Eagle Cutting Tool C304-105-D Cobalt Jobber Drill Size 5

Product Description

The EAGLE CUTTING TOOL C304-105-D is a size 5 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit the heat resistance and hardness needed to cut through tough materials including stainless steel, hardened alloys, cast iron, and high-tensile metals. The jobber-length geometry provides a balance of reach and rigidity suited to general-purpose drilling across a wide range of applications. This bit is used by machinists, pipefitters, plumbers, electricians, and other trade professionals who need reliable hole-making performance in demanding materials.

This drill bit is suited for use in machine shops, fabrication facilities, and field service environments where standard jobber-length tooling is required. The cobalt composition makes it appropriate for production drilling and repeat-use applications where standard high-speed steel bits wear prematurely. It fits standard drill chucks and can be used in drill presses, magnetic drills, and hand drills.

Key Features

• Cobalt construction for improved heat resistance and extended tool life in hard materials
• Jobber-length geometry balances reach and rigidity for general-purpose drilling
• Size 5 wire gauge designation for precise hole sizing
• USA manufactured
• Minimum order quantity of 1 for single-piece purchasing flexibility

Compatibility

Designed as a general-purpose cobalt jobber drill bit compatible with standard drill chucks used in drill presses, magnetic base drills, and portable hand drills across trade and industrial applications.

Installation Notes

Cobalt drill bits should be installed securely in a properly sized chuck before use. Use appropriate cutting fluid or coolant when drilling hard metals to prolong bit life and reduce heat buildup. Ensure the workpiece is firmly clamped or secured before drilling. Inspect the cutting edges for wear or chipping before each use and replace as needed to maintain hole quality.
