Abstract: The invention is based on a method for producing a screw connection by means of a cutout screwdriver (10) that terminates a screw driving operation when a predetermined torque is achieved. According to the invention, data relating to an operation are detected in the cutout screwdriver (10) and transmitted to an external monitoring unit (20). The invention also discloses a device for executing the method as well as a cutout screwdriver.

Abstract: A guard for a power tool with a rotatably driven insertion tool (14) is configured to cover at least portions of the insertion tool (14). At least one blocking means (32, 40) prevents the insertion tool (14) from turning around an axis of rotation (18).

Abstract: An electric hand tool having a machine housing, with an electric motor accommodated in the machine housing for driving a tool, and a fan wheel accommodated in the machine housing for generating a main cooling air current that flows from a main air inlet to a main air outlet through the machine housing, which said fan wheel creates a suction space and a pressure space on opposite sides when it rotates, wherein means for generating an additional air current are provided and configured such that the additional air current flows onto at least one machine component that is located outside of or in a low-flow region of the main cooling air current, wherein the electric motor includes a motor winding with winding heads that project outward on at least one end face of the electric motor, the fan wheel is located with axial clearance in front of the end face of the electric motor and is configured such that the suction space is located in front of the end face of the electric motor where the winding heads are located,

Abstract: The present invention is based on a method for operating a disengagable screwdriver (10) having a drive motor (12) and a shut-off device (20), with which a driving of a screw tool (16) is halted when a specified cutoff torque is reached. It is proposed that the drive motor (12) is switched off before the specified cutoff torque is reached. A disengagable screwdriver (10) is also proposed.

Abstract: A guard device for a hand power tool, in the form of a sanding/grinding hand power tool, has a wheel guard enclosing at least part of a rotating tool in a radial direction; a guide for guiding the wheel guard along a work piece, and comprising a fastening device for mounting the wheel guard on the hand power tool, wherein the guide is joined with the wheel guard in torsion-resistant fashion, and the wheel guard is mounted in a fashion that allows it to move relative to the fastening device; and a depth-of-cut stop limiting the relative movement of the wheel guard and fastening device, and being lockable in position with positive engagement in preselected stepped positions.

Abstract: The invention is based on a guard device (33) for a power tool, in particular for a sanding power tool, having a protective cover (40) that is provided to at least partially encompass a disk-shaped, rotating tool, and having a dust removal tube (52), the longitudinal axis of which is located at an angle of up to 80° to the axis of rotation of the tool. It is proposed that part of the dust removal tube (52) passes through the plane of a flat side of the tool.

Abstract: An electric hand tool is described that includes a machine housing (1) with an electric motor (12) accommodated in the machine housing (11) for driving a tool (13), and a fan wheel (21) accommodated in the machine housing (11) for generating a cooling air current that flows through the machine housing (11), which said fan wheel creates a suction space (22) and a pressure space (23) on opposite sides when it rotates. To increase the performance of the electric hand tool with longer idle periods for the machine components, purposeful cooling is carried out by providing means for generating an additional air current, which said means are configured such that the additional air current flows to machine components that are located outside of or in a low-flow region of the cooling air current.

Abstract: A cutoff disc, having an outer periphery provided with particles which are released during wear, a central opening for passage and clamping on a work spindle for the rotary driving on a grinding hand power tool, and an outer ring region which is provided on an outer edge, the outer ring region extending radially outwardly with a tip and forming a small cutting edge.

Abstract: The invention is based on a guard device (33) for a hand power tool, in particular for a sanding/grinding hand power tool, comprising a wheel guard (40) that is provided to enclose at least part of a rotating tool in the radial direction, and comprising a guide means for guiding the wheel guard (40) along a work piece (30), as well as a fastening device for fastening the wheel guard (40) to the hand power tool.
