Eagle Cutting Tool C1080-053-D Cobalt Drill Bit 53/64 in

Product Description

The EAGLE CUTTING TOOL C1080-053-D is a 53/64 inch cobalt screw machine (stub-length) drill bit with a 1/2 inch reduced shank. Cobalt construction gives the bit superior heat resistance compared to standard high-speed steel, making it well suited for drilling hard or abrasive materials where friction and heat build quickly. The stub-length body provides added rigidity and reduced deflection, which translates to more accurate hole placement and longer tool life in production or repetitive drilling applications. Manufactured in the USA, this bit is built to consistent tolerances expected in professional trade and machining environments.

The C1080-053-D is designed for use in metalworking, fabrication, HVAC rough-in, mechanical contracting, and industrial maintenance applications where a 53/64 inch hole is required in ferrous or non-ferrous metals, stainless steel, or other hard materials. The 1/2 inch reduced shank allows the bit to be chucked in standard 1/2 inch drill chucks or drill presses without requiring a larger chuck size for the full 53/64 inch body diameter. It is appropriate for both floor-model drill press work and heavy-duty hand drill use by experienced tradespeople.

Key Features

• 53/64 inch diameter cobalt construction for drilling hard metals and abrasive materials
• Stub-length screw machine body provides increased rigidity and reduced bit deflection
• 1/2 inch reduced shank fits standard 1/2 inch drill chucks without adapter
• Cobalt alloy offers improved heat resistance over standard HSS bits, extending tool life in high-friction cuts
• Made in the USA to consistent dimensional tolerances

Compatibility

Designed as a screw machine stub-length drill bit compatible with any drill press or heavy-duty hand drill equipped with a 1/2 inch or larger chuck.

Installation Notes

Secure the 1/2 inch shank firmly in a properly rated drill chuck before use, and verify the chuck is fully tightened to prevent slippage under load. Always use appropriate cutting fluid or coolant when drilling hard metals to protect both the bit and the workpiece. Wear appropriate PPE including eye protection and secure loose clothing before operating any drilling equipment. Follow applicable OSHA and shop safety guidelines for rotating tool operation.
