Eagle Cutting Tool C300-005-D Cobalt Jobber Drill 5/64

Product Description

The EAGLE CUTTING TOOL C300-005-D is a 5/64-inch cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit the heat resistance and hardness needed to cut through tough materials including stainless steel, cast iron, and hard alloys. The jobber-length configuration provides a balanced combination of reach and rigidity, making it a reliable choice for production drilling and general metalworking applications. It is used by machinists, pipefitters, electricians, HVAC technicians, and other trade professionals who regularly drill into hard or abrasive materials.

This drill bit is suited for use in hand-held drills, drill presses, and CNC equipment where a small-diameter, high-durability bit is required. The 5/64-inch diameter makes it appropriate for pilot holes, tapping pre-drill operations, and light-gauge metal fabrication. Domestic manufacture supports consistent quality control and dimensional accuracy across the product line.

Key Features

• Cobalt construction for superior heat resistance and hardness when drilling tough alloys
• 5/64-inch diameter for precision small-hole drilling and pilot hole applications
• Jobber-length design balances reach and rigidity for general-purpose use
• Made in the USA for consistent dimensional accuracy
• Minimum order quantity of 1 for flexible purchasing

Compatibility

Designed as an OEM-style replacement and standard jobber drill bit compatible with 3-jaw chucks and standard drill presses, hand drills, and CNC spindles accepting 5/64-inch round-shank tooling.

Installation Notes

Secure the bit firmly in a properly sized chuck before operation and verify chuck jaws are fully tightened to prevent slippage. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and reduce heat buildup. Allow the bit to cool between extended drilling cycles to prevent premature wear. Follow applicable shop safety standards including eye protection and workpiece clamping.
