Description

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.
