Eagle Cutting Tool C304-127-D Cobalt Jobber Drill No. 27

Product Description

The EAGLE CUTTING TOOL C304-127-D is a No. 27 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit greater heat resistance and edge retention compared to standard high-speed steel, making it well suited for drilling harder metals such as stainless steel, cast iron, and heat-treated alloys. The jobber-length geometry provides a balance of reach and rigidity for general-purpose drilling in production and maintenance environments. At 0.42 pounds, this is a single-bit offering sized for standard drill chucks used across trades and machining applications.

This drill bit is used in metalworking, mechanical, HVAC, and plumbing trade applications where a No. 27 diameter hole is required. Typical uses include tap pilot holes, sheet metal, structural steel, and equipment fabrication. The cobalt composition makes it appropriate for job sites and shops where abrasive or work-hardening materials are encountered regularly. It is equally at home in a hand drill, drill press, or CNC setup.

Key Features

• Minimum order quantity of 1, available as a single unit

Compatibility

Designed as a general-purpose No. 27 cobalt jobber drill suitable for use in standard keyed and keyless drill chucks on hand drills, drill presses, and machine tools that accept jobber-length round-shank bits.

Installation Notes

Drill bits of this type are installed and removed by licensed machinists, maintenance technicians, and trade professionals using standard chuck keys or keyless chuck mechanisms. Always ensure the drill or press is fully powered down and the chuck is secure before beginning work. Use appropriate cutting fluid when drilling hard or stainless alloys to preserve edge life. Wear appropriate eye protection and secure the workpiece before drilling.
