Review on X 040 Depressed Center CutOff Wheel by Jack Enhanced

Of the three or four I've used to date, all began to fail or fail during use. The center seems weak and after some use (once wear reaches 50%) they start to break where it pinches. The first one I used was throwing pieces everywhere. After that, I watch it and see where the center started to crumble. I can attest that I don't use the center of the blade as a grinder or anything like that and have never had this problem with Diablo blades I've bought from Home Depot in the past. Make sure you wear a protective mask. I'll probably buy Diablo Blades again once I've finished them, but maybe I'll just throw them away when they're 50% worn.
