1-15/64" HSS Silver & Deming Drill Bit

This Drill America bit is a high-speed steel Silver and Deming drill designed for enlarged hole cutting in metal and other materials. It features a 1/2" reduced shank to fit standard drill chucks, making it suitable for maintenance, fabrication, and general workshop tasks. The surface-treated flutes enhance chip evacuation and wear resistance during operation.

Easy installation with reduced shank

The 1/2" reduced shank allows direct insertion into most standard drill chucks without requiring a larger capacity chuck or special adapters. Users must ensure the chuck is tightened securely to prevent the bit from slipping under high torque loads. A common issue occurs when the workpiece is not clamped firmly, causing the bit to grab or chatter during the cut. Proper cutting lubrication is essential to prevent premature wear and overheating of the high-speed steel flutes.
