A hand held power tool has a coupling formed for transmission of torques of different values and including at least two coupling parts provided with transmission members for rotary-fixed connection with one another, a coupling spring having an adjustable tensioning force operatable for holding one of the coupling members of one of the coupling parts in a rotary-locked engagement with another of the coupling members of another of the coupling parts, and blocking members with which the coupling parts are rotary-fixed coupled in addition to the transmission members, and which are bringable in engagement with one another in a drilling operation or an impact drilling operation for transmitting a maximum torque. |
