1in HSS Reduced Shank Drill Bit
The Drill America Silver and Deming bit is a high-speed steel cutting tool with a 1/2in reduced shank designed for use in drill presses and heavy-duty portable drills. Its 1.0000in cutting diameter and 6in overall length suit metalworking shops and maintenance departments that need to enlarge existing holes in steel or cast iron. The surface-treated flutes improve chip evacuation during deep drilling operations. This bit is not for buyers who need a full 1in shank for direct collet clamping or who require carbide tips for abrasive alloys.
Installation and common issues
The reduced shank fits standard 1/2in drill chucks without adapters, so setup is a simple chuck-and-tighten procedure. Because the shank is smaller than the cutting diameter, the bit can slip under heavy feed pressure; apply steady, moderate force and use cutting fluid to prevent grabbing. Over-speeding the drill causes premature flute wear, while insufficient lubrication leads to work hardening and bit breakage. Ensure the workpiece is rigidly clamped to avoid vibration that damages the cutting edges.

Questions about this item
How can I confirm the 1.0000 inch Silver and Deming drill bit is cutting correctly after I install it in my drill press?
The bit should produce clean, consistent chips and a round hole at the 1.0000 inch diameter without excessive vibration or burning when run at the proper speed for the material.
What comes with the 1.0000 inch Silver and Deming drill bit and what must I supply separately?
The package contains the single 1.0000 inch HSS drill bit with a 1/2 inch reduced shank; you must provide the drill press or power drill, cutting fluid, and any required work-holding fixtures.
