Drill bit for 53/64 inch holes

This Drill America D/A3F53/64 accessory is a high-speed steel Silver and Deming drill bit built for creating 53/64 inch diameter holes. It features a 1/2 inch reduced shank with three flatted surfaces for secure chuck grip and surface-treated flutes for chip evacuation.

Fits 1/2 inch chucks with three-flat grip

The reduced shank allows the bit to be held by standard 1/2 inch drill chucks while cutting a much larger 53/64 inch hole. The three-flatted shank prevents slippage under high torque, freeing the user from needing a larger-capacity chuck or specialised tool holder.
