Review on PorcelainPlus Speedbit Tile Glass Bit by David Everett

Creating a clean hole in a thick piece of porcelain shouldn't be an easy task. With that attitude and after reading user reviews, I decided to give it a try and ordered it. I followed the instructions and using a battery powered drill, started the slow drilling process for 8-10 seconds at a time, inserting the drill into the water each time. Patience is key, and this includes using only light or moderate pressure.
