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 cordless drill
