Eagle Cutting Tool C300-027-D Cobalt Jobber 27/64 in

Product Description

The EAGLE CUTTING TOOL C300-027-D is a 27/64-inch cobalt jobber-length drill bit made in the USA. Cobalt construction gives this bit the heat resistance and hardness needed to cut through stainless steel, hardened alloys, cast iron, and other tough materials that standard high-speed steel bits struggle with. The jobber-length flute profile balances reach and rigidity for general-purpose drilling across a wide range of applications. It is the go-to choice for machinists, pipefitters, electricians, HVAC technicians, and plumbers who regularly drill through hard metals on the job.

This drill bit fits standard drill chucks and magnetic drill presses used in trade and light industrial settings. The 27/64-inch diameter is commonly used for tap drilling, clearance holes, and conduit or pipe work where a precise, slightly undersized or oversized hole is required. Suitable for use in both stationary drill presses and portable hand drills where cobalt-grade performance is needed in the field or shop.

Compatibility

Designed for use in standard 3-jaw drill chucks and magnetic drill presses accepting jobber-length bits. Compatible with applications requiring a 27/64-inch diameter hole in steel, stainless steel, cast iron, and similar hard materials.

Installation Notes

Cobalt drill bits are installed and operated by machinists, pipefitters, and trade professionals using standard drill presses or portable drills. Secure the bit firmly in the chuck before use and verify the workpiece is clamped or secured to prevent movement. Use appropriate cutting fluid when drilling hard metals to extend bit life and maintain hole quality. Follow applicable shop safety protocols and wear eye protection at all times during drilling operations.
