Abstract

A drill comprising: a housing (2, 4); a motor (100) mounted in the housing (2, 4) having a drive spindle (16); an output spindle (60) capable of being rotationally driven by the drive spindle (16) via a torque clutch, the output spindle (60) having an impact surface (136) and a central axis (102); a tangential impact mechanism for superimposing tangential impacts onto the output spindle (60) when activated, the tangential impact mechanism comprising; a sleeve (74) rotatably mounted on the output spindle (60) which is capable of being rotationally driven by the drive spindle (16); and an anvil (116) rotatably mounted onto the output spindle (60) and which is connected to the sleeve (74) so that relative rotation of the sleeve (74) and spindle (60) results in the anvil (74) repetitively striking the at least one impact surface (136); wherein the output spindle (60) and the sleeve (74) are rotationally driven by the drive spindle (16) via a gear system (70, 78, 94); characterised in the drive spindle (16) drives the sleeve (74) via the gear system at a first rotational rate when the torque clutch is not slipping and at a second rotational rate when the torque clutch is slipping.
