Benchmark Abrasives Grinder Cut Off Wheels 4 1/2 Inch Aluminum Oxide Thin Type 1 Angle Grinder Cutting Disc for Metal, Stainless Steel - with 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.

I like them work good and good price

I bought 25 to try them out, and I was very impressed. I cut all kinds of steel from thin to thick. I used a lot of them on drill stim pipe 2 3/8 and 2 7/8. They even seem to last longer. Just ordered another 50.

Good quality product at a good price!

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

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!!!

I’ve used this brand for years. Haven’t found a better quality cut wheel or flap wheel. Theses stay consistent, don’t blow up, cut clean thin lines. Awesome brand!

SO far these are the best wheels I've used to date. I've been working with metal my entire life and these last a long time and are priced right!
