I've been through a whole pack of these on my angle grinder and they hold up way better than the cheap cloth ones I used to get. The hook-and-loop backing stays firm even after switching discs a dozen times, and the 4 1/2" size fits my backing pad perfectly.

The 8 holes really do their job keeping dust from clogging the disc mid-sand. I've been through a whole pack on my angle grinder and the hook-and-loop backing still grabs tight with no slipping, even after heavy use on rough metal.

Cut through stainless like butter with these 4 1/2" zirconia discs—the 8-hole dust extraction really keeps my work area clear. A solid step up from my old aluminum oxide ones.
