Eagle Cutting Tool C300-023-D Cobalt Jobber Drill 23/64

Product Description

The EAGLE CUTTING TOOL C300-023-D is a 23/64 inch cobalt jobber-length drill bit manufactured in the USA. Cobalt construction provides superior heat resistance and edge retention compared to standard high-speed steel, making this bit well suited for drilling into harder materials including stainless steel, cast iron, hard alloys, and high-strength metals. The jobber-length geometry offers a balanced combination of reach and rigidity for general-purpose drilling across a wide range of trade and industrial applications. Electricians, plumbers, HVAC technicians, and fabricators rely on cobalt jobber drills for through-hole work in structural and mechanical assemblies.

This drill bit is used in both residential and commercial trade applications where standard HSS bits fail to hold an edge. Typical install scenarios include drilling anchor holes in structural steel, creating conduit and pipe penetrations through hard metal framing members, and boring holes in equipment panels or mounting plates. Its 23/64 inch diameter is a common size for clearance holes and pilot work in heavier-gauge metal components.

Key Features

• Cobalt construction for increased heat resistance and extended tool life in hard metals
• 23/64 inch jobber-length geometry balances reach and rigidity
• USA manufactured
• Suitable for drilling stainless steel, cast iron, hard alloys, and high-strength materials
• General-purpose jobber length fits standard drill chucks and magnetic drill presses

Compatibility

Designed as a general-purpose cobalt jobber drill bit compatible with standard 3-jaw drill chucks and drill presses accepting round-shank bits in the 23/64 inch size.

Installation Notes

Cobalt drill bits should be used with cutting fluid or coolant when drilling hard metals to maximize tool life and prevent work hardening. Secure the workpiece firmly before drilling and use consistent, moderate feed pressure to avoid bit deflection or breakage. Always wear appropriate eye protection and follow applicable shop safety standards when operating power drilling equipment.
