Hole Shot Dry Bits

For use with 5/8"–11 thread grinders.

The RTC Hole Shot is a porcelain core bit engineered for minimal to no water use on grinders with a 5/8"–11 threaded spindle. Each bit is designed to drill clean, accurate holes in hard materials while running dry, making it ideal for on-site work where water control is difficult.

Vacuum-brazed diamond segments provide fast cutting and long life, delivering up to 40 holes per bit in typical porcelain applications while still performing on granite, marble, and other dense surfaces.
