Eagle Cutting Tool 1080-059-D Hss Drill Bit 59/64 in

Product Description

The EAGLE CUTTING TOOL 1080-059-D is a 59/64-inch high-speed steel (HSS) screw machine drill bit with a 1/2-inch reduced shank, manufactured in the USA. Screw machine length drill bits feature a shorter flute and overall length compared to jobber-length bits, which improves rigidity and reduces deflection in high-cycle production drilling environments. This bit is suited for use in drill presses, CNC machining centers, and manual lathes where a stubby, rigid cutting tool is required. HSS construction provides adequate hardness and heat resistance for drilling steel, aluminum, cast iron, brass, and similar materials at standard cutting speeds.

This drill bit is intended for trade and industrial use in machining, fabrication, and maintenance applications. The 1/2-inch shank makes it compatible with standard 1/2-inch drill chucks and collet holders common in machine shop and production environments. It is well suited for metalworking professionals, maintenance machinists, and fabricators who require consistent hole quality in metal stock, plate, or structural material.

Key Features

• 59/64-inch cutting diameter in screw machine (stub) length for improved rigidity
• High-speed steel (HSS) construction for durability across a range of metal types
• 1/2-inch reduced shank for compatibility with standard drill chucks and collet systems
• Made in the USA
• Minimum order quantity of 1 unit — available as a single bit

Compatibility

Designed for use in standard 1/2-inch drill chucks, machine tool collets, and compatible drill press or CNC spindle setups where screw machine length HSS drill bits are specified.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or metalworking tradespeople. Always secure the shank fully in the chuck or collet and verify runout before drilling. Power down and lock out the machine before changing tooling. Follow applicable shop safety procedures and use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality.
