Eagle Cutting Tool 1090-057-I Hss Drill Bit 57/64 in

Product Description

The EAGLE CUTTING TOOL 1090-057-I is a 57/64-inch high speed steel (HSS) screw machine (stub length) drill bit with a 1/2-inch reduced shank. Stub length geometry provides greater rigidity and reduced deflection compared to jobber-length bits, making it well suited for drilling in tight spaces or on materials that demand a stiff, accurate cut. The 1/2-inch shank allows the bit to be chucked in standard 1/2-inch drill chucks and most drill presses. This is an import-grade bit appropriate for general production drilling, fabrication shops, and maintenance applications.

This drill bit is used in metalworking, fabrication, and general industrial or maintenance environments. Screw machine drill bits are commonly found in production shops where rigidity and hole accuracy matter more than extended reach. The 57/64-inch diameter is a common sizing used when preparing holes for reaming, tapping, or close-tolerance fastener clearances. Licensed tradespeople and shop machinists working with steel, aluminum, cast iron, and similar materials will find this bit a practical stock item.

Installation Notes

A licensed machinist or qualified shop technician should ensure the chuck or collet is fully tightened and the bit is seated true before operation. Always secure the workpiece with appropriate clamping before drilling. Operate at feed rates and spindle speeds appropriate for the workpiece material and bit diameter per standard machining references. Wear appropriate eye and hand protection in accordance with applicable shop safety standards.
