Review on 💎 Z LION Diamond Granite Grinding and Sanding Tools by Bryan Fisher

This is a serious tool or bit to have in your arsenal. I needed this to open a sink faucet hole through granite. The new crane was a little bigger and was afraid to jump with a different style. It plugged directly into my Porter Cable angle grinder and in less than 2 minutes I was done. Smooth clean hole. And yes, use a shop vacuum.
