Cobalt Drill Bits

Cobalt Drill Bits for Drilling Hard Metals and Tough Materials

Cobalt drill bits are designed for drilling through hard metals such as stainless steel, cast iron, and other tough alloys. High-speed steel bits with cobalt content provide improved heat resistance and durability during demanding drilling tasks. These bits are often used alongside carbide drill bits when working with extremely hard materials in fabrication and metalworking applications.

For finishing drilled holes and creating clean edges for fasteners, technicians frequently rely on countersinks to form smooth recesses. In repair and maintenance work, double-end drill bits provide extended usability by offering two cutting ends in a single bit.
