Specs

    Quantity: 1 pc

    Cutting diameter: 21.50 mm

    Shank diameter: 1/2″ (12.7 mm)

    Shank type: Reduced shank

    Material: Cobalt drill bit (high-hardness alloy)

Features

    Cobalt alloy construction provides superior wear resistance and elevated heat tolerance for drilling hard metals.

    Reduced shank design allows a larger cutting diameter within a compact shank geometry, enabling efficient material removal in tight setups.

    One-piece construction delivers rigidity under high torque and reduces runout during metalworking tasks.

    Targets hard materials such as stainless steel, alloy steels, and heat-treated steels, where conventional HSS bits dull quickly.

    Ideal for shop fabrication, maintenance, and projects requiring durable drilling through hard metals.
