Eagle Cutting Tool C304-104-D Cobalt Jobber Drill

Product Description

The EAGLE CUTTING TOOL C304-104-D is a cobalt jobber-length drill designed for demanding metalworking and fabrication applications. Cobalt construction provides superior heat resistance compared to standard high-speed steel, making it well suited for drilling hard alloys, stainless steel, cast iron, and other tough materials. Manufactured in the USA, this drill is built to handle production environments where bit longevity and consistent hole quality matter. It is a standard jobber-length configuration, offering a balanced reach-to-rigidity ratio appropriate for most bench and floor drill press work as well as handheld operations.

This drill is used across mechanical, HVAC, plumbing, and electrical trades wherever metal drilling is required on the job site or in a shop setting. Typical applications include drilling through structural steel, pipe, conduit, junction boxes, and equipment frames. Its cobalt composition makes it a preferred choice when working with harder base metals or when extended run times cause standard bits to dull prematurely.

Key Features

• Cobalt construction for enhanced heat and wear resistance during high-speed drilling
• Jobber-length design balances reach and rigidity for general-purpose metal drilling
• USA manufactured for consistent dimensional tolerances and material quality
• Compatible with standard drill presses, handheld drills, and magnetic base drills

Compatibility

Designed as a general-purpose cobalt jobber drill suitable for use in standard three-jaw drill chucks across a wide range of drill presses and handheld drill drivers.

Installation Notes

Cobalt jobber drills are installed and operated by machinists, pipefitters, electricians, and general tradespeople. Secure the bit fully in the chuck and verify it runs true before cutting. Use appropriate cutting fluid or lubricant when drilling hard alloys to extend bit life and improve cut quality. Wear eye protection and secure workpieces properly to prevent movement during drilling.
