Mini Diamond Drill Bits/Cores
These popular inexpensive mini diamond cores are intended for low usage drilling through most types
of tiles. They do not have the wear life of the Porcelain / Granite Hole Saw range or
Diamond Drill Bits shown below, but can be used
where only a few holes are required. A normal high speed rotary power drill should be used.
Solid Segment Diamond Drill Bits
These solid segment diamond drill bits drill up to 100 holes in hard Villeroy and Boch tiles, and are the only drill bit specifically endorsed by Villeroy and Boch.
Porcelain/Granite Hole Saws
Compared with the mini diamond cores these have a life approximately thirty times as great.
