Customer Reviews

1 in. Diamond Drill Bit is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Very quick tile cutting, but best if used in a drill press. After going though several carbide hole saws and not getting anywhere on porcelain tile, I tried this diamond bit. Huge improvement! Keep the bit wet and it glides through. I did find the sidewalls a bit weak when using in a handheld drill. If you get off center and try to correct, it can easily bind and completely bend the sidewalls ruining the bit. If at all possible use a drill press.
