Definitions

  • the absorber mass is formed substantially cylindrical. This allows a symmetrical and in the circumferential direction evenly distributed mass distribution around the drill sleeve to be achieved, which proves to be useful in terms of vibration damping.
  • the axial extension of the absorber mass may advantageously also be 5 to 20 mm. It is advantageously 3 to 8 times their wall thickness.
