn't last as long and would usually deflect if you yanked them down too hard. The Makita disc is more rigid and harder than the others. I cut oilfield tubing that is close to schedule 80, and I wouldn't cut it without a bandsaw. When you cut angles, you can tell the difference. They're also at a great price!.
I ended up making five cuts and went through a little more than half of one blade with no problems; it cut perfectly. It's not a race, so take it slow and steady. Yes, it's a bit of a pain in the neck. Then why? Because I'm cheap, and if you order a beam that's less than twenty feet long, they 1) charge you to cut it, and 2) charge you for twenty feet anyway, because the remainder is scrap. So I saved about $150 by spending the $20, and I still have four blades left over for future use. Plus, while I don't have a torch, I do have a cut-off saw.
Even thin mild steel isn't a good choice. I have a great Milwaukee chop saw that I've only used once or twice. This was a breeze to install. It, on the other hand, isn't very effective. I was cutting thinner angle steel (not hard steel) and it took a lot longer and required a lot of force to cut. It would just spin against it if it wasn't for the fact that it was spinning. IDK. Nothing compares to the sensation of a hot knife cutting through butter that I had with the original Milwaukee wheel. I'm dissatisfied, and I'm concerned that it will damage my chop saw. I came to a halt and double-checked that this blade was for steel and that I hadn't accidentally picked up a masonry wheel or something. It's adorned with a steel symbol. I believe I will attempt to complete my current project before discarding all five of these. Keep one in case something goes wrong. I'm not willing to risk my saw. I'm a little disappointed.
It was a good match for our cut-off chop saw, which I liked. It appeared to be a fraction of an inch thinner than the original blade. The multipack, on the other hand, will make up for it; I used it to cut metal and it worked perfectly. This product meets my expectations, based on my previous experiences with Makita products. Would suggest If necessary, repurchase.
I've gone through a lot of cutting discs while building a fence out of drill pipe. Because I had given up on Diablo brand discs and returned them to the big box depot, I ordered these. They didn't do anything but generate heat. br>br>Today, I used one of these Makitas and it did a much better job cutting through that 2 3/8" steel pipe; I'm glad I bought these.
