Core Bits

Gryphon Diamond Core Drill Bits

Core drill bits have a hollow center and cut a circle in the material to create a hole. This results in a hole the size of the drill and a smaller "plug" or "core" which comes from the center.  Just add water for lubrication.  All diamond core drills have shaft sizes of 3/8" (10 mm) or less, for use in most standard drills and drill presses.

IMPORTANT:
Diamond drill bits require the use of proper lubrication, correct drill speed and proper pressure.
