ABSTRACT:
A drilling and chipping tool includes a striker mechanism and a holder (10) for a tool bit. Blows are transmitted to the holder and the tool bit through an axially extending anvil (4) located in the tool. The anvil (4) can be connected to a shifting member (7) by a locking element (6). The shifting element (7) is axially displaceable by an actuation member (8). The axial displacement of the shifting member (7) moves the anvil (4) between a first position for transmitting blows and a second position for blocking the transmission of blows from the anvil (4) to the holder (10).
