Eagle Cutting Tool C300-015-D Cobalt Jobber Drill 15/64

Product Description

The EAGLE CUTTING TOOL C300-015-D is a cobalt jobber-length twist drill bit sized at 15/64 inch. Cobalt high-speed steel construction gives this bit the heat resistance needed to cut through hard metals, stainless steel, cast iron, and other abrasive materials without premature edge breakdown. The jobber-length flute geometry provides a practical balance of reach and rigidity, making it a standard choice for general-purpose drilling in fabrication, maintenance, and mechanical service work. Electricians, pipefitters, millwrights, and HVAC technicians reach for cobalt bits when standard HSS bits fail to hold an edge on harder base materials.

This bit is suited for use in hand drills, drill presses, and magnetic base drills across residential, commercial, and light industrial applications. Common tasks include drilling pilot holes in structural steel, drilling access holes through heavy-gauge sheet metal, and enlarging existing holes in ferrous and non-ferrous workpieces. The 15/64 inch diameter fits standard drill chucks without adapters. Manufactured in the USA.

Compatibility

Designed as a general-purpose cobalt jobber drill compatible with standard 3/8 inch and 1/2 inch keyed or keyless drill chucks used in hand drills and drill presses.

Installation Notes

A licensed machinist, pipefitter, electrician, or experienced mechanical technician typically selects and installs drill bits as part of standard drilling operations. Secure the workpiece firmly before drilling to prevent movement. Use appropriate cutting fluid or coolant when drilling hard metals to extend bit life and improve cut quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
