Eagle Cutting Tool 1080-109-D Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1080-109-D is a High Speed Steel (HSS) Silver Deming drill bit designed for heavy-duty drilling in metal, wood, and hard plastics. With a full 1-9/64 inch cutting diameter and a reduced 1/2 inch straight shank, it fits standard 1/2 inch drill chucks without requiring an oversized chuck. Manufactured in the USA, this bit is suited for machinists, maintenance technicians, pipefitters, and fabricators who need reliable performance on oversized hole applications where standard jobber bits fall short.

Silver Deming bits are the standard choice when drilling holes larger than 1/2 inch in steel plate, structural members, pipe flanges, and mechanical components. The 1/2 inch reduced shank allows the bit to seat in common portable and benchtop drills, making it practical for both shop and field use. This bit is appropriate for light manufacturing, mechanical contracting, HVAC rough-in, and general fabrication work where clean, accurately sized holes are required through ferrous and non-ferrous materials.

Key Features

• HSS construction provides hardness and heat resistance for drilling steel and hard materials
• 1-9/64 inch cutting diameter for oversized hole applications
• Reduced 1/2 inch straight shank fits standard 1/2 inch drill chucks
• Made in the USA
• Silver Deming style for compatibility with common portable and drill press setups

Compatibility

Designed as an OEM-style Silver Deming drill bit compatible with any 1/2 inch keyed or keyless chuck on portable drills and drill presses requiring a 1-9/64 inch bore diameter.

Installation Notes

Silver Deming bits should be installed in a drill press or heavy-duty corded drill with a securely tightened 1/2 inch chuck. Use appropriate cutting fluid when drilling ferrous metals to reduce heat buildup and extend bit life. Always secure the workpiece with clamps or a vise before drilling to prevent rotation. Wear appropriate eye and hand protection per applicable shop safety standards.
