Review: Impressive metal cutting at a good price - 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.
Review: Way better than expected - These things are great. They last much longer and cut better than most throw away discs. I've bought several other kind including the "diamond blades" that are supposed to last a long time but don't. These are the best I've ever used for the money. I've seen a few reviews about the centers coming loose or they are too thin but that seems ridiculous. I haven't had one center break loose but I imagine if you beat on one while it's spinning that could happen. And as far as too thin, learn how to use it. You cut straight, you don't turn, you don't sit your grinder down on the blade, and don't try to crank them on by turning the blade with your hand. Them being thin is how they can cut so quickly. These are all I'm buying from now on.
