Eagle Cutting Tool C1080-050-D Cobalt Drill Bit 25/32 in

Product Description

The EAGLE CUTTING TOOL C1080-050-D is a 25/32-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 and edge retention compared to standard high-speed steel, making this bit well suited for drilling hard and abrasive materials including stainless steel, cast iron, titanium, and hardened alloys. The stub-length body is shorter than a jobber drill, reducing deflection and increasing rigidity in tight-clearance applications. Machinists, pipefitters, and fabricators rely on this style of bit for production drilling where hole accuracy and tool longevity are priorities.

This drill bit is designed for use in drill presses, milling machines, and CNC machining centers where a 1/2-inch chuck or collet is available. The stub-length design makes it a practical choice for sheet metal fabrication shops, machine shops, and mechanical contractors drilling through structural materials. It is equally useful in maintenance and repair operations where a rigid, durable bit is needed for occasional heavy-material work.

Key Features

• 25/32-inch diameter cobalt construction for heat resistance and long tool life
• Stub length (screw machine) body reduces deflection for more accurate holes
• 1/2-inch straight shank fits standard 1/2-inch chucks and collets
• Suited for hard and abrasive materials including stainless steel and cast iron
• Made in the USA

Compatibility

Designed as an OEM-style replacement or direct fitment for any drill press, milling machine, or machining center equipped with a 1/2-inch chuck or collet accepting a straight-shank stub-length drill bit.

Installation Notes

This bit is installed by a machinist or qualified tradesperson into a 1/2-inch drill chuck or collet. Secure the shank fully and verify chuck tightness before operation. Use appropriate cutting fluid or coolant for hard-material applications to preserve edge life. Always wear appropriate eye protection and follow applicable shop safety standards when operating drilling equipment.
