What is the difference between your diamond resin wheels and diamond rez wheels?

Both of these wheels are diamond resin wheels however, the resin bond formula is slightly different between the two wheels. Our diamond Resin REZ Grinding wheels are manufactured with an aggressive resin bond, re

sulting in a rough texture with sharp points and are more durable than our standard Diamond Resin Sfot Wheels (see image above for close-up of rez and resin wheel texture). Since the rez wheels have a rough texture with sharp points, they require a break-in period while our diamond resin wheels do not. All rez wheels come with instructions for proper use and care.
