Abstract (en)

[origin: EP2517835A2] The tool has a tangential hammer mechanism (10) including an anvil (60) associated to an output shaft (30), and a hammer (70) associated to a drive shaft (50). The hammer is axially moved under force application of a spring (80) and a sliding block guide (90). The hammer is strikable against the anvil under rotation of the hammer around the drive shaft. The guide includes a thread-like control contour (91), which includes slopes in an anvil closer section (93) and anvil far section (94), respectively. The slopes are different from each other.
