Eagle Cutting Tool C1080-047-D Cobalt Drill Bit 47/64 in

Product Description

The EAGLE CUTTING TOOL C1080-047-D is a 47/64 inch cobalt screw machine (stub length) drill bit with a 1/2 inch reduced shank, manufactured in the USA. Cobalt construction provides superior heat resistance and edge retention compared to standard high-speed steel, making this drill bit well suited for cutting through hard and abrasive materials. The screw machine length profile offers a shorter, stiffer geometry than jobber-length bits, reducing deflection and improving hole accuracy in production and maintenance drilling applications.

This drill bit is used in metalworking, fabrication, and maintenance environments where a rigid, heat-tolerant cutting tool is required. The 1/2 inch reduced shank allows it to seat in standard 1/2 inch drill chucks and milling machine holders without requiring a larger spindle bore. Typical applications include drilling steel, stainless steel, cast iron, and other ferrous materials in shop or field settings. It is appropriate for both manual drill press use and CNC drilling operations where a stub-length bit is specified.

Key Features

• 47/64 inch cutting diameter in a stub-length screw machine geometry for reduced deflection
• Cobalt alloy construction for extended tool life in hard and heat-generating materials
• 1/2 inch reduced shank fits standard 1/2 inch chucks and tool holders
• Manufactured in the USA
• Minimum order quantity of 1 unit

Compatibility

Designed as an OEM-style replacement or direct-use stub drill for standard 1/2 inch drill chucks, drill presses, and compatible CNC spindles requiring a 47/64 inch screw machine length drill bit.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with metal cutting operations. Ensure the drill chuck or collet is fully tightened and the workpiece is properly secured before beginning any drilling operation. Use appropriate cutting fluid for the material being drilled to maximize bit life and reduce heat buildup. Always wear appropriate eye protection and follow applicable shop safety procedures.
