Abstract:
An adapter (9) for a motor-driven machine tool with a tool to be rotatably driven has positive-fit counterpart pieces (10) on one face (16) which are adapted to positive-fit elements (3) of the tool shaft (1). Multiple axially protruding mandrels (11) are arranged along the circumference on the opposite face (13).
Abstract:
The invention relates to a motor-driven machine tool having a rotationally drivable tool, comprising a tool shaft, on the face of which a fastening device is provided for receiving and fastening the tool. The fastening device is detachably received on the tool shaft. An auxiliary tool for loosening the fastening device has a pull-off unit for loosening the mounting device, the unit engaging the fastening device on the tool shaft from behind, and a support part on the pull-off unit, the part supporting the pull-off unit in the operating mode using a supporting and loosening force on the machine tool. A further auxiliary tool for disposing the fastening device on the tool shaft has a clamping part, which is to be firmly connected to the machine tool in the operating mode, and a pressing unit for applying pressure on the fastening device, wherein the pressing unit is disposed on the clamping part in an adjustable manner
Abstract:
The invention is based on a handheld power saw, having a coupling means (10) for retaining and driving a saw blade (12), and having a guide assembly (14) for guiding an oscillating motion (16) of the saw blade (12).It is proposed that the guide assembly (14) includes at least one lateral bracing means (18, 18′) for shielding the coupling means (10) from shear forces acting on the saw blade (12).
Abstract:
A router has a motor housing that includes an upper piece, and the upper piece of the motor housing includes at least two shells capable of being joined together, the parting plane of which extends essentially in the direction of a vertical axis of the router.
Abstract:
A planer (10), in particular a hand held planer for machining wood, with a planer housing (12), which includes a planer shaft (20), supported rotatably in at least one direction with an outer contour (23), which in a longitudinal groove (46) has at least one planer blade (21), which is braced on a centrifugal wedge (56) that can be prestressed with a spring (54) or the like can be produced more simply and economically in that the centrifugal wedge (56) is fastened to the planer shaft (20), elastically movably relative to it, in captive fashion solely by the spring (54), in particular being removable without destruction, and substantially without touching the planer shaft (20).
Abstract:
In order to achieve an improved chip and shaving ejection in a portable per, a small portion of the motor cooling air stream is diverted and directed through an air passage into a chip ejection channel. The volume flow of this chip ejection air stream may be controlled by a control slider gate to suit various operating conditions. The chip ejection air stream also serves to cool the drive belt and planing head. The diverted air flow keeps the chips in a sufficiently loose state to assure an effective, clog-free ejection of chips. Furthermore, a deflection flap is used in the chip ejection channel to eject the chips to either side of the tool as desired.

Abstract:
A motor-driven machine tool with a tool that can be rotatably driven comprises a drive shaft and a tool shaft on which the tool is received, the rotational movement of the drive shaft being transmissible onto the tool shaft via a coupling device. The drive shaft is rotatably received in pivot bearings in the housing of the machine tool, the coupling device acting upon the drive shaft in the portion between the two pivot bearings.
Abstract:
A router has a housing, which is displaceably accommodated between a starting position and an end position for adjustment relative to a base plate, and a device for displaying the position of the housing.
Abstract:
A router has a housing, from the underside of which a tool fitting for a milling tool connected with a drive motor extends and the housing is displaceably accommodated on guide columns for adjusting the milling depth, a device for adjusting the milling depth, which includes a depth adjusting element that is displaceable in the direction of a vertical axis of the router using an adjusting element and that interacts with a stop element, and a device for locking the depth adjusting element. The device for locking the depth adjusting element is integrated in the device for adjusting the milling depth.
