Abstract

The outer tube (2) can be activated by a striker part (8) displaceable longitudinally and arranged over the inner tube (3). The insert end (5) extending on both sides over the rotary mechanism has on the rotary striking mechanism side a compensation ring (10) which has a hardness below that of the tube material and the striker part. The compensation ring has a curved surface on both sides, corresponding to the abutting end piece (11) of the insert end. In the housing (9) on the curved surface of the compensation ring lubricating holes (12) are provided.
