Product Description

The EAGLE CUTTING TOOL C300-016-D is a 1/4-inch cobalt jobber-length twist drill bit manufactured in the USA. Cobalt high-speed steel construction provides superior heat resistance and edge retention compared to standard HSS bits, making this drill well suited for cutting through harder materials including stainless steel, cast iron, hard alloys, and other tough metals. At 0.5 pounds, the bit is sized for standard drill chucks and compatible with bench drill presses, hand drills, and magnetic drills. Electricians, plumbers, pipefitters, HVAC technicians, and general trade mechanics rely on jobber-length drills for everyday hole-making tasks in metal fabrication and on-site service work.

This 1/4-inch cobalt jobber drill is intended for professional trade use where cutting performance and bit longevity under heat and load are priorities. Jobber-length geometry offers a balanced combination of rigidity and reach, making it a practical choice for drilling through sheet metal, structural steel, pipe, and mechanical components encountered in HVAC, plumbing, electrical, and industrial maintenance applications. The USA-made designation indicates domestic manufacture, which meets procurement requirements on certain commercial and public-works job sites.
