Benchmark Abrasives Grinder Cut Off Wheels 4 1/2 Inch Aluminum Oxide Thin Type 1 Angle Grinder Cutting Disc for Metal, Stainless Steel, 7/8" Arbor Hole, Fast Grinder Cutting Wheel - 50 Count

Not sure what these negative reviewers are talking about. I used some of these cut off disks today. They tore through mild steel like it was butter and didn't even lose much of their size while doing it. They did, however, lose some of their overall size when I cut some stainless steel sheet metal and then cut through some 1/4 inch AR650 ballistic plate (I expected that to happen with both steels). I also noticed a negative reviewer stated that the center metal disk became unattached, and then someone else said that the disk shattered. I can only assume that in either case, the users were inexperienced with metal cutting with these kinds of disks, regardless of their described experience (unless they got a bad batch, which is highly unlikely, but never impossible). The flaws that the previously mentioned negative reviewers described can be generally attributed to applying too much pressure when cutting. With cutting disks like these, you use almost no pressure and let the disk to all of the work. It should also be mentioned that, if the outer edge of the disk has a crack or chip in it, it should be discarded as there is a pretty good chance that it will shatter. I've used just about every brand of metal cutting disk at different points in my career (and for personal use), and can comfortably recommend these metal cutting disks if used properly. Summary : A capable, cost effective choice for angle grinder metal cutting. PS: Generally speaking, I am normally disgusted with most of the things I buy due to poor quality nowadays (I'm a curmudgeon like that) so when I take time to recommend an item, there must be something good about it, otherwise I would have broken out the verbal fail hammer review.

Have only used one so far. I was pleased when I made the first cut. Every other cuttoff wheel I've used "jumps" when you first start cutting with a brand new wheel. This one didn't at all. I'm hoping the whole pack will be that good. Makes nice clean cuts and seems like it will last a good while. This pack of 50 should last me for a long time. Also, I'm using a Makita grinder. I've had problems with other wheels fitting way too tight on the arbor. As in, I couldn't even push it all the way on with my hands. I had to tighten down the nut on it to get it to seat. These slipped right on with no problem at all. The other brands I've used, they sell on Amazon too. Brand DeW and brand W. I pretty much despise brand DeW cuttoff and grinding wheels.

I like them work good and good price

Why did you pick this product vs others?: best for the money I've found. Cut well, last.

They cut fast, straight and don't kick back. Really good product for the price. I'm a sheet metal worker in Chicago, downtown everyday doing big stuff and I go through wheels like crazy. I know what is good and what isn't these r good. The only bad thing is not really for homeowners. Too many come with it it comes with a cardboard box but if u use these sporadically in sure u will only get about half use from wear and tear of moving the, storage, etc .

Best cutting wheel by far. Unfortunately I have been using a cheaper version for years until now. These last 3x as long, less pressure to get the job done and again lasts longer. Defiantly buy again!!!

Works very well. Good price.

I am glad I learned about these cut-off wheels before I go too old to use them. Cut-off blades mounted on the right tool replaces a hacksaw and makes metal cutting easy.
