61/64" Silver and Deming Drill Bit

The Drill America 61/64" HSS Silver and Deming drill bit is built for heavy-duty metal drilling in maintenance and fabrication shops. Its reduced 1/2" shank allows use in standard drill chucks while the 3-flatted design prevents slippage under high torque. This tool targets professionals who need a large-diameter hole without a specialised machine taper.

Straightforward Chucking and Chip Control

The three flats on the shank make installation quick and secure in any 1/2" capacity chuck, requiring no additional sleeves or adapters. Surface-treated flutes help evacuate chips during deep cuts, reducing the chance of binding. Users should ensure their drill press or hand drill delivers enough torque at low speed, as insufficient power is the common cause of premature wear or breakage.
