Drill Bits for Glass and Ceramic
 |
Core Bit |
Quickly create large holes in sheets of glass and ceramic using a drill press. These bits drill smoothly through fragile materials, reducing the chance of chipping and cracking. They have a diamond coating, the hardest finish for the longest life. Bits require an adapter (sold separately) to supply coolant during drilling.
