How Do You Use A Diamond Core Drill Bit For Porcelain Tiles?
Porcelain tile has a very hard finish. Drilling holes in porcelain is often necessary for the installation of plumbing, fixtures and sinks or assistance grab bars in shower areas and adjacent to commodes. The best way to drill larger holes in existing porcelain tile is with diamond-tipped hole or core bits and a variable speed heavy-duty drill. Tape the porcelain tile with painter’s tape at the location where you want to drill the hole. Draw a circle on the tape of the exact size you want to drill. Roll putty into a rope long enough to comfortably surround the hole you want to drill. Press the putty tight to the tape and tile. The putty should be about 1/2 inch from the hole on all sides. You are creating a water dam that will be used to hold water to lubricate and cool the bit while you are using it. Fill the putty ring with water as high as possible. There are lubrication holes on the bit to help water flow around the bit. Ring the putty tall enough for the water to cover these holes
