Review on 🔹 Raizi Precision Porcelain Diamond Milling and Enlarging Cutting Tools by Andy Baker

I bought this because I needed to enlarge some holes in a tile vanity to replace a bathroom faucet. Neither the contractor nor the plumber wanted to do this for fear that they could break the tiles and be held responsible. So I ordered these and rented a small coffee grinder and it worked great. Just a few minutes of work and he made very clean, smooth holes with no risk to the tiles.
