The invention is based on a system with a tool-holding fixture, which fixture has a slaving device () by way of which an inserted tool () can be connected operatively to a drive shaft (), and with an inserted tool () which can be connected operatively to the slaving device () via at least one detent element () that is supported movably counter to a spring element (), which detent element snaps into place in an operating position of the inserted tool () and fixes the inserted tool () by positive engagement. It is proposed that the tool-holding fixture and the inserted tool () have at least two corresponding shaped elements (), adapted to one another, to facilitate installation of the inserted tool ().

System with a tool-holding fixture

A power tool, in particular a right-angle grinder, includes a motor and a gear, the motor and/or the gear embodied as a mountable function module. The gear is embodied as a mountable function module, with a gear input shaft supported in a gearbox, and the gear input shaft is fixed in the gearbox via at least one detent connection.

Power tool, in particular angle grinder

A portable power tool includes a motor housing () and a housing cover () that is attached to the motor housing (). The portable power tool includes insulation () adjacent to the motor housing () and the housing cover (), which are guided through a guide () in the direction toward the motor housing () and/or the housing cover ().

Hand-held power tool

The invention relates to a hand power tool (), having a housing (), an electric motor accommodated in the housing (), and a battery pack (), releasably locked to the housing (), for supplying the electric motor with electric current. At least one spring/damping element (), mounted between the battery pack () and the housing () of the hand power tool (), is provided, for damping vibration and -or eliminating a locking-dictated play between the battery pack () and the housing ().

Electrical hand power tool with battery pack

The invention is based on an insertable tool with a rotationally driven disk-shaped hub (), to which a grinding means () is secured in the radially outer region. It is proposed that the hub () is embodied with a flexural strength that varies in the radial direction.

Utility tool with rotatingly driveable, disk-shaped hub

A system with a tool-holding socket, which has a driver device that can be used to operationally connect an insert tool to a drive shaft, and has an insert tool, wherein the insert tool can be operationally connected to the driver device by at least one detent element which is supported so that can move in opposition to a spring element, engages in detent fashion in an operating position of the insert tool, and fixes the insert tool in a positively engaging fashion, wherein at least part of a mechanism for preventing a laterally inverted installation of the insert tool is formed at least onto the tool-holding socket.

In a hand-guided electrical toolwith a housingthat has a receiving collarembodied on it and with a guard hoodthat can be attached to the receiving collarand has a clamping strap, which can move freely around the receiving collarin a first position and rests snugly against the receiving collarin a second position, a secure connection between the guard hoodand the housingis achieved by virtue of the fact that the receiving collarhas at least one protrusion, which protrudes beyond the second area in the radial direction away from the spindle axle, and between the protrusionand the housing, there is a distance h, which approximately corresponds to the width b of the clamping strap, and by virtue of the fact that that the clamping straphas at least one indentationso that the first diameter dof the openingof the clamping strapin the vicinity of the indentationis greater than the second diameter din the remaining region, wherein the first diameter dis of such a size that the clamping strapcan be moved over the protrusionand the second diameter dis of such a size that the clamping strapcannot be moved over the protrusion

Hand-guided electric tool comprising a guard

The invention is based on an insert tool with a rotationally driveable disk-shaped hub and an abrasive disposed in particular in a radially outer region, in particular of the kind used for a cut-off wheel, a grinding disk, a rough grinding disk, a cutting disk, or an abrasive paper. The invention proposes that the hub () have at least one mount (), which is disposed off-center, extends in the axial direction (), and is intended for a bolt that constitutes a functional element of a quick-action clamping system.

Attachment and rapid-chucking system, comprising a rotatably driven, disc-shaped hub

A battery-operated electrical tool () is provided with a machine housing () that has a longish, substantially rod-shaped housing portion () containing an electric drive motor () and an end portion () on which a terminal connection surface () with push-in receptacle () for the detachable attachment of a battery packet () is provided, which said battery packet is provided with a connection part () that comprises a seating surface () matched to the connection surface () for seating on said connection surface, and comprising a push-in part () engaging in the push-in receptacle (). The end portion () is inflected toward one side in relation to the housing portion () out of the direction of longitudinal extension. The terminal connection surface () of the end portion () extends within a plane () that is oriented skew in relation to a plane () extending substantially perpendicularly to the longitudinal axis () of the housing portion ().

Battery operated electrical tool

The invention is based on an insertable tool having a rotationally drivable, disk-shaped hub (), on which a grinding means () forming a cutoff disk, grinding disk, roughing disk, or abrasive disk is secured in the radially outer region. It is proposed that the grinding means () and the hub () are joined via joining means () in the manner of a positive connection at least in the direction of rotation.

Heavy-duty tool with a rotationally driven, disk-shaped hub

The invention is based on a tool receiver for a grinder, in particular for a handheld angle grinder (), having a carrier device (), via which an application tool () can be actively connected to a drive shaft (). It is proposed that the application tool () be actively connectable to the carrier device () via at least one detent element () movable against a spring force that snaps into place in an operating position of the application tool () and immobilizes the application tool () with positive engagement.

Receptacle for grinder tools

The invention is based on a hand power tool, in particular a manually operated right angle grinding machine or a manual circular saw, with a driver mechanism (), which can operatively connect an inserted tool () to a drive shaft (). The invention proposes that at least one sensor () can detect at least one procedural step in the changing of an inserted tool () and can produce a signal.

Hand tool comprising a sensor for emitting a signal when the tool attachment is replaced

An insert tool with grinding blade and a supporting disk, and with a hub, which has at least one opening that permits the hub to be clamped to a driver flange of a grinder, which flange is connected to a drive shaft, wherein the hub is constituted by a component that is separate from the supporting disk, the hub can be operatively connected to a driver device of the grinder by means of at least one detent element, which is supported so that it can move in opposition to a spring element and which engages in detent fashion in an operating position of the hub and fixes the hub in a positively engaging manner.

Attachment for grinder

Grinder

A grinding machine tool receptacle for a hand-guided angle grinding machine has a slaving device by which an insert tool is operatively connectable to a drive shaft, the insert tool is operatively connectable to the slaving device via at least one detent element supported movably counter to a spring element, which detent element snaps into place in an operating position of the insert tool driven by the spring element and fixes the insert tool by positive engagement, the detent element is displaceable in the axial direction counter to the spring element, and the insert tool is connected to the slaving device in the circumferential direction via at least a first element and in the axial direction via at least a second element, with the second element arranged for fixing of the insert tool with a spring force.
