Eagle Cutting Tool 1080-039-D 39/64 Hss Drill Bit

Product Description

The EAGLE CUTTING TOOL 1080-039-D is a 39/64-inch high-speed steel (HSS) screw machine drill bit with a 1/2-inch reduced shank. Screw machine length drill bits are shorter and more rigid than jobber-length bits, making them well suited for drilling in confined spaces where chatter and deflection need to be minimized. The 1/2-inch shank allows the bit to seat securely in standard 1/2-inch drill chucks and magnetic drill press adapters. This bit is manufactured in the USA, indicating domestic production standards for HSS tooling used in metal fabrication and mechanical trades.

This drill bit is appropriate for drilling ferrous and non-ferrous metals including mild steel, aluminum, and brass in production, maintenance, and repair environments. The screw machine length profile makes it a practical choice for drill press work, CNC turret applications, and hand drilling in tight clearance areas. It is commonly used by machinists, pipefitters, ironworkers, and maintenance mechanics requiring a short, stiff bit in a common chuck size.

Key Features

• 39/64-inch diameter for precise hole sizing in metal fabrication
• High-speed steel (HSS) construction for durability across a range of metals
• Screw machine length body provides increased rigidity and reduced deflection
• 1/2-inch shank fits standard 1/2-inch drill chucks and adapters
• USA manufactured

Compatibility

Designed for use in any drill press, magnetic drill, or hand drill equipped with a 1/2-inch or larger chuck accepting a 1/2-inch straight shank bit.

Installation Notes

Secure the shank fully in the chuck before operation and verify chuck key is removed prior to starting the drill. Use appropriate cutting fluid or lubricant when drilling steel to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and discontinue use if the bit shows signs of chipping or excessive wear. This tooling is intended for use by trained machinists and trade professionals familiar with safe drilling practices.
