Eagle Cutting Tool 1090-125-I Hss Drill Bit 1-25/64 in

Product Description

The EAGLE CUTTING TOOL 1090-125-I is a high-speed steel (HSS) slow-spiral (SD) drill bit sized at 1-25/64 inches with a 1/2-inch reduced shank. Slow-spiral geometry reduces chip packing and heat buildup when drilling through softer metals, plastics, and wood composites at larger diameters. The 1/2-inch shank allows the bit to seat in standard 1/2-inch keyed or keyless drill chucks without requiring a large-capacity chuck. This bit is suited for machinists, fabricators, maintenance technicians, and trade professionals who need accurate large-diameter holes in production or field settings.

This drill bit is appropriate for use in drill presses, magnetic base drills, and hand-held power drills equipped with a 1/2-inch chuck. Typical applications include drilling clearance holes, access holes, and rough-bore openings in metal plate, structural steel, aluminum, plastics, and similar materials. It is a practical choice for HVAC installers, pipefitters, and electricians who regularly drill larger-diameter penetrations through metal panels, enclosures, or structural members.

Key Features

• 1-25/64 inch cutting diameter for large-diameter hole work
• High-speed steel (HSS) construction withstands heat generated during metal drilling
• Slow-spiral (SD) flute design reduces chip packing and improves bit control at large diameters
• 1/2-inch shank fits standard 1/2-inch drill chucks without a large-capacity chuck
• Import-grade tooling provides a cost-effective option for intermittent or general-purpose use

Compatibility

Designed for use in any drill press or power drill with a 1/2-inch or larger chuck capacity. Suitable for general-purpose drilling in metals, plastics, and wood composites where a 1-25/64 inch diameter hole is required.

Installation Notes

This bit is installed and removed by a licensed or qualified technician or machinist following standard tooling safety practices. Secure the bit fully in the chuck and verify there is no runout before beginning the cut. Always wear appropriate eye protection and secure the workpiece to prevent rotation. For metal drilling, apply cutting fluid to extend bit life and reduce heat buildup at the cutting edge.
