Eagle Cutting Tool C1090-046-I Cobalt Drill Bit 23/32 in

Product Description

The EAGLE CUTTING TOOL C1090-046-I is a 23/32-inch cobalt screw machine (stub length) drill bit with a 1/2-inch straight shank. Cobalt construction provides increased heat resistance and hardness compared to standard high-speed steel, making this bit well-suited for drilling tough materials including stainless steel, cast iron, and hardened alloys. The stub-length body reduces deflection and improves hole accuracy in tight workspaces or when using drill presses and milling machines. This bit is a practical choice for machinists, pipefitters, plumbers, and HVAC technicians who regularly drill through hard metals in the field or shop.

This drill bit is appropriate for use in general metalworking, fabrication, mechanical contracting, and maintenance applications where a durable, large-diameter hole is required. The 1/2-inch shank fits standard 1/2-inch keyed or keyless chucks found on drill presses, magnetic drills, and heavy-duty hand drills. It is commonly used in residential and commercial mechanical rooms, fabrication shops, and job-site installations where consistent, clean holes in metal are required.

Key Features

• Cobalt construction for improved heat resistance and durability when drilling hard metals
• 23/32-inch cutting diameter for large-bore hole applications
• 1/2-inch straight shank fits standard drill press and heavy-duty hand drill chucks
• Stub-length screw machine geometry reduces deflection and improves drilling accuracy
• Suitable for stainless steel, cast iron, hardened alloys, and similar difficult materials

Compatibility

Designed as a replacement or additional drill bit for any setup accepting a 1/2-inch straight shank, including standard drill presses, magnetic base drills, and heavy-duty hand drills used in metalworking and mechanical contracting applications.

Installation Notes

This bit is installed and operated by machinists, pipefitters, electricians, and mechanical contractors. Secure the shank fully in the chuck before drilling and verify chuck key is removed prior to operation. Use appropriate cutting fluid when drilling hard metals to extend bit life and reduce heat buildup. Always wear eye protection and secure the workpiece before drilling.
