Eagle Cutting Tool C304-138-D Cobalt Jobber Drill

Product Description

The EAGLE CUTTING TOOL C304-138-D is a cobalt jobber-length drill bit manufactured in the USA. Cobalt construction provides increased heat resistance and hardness compared to standard high-speed steel, making this bit well suited for drilling through tough materials such as stainless steel, cast iron, and hardened alloys. At 0.12 pounds, it is a lightweight, single-piece cutting tool designed for use in standard drill chucks. Electricians, pipefitters, HVAC technicians, and general trade contractors reach for cobalt jobber drills when standard twist bits wear prematurely on hard substrates.

This bit fits common jobber-length applications in both residential and commercial trade work. Typical use cases include drilling through structural steel, equipment housings, sheet metal, and piping flanges. The jobber-length profile balances reach and rigidity, making it practical for handheld drills, drill presses, and magnetic base drills. It is a USA-manufactured bit appropriate for shop use and field service work where cutting performance and durability under heat are priorities.

Key Features

• Cobalt steel construction for superior heat resistance and extended tool life on hard materials
• Jobber-length profile balances cutting reach with lateral rigidity
• USA manufactured for consistent dimensional tolerancing and material quality
• Compatible with standard drill chucks used on corded and cordless drill platforms
• Lightweight at 0.12 pounds for easy single-hand handling and tool bag portability

Compatibility

Designed as a jobber-length cobalt drill bit suitable for use in standard keyed and keyless drill chucks across corded drills, cordless drills, and drill press applications in trade and industrial settings.

Installation Notes

Ensure the drill chuck is fully tightened and the bit is seated straight before starting any drilling operation. Use appropriate cutting fluid or lubricant when drilling through stainless steel or hardened alloys to prolong bit life and reduce heat buildup. Always wear appropriate eye and hand protection per applicable jobsite safety requirements. Secure the workpiece firmly before drilling to prevent movement and bit breakage.
