Eagle Cutting Tool C304-111-D Cobalt Jobber Drill Bit

Product Description

The EAGLE CUTTING TOOL C304-111-D is a cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit the heat and wear resistance needed for drilling through hard metals, stainless steel, cast iron, and other tough materials that would quickly degrade a standard high-speed steel bit. At 0.42 pounds, it is a solid, full-size jobber bit suited for use in standard drill presses, magnetic drills, and hand drills. Electricians, plumbers, HVAC technicians, and general tradespeople reach for cobalt jobber bits when working through structural steel, pipe, unistrut, and equipment enclosures.

This bit is appropriate for both shop and field use wherever a durable, standard-length drilling solution is required. The jobber-length geometry balances reach and rigidity, making it a versatile choice across residential, commercial, and light industrial applications. Its USA manufacture indicates adherence to domestic tolerances and material standards, which matters on jobs where dimensional accuracy and bit longevity are critical to workflow.

Key Features

• Cobalt construction for superior heat resistance when drilling hard metals
• Jobber-length design balances reach with torsional rigidity
• USA manufactured to domestic dimensional and material standards
• Suitable for use in drill presses, magnetic drills, and standard hand drills
• Lightweight at 0.42 pounds for easy transport and field use

Compatibility

Designed as a standard jobber-length cobalt drill bit compatible with conventional drill chucks accepting standard straight-shank bits.

Installation Notes

Cobalt drill bits should be installed in the drill chuck securely and centered before operation. Use cutting fluid or lubricant when drilling through hard metals to extend bit life and maintain cutting edge integrity. Allow the bit to do the work at appropriate feed pressure — excessive force can cause bit breakage or premature wear. This bit should be handled and stored carefully to protect the cutting edges.
