Eagle Cutting Tool C304-113-D Cobalt Jobber Drill

Product Description

The EAGLE CUTTING TOOL C304-113-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 drill suitable for demanding materials including stainless steel, cast iron, hard alloys, and other tough metals. The jobber-length design offers the standard reach-to-diameter ratio used across general-purpose drilling applications in mechanical, HVAC, plumbing, and electrical trade work. This drill is installed and used by trade professionals who require consistent, reliable performance in metal fabrication and field drilling tasks.

The C304-113-D is suited for use in hand-held drill motors, drill presses, and magnetic-base drills. It is a general-purpose jobber drill appropriate for both shop and field environments where hard or abrasive metals are commonly encountered. Tradespeople drilling sheet metal, structural steel, copper pipe fittings, or electrical enclosures will find this bit appropriate for those substrates. It is sized as a number 13 drill, which corresponds to a fractional size used in standard drilling and tapping operations.

Key Features

• Cobalt construction for improved heat and wear resistance over standard HSS bits
• Jobber-length geometry provides a balanced reach suitable for general-purpose metal drilling
• USA manufactured for consistent dimensional tolerances and quality control
• Compatible with standard drill chucks used in hand drills and drill presses
• Suitable for drilling ferrous and non-ferrous hard metals

Compatibility

Designed as a general-purpose cobalt jobber drill for use in standard three-jaw chucks on portable drills, drill presses, and magnetic-base drilling equipment across HVAC, plumbing, electrical, and mechanical trade applications.

Installation Notes

Secure the drill bit firmly in the chuck before operation and verify concentricity to avoid bit deflection. Use cutting fluid or coolant when drilling hard metals to extend bit life and reduce heat buildup. Reduce feed pressure as the drill breaks through the workpiece to prevent bit grabbing or breakage. Always wear appropriate eye protection and follow applicable shop safety practices.
