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

Knock on wood I’ve used over a hundred of these cut off wheels and haven’t had one come apart on me like other brands. They cut really well and last a decent amount of time. I love the price and will continue to buy Benchmark Abrasives

Shipping was fast , Great product and cuts sheet metal fantastic, I will be buying from this seller again and this cutting wheels all that I'm buying from now on.

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.

Seem to last longer than alot of other equally priced discs.

Hello , I am a scrapper and have been buying these cutting disk for 7 years. They are a great value for the price. These last 2x longer cutting stainless steel than any brand I have bought. I can process 100 lbs of Aluminum with 1 disk. This year I have used over 100 & only 2 broke while cutting.

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 .

It’s a really good product. I’m amazed at how much cutting I have been able to do with one blade.Holds up better than DeWalt and other Big Box brands, and only about $.60 per cutoff wheel.

Better than some I have had, last longer.

Very good stuff, bought last year, almost spent all of them. Think it is time to buy again.

As good as popular name brand at less than half the price. Will be buying again.
