Diamond Drill Bit integrated with high-quality cooling wax, dry drilling without water,Vacuum Brazed technology and high quality diamond grains provide high efficient working and long time performance.

In remodeling two bathrooms with porcelain tile I had to drill a number of holes in the tile for the glass panel supports/clamps. I went through four or five bits and a lot of time drilling for the first three panels. I bought these for the last panel and the drilling was much, much faster and easier. I drilled 10 holes with one bit and it was still in relatively good shape when I finished.
