Eagle Cutting Tool C1080-054-D Cobalt Drill Bit 27/32 in

Product Description

The EAGLE CUTTING TOOL C1080-054-D is a 27/32-inch cobalt screw machine (stub length) drill bit with a 1/2-inch reduced shank, manufactured in the USA. Cobalt high-speed steel construction provides superior heat and wear resistance compared to standard HSS, making this bit well suited for drilling hard and abrasive materials including stainless steel, cast iron, titanium, and hardened alloys. The stub-length body offers increased rigidity and reduced deflection in demanding production and maintenance drilling applications. Licensed trades and machinists reach for cobalt stub drills when hole quality and bit longevity matter on tough materials.

This drill bit is designed for use in machine shops, fabrication facilities, and field maintenance environments where hard metals are regularly encountered. The 1/2-inch shank allows it to seat directly in standard 1/2-inch or larger drill chucks and drill press spindles without a reduction sleeve. Typical applications include metal fabrication, structural steel work, HVAC equipment fabrication, plumbing rough-in through metal framing, and electrical panel or enclosure drilling. The stub-length geometry keeps the cutting edge close to the chuck for maximum control in drill press and handheld power drill setups.

Key Features

• 27/32-inch cutting diameter for precise, full-size holes in metal
• Cobalt high-speed steel construction resists heat buildup and edge wear on hard materials
• Stub-length screw machine body provides rigidity and minimizes bit deflection
• 1/2-inch reduced shank fits standard drill chucks and press spindles without adapters
• USA manufactured for consistent dimensional accuracy and quality control

Compatibility

Designed for use in any drill press, CNC drill, or handheld drill accepting a 1/2-inch or larger chuck. Compatible with standard drill press spindles and machine tool holders sized for 1/2-inch shank tooling.

Installation Notes

Secure the shank fully in the chuck and verify the bit runs true before engaging the workpiece. Use a cutting fluid or coolant appropriate for the workpiece material to extend cutting edge life when drilling hard metals. Always secure the workpiece firmly in a vise or fixture — never hand-hold metal stock being drilled. Wear appropriate eye protection and follow applicable shop safety practices.
