Eagle Cutting Tool 1090-107-I Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-107-I is a High Speed Steel (HSS) Silver and Deming drill bit designed for boring large-diameter holes in metal, wood, and similar materials. The reduced 1/2-inch shank allows this oversized bit to fit standard 1/2-inch capacity drill chucks, making it practical for use with common portable drills and drill presses. At a cutting diameter of 1-7/64 inches, this bit handles hole sizes that fall beyond the range of standard jobber-length sets. HSS construction provides solid heat and wear resistance for general-purpose industrial and trade applications.

This drill bit is suited for machinists, maintenance technicians, HVAC installers, plumbers, and electricians who need to bore large clearance or rough holes through metal plate, structural steel, wood framing, or similar substrates. It is commonly used in light manufacturing, field service, and mechanical rooms where large-diameter holes are needed without access to a full set of Silver and Deming bits. The 1/2-inch reduced shank makes it compatible with widely available drill equipment on job sites and in shops.

Key Features

• 1-7/64 inch cutting diameter for large-bore applications beyond standard jobber bit range
• Reduced 1/2-inch shank fits standard 1/2-inch drill chucks on portable drills and drill presses
• High Speed Steel (HSS) construction resists heat buildup during metal drilling
• Silver and Deming style design for controlled, stable cutting at larger diameters

Compatibility

Designed as a general-purpose Silver and Deming style drill bit compatible with any 1/2-inch chuck drill press or handheld drill. Suitable for use in metal, wood, and similar materials where a 1-7/64-inch bore diameter is required.

Installation Notes

This bit is installed and operated by machinists, tradespeople, and maintenance technicians using standard drill presses or 1/2-inch chuck portable drills. Secure the reduced shank firmly in the chuck before operation and confirm the workpiece is clamped or secured to prevent movement. Use appropriate cutting fluid when drilling metal to extend bit life and reduce heat. Follow applicable shop safety standards and wear eye protection during use.
