Diamond Drill Bits & Core Drills

Crinkled Core Drills

Crinkled core drills are used on stones and glass. They are used frequently for making holes in clock faces and wine bottles for lamps. The crinkled edge design quickly removes debris for more diamond cutting surface contact. They are coated with 120 grit industrial diamond. Use these crinkled core drills on a drill press ideally with a water swivel adapter.
