Execution

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

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