Eagle Cutting Tool C304-145-D 45 Cobalt Jobber Drill

Product Description

The EAGLE CUTTING TOOL C304-145-D is a cobalt jobber-length drill bit sized at 45, designed for drilling through hard and abrasive materials where standard high-speed steel bits fall short. Cobalt construction provides elevated heat resistance and edge retention, making it well suited for sustained use in ferrous metals, stainless steel, cast iron, and high-strength alloys. At 0.12 pounds, this is a lightweight, single-piece cutting tool intended for use in drill presses, hand drills, and CNC setups across industrial and trade environments. It is manufactured in the USA.

This jobber drill is used in metal fabrication shops, mechanical contracting, and general industrial maintenance wherever a reliable cobalt bit is needed for demanding materials. The jobber-length geometry provides a balance of reach and rigidity that suits most standard drilling applications. It is appropriate for machinists, pipefitters, electricians, and maintenance technicians working with harder base materials that would wear a standard twist drill prematurely.

Key Features

• Cobalt construction for superior heat resistance and longer edge life in hard metals
• Jobber-length design balances reach and rigidity for general-purpose drilling
• Manufactured in the USA
• Lightweight at 0.12 pounds for easy handling and tool-holder compatibility
• Minimum order quantity of 1, available as a single unit

Compatibility

Designed as a standard jobber-length cobalt drill bit suitable for use in 3-jaw chucks, keyed chucks, and collet-style tool holders compatible with its shank diameter.

Installation Notes

Installation is performed by machinists and trade professionals familiar with rotating cutting tools. Secure the bit firmly in the chuck and verify runout before drilling. Always wear appropriate eye protection and follow shop safety protocols when operating drilling equipment. Reduce feed rate and use cutting fluid when drilling stainless steel or other work-hardening alloys to extend bit life.
