Eagle Cutting Tool C304-144-D Cobalt Jobber No. 44

Product Description

The EAGLE CUTTING TOOL C304-144-D is a No. 44 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction provides elevated heat resistance and hardness compared to standard high-speed steel, making this bit suitable for drilling into harder materials such as stainless steel, cast iron, and high-strength alloys. The jobber-length geometry delivers a balance of reach and rigidity for general-purpose drilling in production and maintenance applications. Machinists, pipefitters, and electricians commonly reach for cobalt jobber drills when standard HSS bits fail to hold an edge under heavy-duty conditions.

This bit is suited for use in drill presses, hand drills, and CNC drilling operations where a No. 44 diameter hole is required. Typical applications include pilot holes, clearance holes, and through-holes in metal fabrication, mechanical assembly, and field service work. The USA manufacturing designation indicates domestic production, which is a common specification requirement on government and industrial contracts.

Key Features

• Cobalt construction for improved heat resistance and extended tool life in hard metals
• No. 44 wire gauge size for precision small-diameter drilling
• Jobber-length geometry balances reach and rigidity
• Manufactured in the USA
• Minimum order quantity of 1 unit

Compatibility

Designed as a standard jobber-length drill bit compatible with conventional drill chucks and collet holders accepting No. 44 wire gauge shank diameters in hand drills, drill presses, and CNC equipment.

Installation Notes

Secure the bit fully in the chuck or collet before operation and confirm there is no runout. Use appropriate cutting fluid when drilling hardened or stainless materials to extend bit life and maintain hole quality. Wear eye protection and secure the workpiece properly. Dispose of worn bits per shop safety protocols.
