Eagle Cutting Tool C1080-046-D Cobalt Drill Bit 23/32 in

Product Description

The EAGLE CUTTING TOOL C1080-046-D is a 23/32-inch cobalt screw machine (stub length) drill bit with a 1/2-inch straight shank, manufactured in the USA. Cobalt construction provides superior heat resistance compared to standard high-speed steel, making this bit well suited for drilling through hard and abrasive materials such as stainless steel, cast iron, titanium, and hardened alloys. The screw machine length geometry offers a shorter flute and overall length than a jobber drill, which increases rigidity and reduces deflection in tight-clearance drilling applications. This bit is used by machinists, pipefitters, ironworkers, and maintenance technicians who require precise, repeatable holes in demanding materials.

This drill bit is appropriate for use in drill presses, milling machines, and CNC equipment where a 1/2-inch shank capacity is available. It is also compatible with heavy-duty hand drills equipped with a 1/2-inch chuck. Typical applications include structural steel fabrication, pipe and conduit work, sheet metal shops, and industrial maintenance where standard jobber-length bits lack the necessary rigidity or heat tolerance. The stub length design is particularly effective when working in confined spaces or when extended bit reach is a liability rather than an asset.

Key Features

• 23/32-inch cutting diameter for medium-to-large hole applications
• Cobalt alloy construction resists heat buildup during high-speed or dry drilling
• Screw machine (stub) length increases rigidity and reduces bit deflection
• 1/2-inch straight shank fits standard drill press and heavy-duty hand drill chucks
• Made in the USA

Compatibility

Designed for use in any drill press, milling machine, CNC setup, or heavy-duty hand drill with a 1/2-inch or larger chuck capacity accepting a straight-shank stub-length drill bit.

Installation Notes

Secure the shank fully in the chuck before operation and verify chuck tightness to prevent slippage under torque. Use an appropriate cutting fluid or coolant when drilling hard metals to extend bit life and maintain dimensional accuracy. Always wear proper eye protection and secure the workpiece before drilling. Consult applicable shop safety standards and OSHA general industry guidelines for drill press and hand-drill operation.
