Eagle Cutting Tool 1080-128-D Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1080-128-D is a high speed steel (HSS) Silver Deming drill bit with a 1-7/16 inch cutting diameter and a reduced 1/2 inch straight shank. Silver Deming bits are designed for drilling oversized holes in metal, wood, and other materials where a standard jobber-length bit would not fit a conventional chuck. The reduced shank allows the bit to seat in a standard 1/2 inch drill chuck despite the larger cutting diameter. This is a USA-manufactured tool commonly used by machinists, pipefitters, plumbers, and HVAC technicians for field and shop drilling applications.

This drill bit is suited for drilling through ferrous and non-ferrous metals, plastics, and wood in both residential and commercial trade applications. Typical use cases include enlarging existing holes, drilling conduit knockouts, pipe penetrations, and equipment mounting holes. The 1/2 inch reduced shank makes it compatible with standard corded drill presses and heavy-duty hand drills commonly used in the field.

Key Features

• 1-7/16 inch cutting diameter for oversized hole applications

Compatibility

Installation Notes

This bit is intended for use by machinists, pipefitters, plumbers, and HVAC technicians using a drill press or heavy-duty corded drill. Secure the workpiece firmly before drilling and use cutting fluid when drilling ferrous metals to extend tool life and improve hole quality. Inspect the cutting edges before use and replace the bit if chipping or excessive wear is present.
