To permit torque setting and torque coupling fixed without application of a high separative force to a transmitting member or a clutch part.

This hand hold type machine tool has a spindle 12 and a clutch 13 arranged in the driving path between a motor and the spindle 12 and equipped with an adjusting member 23 for adjustment of different operating styles. At least in one adjusting position which the member 23 takes, the parts 15 and 18 of the clutch 13 are connected so that it 13 remains stationary owing to the coupling based on the connection in terms of shape in the rotating direction, and at this time, no excessive axial force should act on the pats 15 and 18 of the clutch.
