    Abstract: The invention relates to a device for releasably connecting two coaxially aligned tool parts (1, 2) which can be axially pressed against each other on separating surfaces (36, 38) that face each other with a clamping device. According to the invention, at least one of the separating surfaces (38) is divided into several axially rigid and torsionally soft bearing segments (50) which are spaced in a peripheral direction, in order to dampen the torsional oscillations that occur during the work process and reduce noise.

    Abstract: A hand machine tool includes a tool retainer that retains a tool, a motor that drives the tool retainer in a rotary motion, and a torque-controlled sliding clutch that is connected in a drivetrain between the motor and the tool retainer. The sliding clutch includes a first clutch disk, a second clutch disk, a spring and a controlling unit which can be activated manually. The second clutch disk is arranged displaceably alongside an axis limited by a stop in the direction toward the first clutch disk. Force is applied to the second clutch disk by the spring alongside the axis in the direction toward the first clutch disk. The manually activated controlling unit variably sets an axial distance between the first clutch disk and the stop, with which an engagement depth of the first clutch disk with the second clutch disk can be defined.

    Abstract: A method for controlling a motor (2) which drives a disk-shaped tool (4) of a power tool (1) and to which a motor voltage in the amount of a nominal value is applied in an “on” position of a motor switch (6), includes determination of an actual motor current (IM) applied to the motor (2) and comparing it to a first predetermined threshold (GW1), and automatically triggering of a control process for protecting the motor (2) when an overload condition which is defined in that the first predetermined threshold (GW1) is exceeded beyond a first predetermined limiting time period (grDt1), is met, the control process including reduction of the motor voltage applied to the motor (2) by a magnitude that can be perceived by the user as a choke value.

    Abstract: A cutting insert shapes metallic workpieces by chipping. The cutting insert is especially suited for use in solid drills or double-bit cutters. It has at least one cutting edge which is delimited by a chipping face and a flank extends between two cutting corners. The cutting edge includes two sections which form an obtuse angle and in the area of a roof-shaped tip merge into each other. The chipping face has a raised shaped chipping element which extends from the inside of the chipping face as far as the cutting edge, from where it reaches beyond the roof-shaped tip partially across the two sections of the cutting edge. The cutting edge sections and the adjoining chipping faces include a step delimiting the shaped chipping element, the edges of which step serve as additional cutting edges of the shaped chipping element.
