Features

High heat resistance from cobalt alloy supports drilling in hard ferrous metals such as stainless steel and alloy steels.

Improved wear resistance relative to standard high-speed steel bits, extending bit life under repeated drilling in tough materials.

Jobber-length profile provides versatile reach for through-holes, pocketing, and awkward angles in metalworking tasks.

Designed to maintain cutting edge integrity during high-temperature drilling, reducing the need for frequent bit changes in busy shop environments.

Package includes 12 pieces of #11 cobalt jobber length drill bits

Part of the D/ACO Series, intended for use in metalworking applications requiring durable, heat-resistant cutting edges

Ideal for workshops handling stainless steel, alloy steels, and cast iron where longer bit life and consistent performance are valuable
