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.
