Great bit

by - verified purchaser
The only bit that worked for us drilling hard porcelain tile.Up to 24 holes and the bit is still going strong(1/4 inch). Just follow the directions as described. We tried many others and got nowhere.

Cut through glass subway tile with ease

by - verified purchaser
Using the spear shaped bits available at the big box stores are a waste of time and money. Unfortunately I wasted many hours, numerous pieces of tile, and bought several useless bits before I learned that lesson. I'll never attempt glass drilling again without these diamond bits.

First time

by - verified purchaser
I just had two bathrooms professionally completed and decided to install a grab bar in the shower after they had left. The contractors had remarked about their difficulty in securing cabinets to the walls since the tile was unbeliveably hard so I was apprehensive about cutting 1 1'/4" holes into it. As a first time use of any bits for tile, this one was a breeze to use and not one chip on the finished holes!
