Application

For producing 60° counterbores up to 1300 N/mm².

Execution

  • Profile-ground triple-edge countersink with radial relief, with extremely uneven pitch

Advantage

  • Radial relief ensures optimum chip breaking
  • Uneven pitch ensures excellent surfaces without chatter marks and minimisation of cutting forces
  • 3-sided shaft ensures very good power transmission and prevents the tool from spinning in the drill chuck or even in the cordless drill
