Make fast bit changes—all of these bits have the same shank diameter, eliminating the need for different collets to hold each size.

Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

Carbide is harder, stronger, and more wear resistant than cobalt steel and high-speed steel for better performance on hard and abrasive materials.
