Eagle Cutting Tool 1080-057-D Hss Stub Drill Bit 57/64 in

Product Description

The EAGLE CUTTING TOOL 1080-057-D is a 57/64-inch high-speed steel (HSS) stub drill bit with a 1/2-inch straight shank. Stub-length geometry reduces deflection and improves rigidity compared to jobber-length bits, making it well suited for drilling in tight spaces or through thick stock where a shorter flute length provides better control. Manufactured in the USA, this bit is built for production-shop and job-site use by machinists, pipefitters, ironworkers, and trade professionals who need reliable, repeatable hole geometry in ferrous and non-ferrous materials.

The 1080-057-D is used in general metalworking, fabrication, and maintenance applications where a near-one-inch bore is required. The 1/2-inch shank fits standard 1/2-inch drill chucks found on heavy-duty corded drills, drill presses, and milling machine spindles. Its stub design is commonly chosen when working in confined areas, through structural steel, thick plate, or flange stock where a full-length bit would chatter or wander.

Key Features

• 57/64-inch cutting diameter for close-tolerance near-1-inch hole applications
• High-speed steel (HSS) construction handles heat generated during heavy-duty metal drilling
• Stub-length flute reduces deflection and improves hole accuracy in thick materials
• 1/2-inch straight shank for compatibility with standard heavy-duty drill chucks
• USA manufactured

Compatibility

Designed as a direct-fit stub drill bit for any drill press, corded drill, or milling machine equipped with a 1/2-inch chuck. Verify spindle speed recommendations for the target material before use.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or trade professional familiar with cutting tool safety. Secure the shank fully in the chuck and verify the bit runs true before engaging the workpiece. Always wear appropriate eye protection and secure the workpiece with clamps or a vise — never hand-hold metal stock during drilling. Follow the drill press or machine manufacturer's guidelines for appropriate spindle RPM based on material type and bit diameter.
