A hand-held drilling machine/driver (1) with a turret head (7), where it is possible to change between at least two tool holders (6), where the turret head (7) is released to rotate by actuating an operating means (15), whereby axial displacing of the rotatable part (12) of the tool holder is allowed, thereby ensuring separation of the driving line (10) of the machine and release of a rotational lock (20) of the turret head (7). Operation of the turret head (7) of the machine occurs in a secure and comfortable way where the user does not need to change his hold on the machine (1), and where the user does not come into physical contact with the tool holder (6). The machine is provided with an operating means (15) having a first contact face (17) which by displacing or turning of the operating means (15) is brought to contact a corresponding contact face (18) connected with the rotatable part (12) of the tool holder, in order to exert a force on the latter for pressing the rotatable part (12) of the tool holder in axial direction and out of engagement with the drive means (10) of the machine.
A hand-held drilling machine/driver of the type where it is possible to change between at least two tool holders mounted in a so-called turret head for rotatable changing where the turret head is released to rotate relative to the machine body by actuating an operating means on the turret head, where the operating means communicates with means which by actuation allow axial displacing of the rotatable part of the tool holder, thereby ensuring separation of the driving line of the machine and release of a rotational lock of the turret head, wherein the operating means has a first contact face which by displacing or turning of the operating means is brought in contact with a corresponding contact face connected with the rotatable part of the tool holder, in order to exert a force on the latter for pressing the rotatable part of the tool holder in axial direction and out of engagement with the drive means of the machine.
