Eagle Cutting Tool 1090-126-I Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-126-I is a high-speed steel (HSS) Silver Deming drill bit with a 1-13/32 inch cutting diameter and a reduced 1/2 inch straight shank. Silver Deming bits are designed to bore large-diameter holes in metal, wood, and plastic where standard jobber-length bits cannot reach the required diameter. The reduced shank allows this oversized bit to fit in standard 1/2 inch drill chucks, making it a practical choice for machinists, millwrights, and maintenance technicians working with common drill press or hand-drill setups. The HSS construction holds a cutting edge under moderate heat and is suitable for general-purpose production and repair work.

This drill bit is used in metal fabrication shops, maintenance and repair operations, and light manufacturing environments. Typical applications include drilling pilot holes and clearance holes for large fasteners, conduit knockouts, and bearing bores in mild steel, aluminum, cast iron, and similar materials. The import designation indicates this is a cost-effective option suited for lower-volume or intermittent use rather than high-cycle production runs.

Key Features

• 1-13/32 inch cutting diameter for large-bore applications
• Reduced 1/2 inch shank fits standard drill press and hand-drill chucks
• High-speed steel construction resists heat buildup during drilling
• Silver Deming style provides rigidity and stability in oversized diameter drilling
• General-purpose design suitable for metal, wood, and plastic substrates

Compatibility

Designed as a general-purpose Silver Deming drill bit compatible with any drill press or power drill equipped with a 1/2 inch or larger chuck capacity.

Installation Notes

This bit should be installed and operated by a qualified machinist or experienced tradesperson. Secure the workpiece firmly before drilling and use cutting fluid on metal substrates to extend bit life and reduce heat. Start at a lower RPM appropriate for the large diameter and material being drilled. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
