Wow, I"m impressed!I was happily slicing up a cylinder head with my 4.5" grinder, going through the wheels at the rather typical rate. Ran out, so I needed some more. Went out and bought some DeWalt wheels, since that"s what the store had. I immediately bound the wheel when I re-started the cutting, twisting the grinder out of my hand. Figured I"d just broken a brand new wheel with less than a second of use on it. Nope! The wheel didn"t break! Pull it all out of the engine and examine it closely for fractures. I"ve blown up wheels before, and don"t like it. Nope, no cracks. Fire it up, and it goes just fine. The wear rate of the wheel is roughly half that of any other wheels I"ve used. Dang, this thing just isn"t wearing down! Not even when I get the wheel jumping a bit, which usually eats the wheel down in nothing flat. No chunking either. In summary, I"m really impressed by how well the wheels cut, how slowly they wore down, how well they stood up to abuse like flexing and jamming. This is a wheel well work looking for in my opinion.
