Must Have for Porcelain Tile Work

by Retired in Larue -

I had to install a towel rack in a porcelain tile shower. I tried three other drill bits that claimed to be for porcelain. I spent over two hours and had not drilled one hole. It took me about 10 minutes to complete all four holes with this bit. It is a must have if you are trying to drill through porcelain tile.

After about the fourth hole, I needed to apply more presure.

I installed a shower door on grade 5 porcelain. Drilled each hole in less than 2 minutes, compared to 10-15 minutes per hole with diamond core drill bits. Excellent product. Great quality. I will recommend it to everyone.

Great Drill Bit

by Roger -

I Bought a 1/4" PTC drill bit to drill holes in my porcelain tile shower installation. It works great. I was drilling grade 5 porcelain tile. I placed the tile in a shallow pan, poured water in so that the tile was about 1/2" underwater. Then placed the drillbit underwater against the tile and drilled ! I have drilled 8 holes and it is still working great.

Had expected to last longer

by tgbrendoni -

This is a impressive drill bit which does not use percussion and it worked for the first three holes and keeping it on the mark. After that, more force was required to bore through the porcelain to the point where it cracked the tile. I had expected them to last a bit longer than that.
