Eagle Cutting Tool 1090-053-I Hss Drill Bit 53/64 in

Product Description

The EAGLE CUTTING TOOL 1090-053-I is a 53/64-inch high speed steel (HSS) screw machine (stub length) drill bit with a 1/2-inch straight shank. Screw machine length drills are shorter than jobber-length bits, providing increased rigidity and reduced deflection when drilling in metal, plastics, and other industrial materials. The HSS construction handles the heat generated during high-speed drilling operations. This bit is used by machinists, pipefitters, maintenance technicians, and industrial tradespeople who need a stiff, accurate drill for close-tolerance work in drill presses, lathes, and CNC setups.

Screw machine drill bits are a standard choice for production and maintenance environments where hole accuracy and bit longevity matter. The 1/2-inch shank fits standard 1/2-inch drill chucks and collet holders common on benchtop and floor-mounted drill presses. The 53/64-inch diameter is suited for applications requiring a precisely sized hole before reaming or tapping, or where a close-fit clearance hole is needed for fasteners and fittings in metal fabrication and mechanical assembly work.

Key Features

• 53/64-inch cutting diameter for close-tolerance hole sizing
• High speed steel construction resists heat buildup during drilling
• Stub screw machine length provides greater rigidity and reduced deflection versus jobber-length bits
• 1/2-inch straight shank fits standard drill chucks and collet holders
• Suitable for drilling metal, plastics, and similar industrial materials

Compatibility

Designed as a standard screw machine length HSS drill bit compatible with any 1/2-inch capacity drill chuck on drill presses, lathes, and CNC machine tools.

Installation Notes

This bit is installed and used by machinists and industrial tradespeople. Secure the shank fully in a properly tightened chuck before operating. Use appropriate cutting fluid for the material being drilled to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use and replace if the bit shows signs of dullness or damage.
