Eagle Cutting Tool 1090-037-I Hss Drill Bit 37/64 in

Product Description

The EAGLE CUTTING TOOL 1090-037-I is a 37/64-inch high-speed steel (HSS) screw machine (stub) length drill bit with a 1/2-inch shank. Stub-length geometry provides increased rigidity compared to jobber-length bits, reducing deflection and chatter in production drilling applications. The 1/2-inch shank fits standard drill chucks and collet holders used in drill presses, lathes, and CNC equipment. HSS construction offers good hardness and wear resistance for drilling through mild steel, aluminum, brass, and similar materials. This bit is suited for machinists, tool-and-die technicians, and shop professionals who need a reliable, compact drill for repetitive or precision hole work.

The 1090-037-I is appropriate for use in machine shop environments, production lines, and maintenance operations requiring consistent 37/64-inch hole diameters. Its stub-length design makes it a practical choice for drilling in confined clearances or on drill press setups where minimal overhang and maximum stability are priorities. The 1/2-inch shank accommodates a wide range of industrial drill chucks without a reducer sleeve.

Key Features

• 37/64-inch cutting diameter for precise hole sizing
• High-speed steel (HSS) construction for hardness and wear resistance
• Stub screw machine length for increased rigidity and reduced deflection
• 1/2-inch straight shank compatible with standard drill chucks and collet holders
• Suited for drilling mild steel, aluminum, brass, and comparable materials

Compatibility

Designed as a standard HSS screw machine drill bit for use with 1/2-inch capacity or larger drill chucks on drill presses, lathes, milling machines, and CNC machining centers.

Installation Notes

Secure the shank fully in the chuck and tighten all jaws before operation. Ensure the spindle and machine are powered down and at a full stop before changing bits. Use appropriate cutting fluid for the material being drilled to extend tool life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace the bit if edges are dull or damaged.
