Eagle Cutting Tool 1080-116-D Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1080-116-D is a high speed steel (HSS) Silver Deming drill bit designed for heavy-duty drilling applications in metal, wood, and composite materials. Built with a reduced 1/2 inch shank, this bit fits standard 1/2 inch drill chucks while delivering a full 1-1/4 inch cutting diameter. The Silver Deming design allows trades professionals to bore large-diameter holes that exceed the capacity of standard jobber bits. Manufactured in the USA, this bit is a go-to choice for electricians, plumbers, pipefitters, and HVAC technicians who need reliable, oversized hole-making in the field or shop.

This drill bit is suited for use in ferrous and non-ferrous metals, wood, plastics, and similar materials where a large-diameter hole is required. Typical applications include conduit knockouts, pipe penetrations, panel work, and structural drilling in both residential and commercial settings. The reduced shank design makes it compatible with common 1/2 inch capacity corded and cordless drill drivers and drill presses.

Installation Notes

This bit is typically installed and used by electricians, plumbers, HVAC technicians, and pipefitters. Secure the reduced shank firmly in a 1/2 inch drill chuck before operation and verify the chuck key is removed prior to starting. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and reduce heat buildup. Always wear eye protection and secure the workpiece before drilling.
