A mobile machine tool for coating and/or abrasive machining of a surface of a workpiece or a room using a working device which is mobile with respect to the surface and which includes a tool receptacle for a work tool driven or drivable by a drive motor for machining the surface and/or a coating device with a coating tool for coating the surface. The working device has a guide device having at least one guide contour, particularly a guide surface, for guiding along the surface, wherein the work tool or the coating tool is mounted for moving with respect to the guide device.

A sliding ring for a grinding device consisting of a grinding element and a hood covering the grinding element and a sliding ring attachable to the side of the hood facing a surface to be machined, the sliding ring having a sliding surface provided for sliding on the surface to be machined, the sliding ring consisting of at least one elastic component and a sliding component, the sliding surface being formed on the sliding component and the elastic component being arranged on the side of the sliding component opposite the sliding surface.

A hand-held power tool includes a gearing housing part and accessory equipment. The gearing housing part has at least one machine-side contact element. The accessory equipment has at least one accessory-equipment-side contact element. The machine-side contact element and the accessory-equipment-side contact element can be releasably connected to each other.

A grinder according to one aspect of the present disclosure includes a motor, a housing for housing the motor, a spindle protruding from the housing and configured to be driven to be rotated by the motor, a wheel cover configured to cover a part of a tip end tool attached to the spindle, a detector configured to detect the wheel cover, and a controller configured to stop or restrict the spindle being driven by the motor in response to non-detection of the wheel cover by the detector.

A handheld, hand-guided cutting-off machine (10), which includes a rotating cutting-off wheel, a supporting housing part (36), an output shaft, which is rotatably supported around an output axis (40), a drive motor, a transmission mechanism (19), which connects the drive motor to the output shaft, a flange and a safety guard (24), which covers the cutting-off wheel over a covering area. The cutting-off wheel is rotatably fixedly mounted on the output shaft with the aid of the flange and surrounded by the safety guard (24), which is pivotable around a pivot axis. The safety guard (24), the supporting housing part (36) and the transmission mechanism (19) have maximum distances from the output axis (40) over an outcut angle (), which are less than or equal to half the flange diameter of the flange.

A guard attachment for a grinding tool has a metal body with an upper surface, a side wall along part of a perimeter of the upper surface, and a connector with which it can be attached to a grinding tool. Additional features include a bottom plate opposite the upper surface and a debris outlet attached at one end to the surface and side wall of the guard, and having a magnet removably attached to the other end. The bottom plate swivels outward from the body of the guard to facilitate changing the wheel or disk of the grinding tool. The magnet has an aperture allowing for the passage of air, but prevents sparks from escaping the guard attachment.

A dust shroud having a shroud body with a vacuum port and a tool connection, the shroud body including a top wall and at least one side wall extending downwardly from about a perimeter of the top wall that defines a dust receiving opening, the shroud body having a top wall opening and the tool connection including a flexible fitting with a flexible fitting base joined to the top wall and extending within the top wall opening, the flexible fitting including a plurality of flexible fingers with a base finger portion and an outer finger portion that extends away from top wall and is selectively with a mounting point of the hand held tool and the flexible fingers allowing selective controlled relative movement between the dust shroud and the hand held tool, the fingers having a finger spacing between adjacent flexible fingers and the outwardly extending flexible fingers having a finger length between the top wall and the distal finger end that is greater than 0.75 inches allowing for selective adjustment and relative movement between the dust shroud and the associated hand held grinder.

A power tool having a disk-shaped tool and a guard plate in order to protect the power tool from flying sparks. The guard plate here has devices for supporting a secure standing position of the power tool, wherein the devices include an elastic material and can be preassembled on tabs of the guard plate. An assembly and a method for rapidly mounting a guard plate and devices for supporting a secure standing position of a power tool on a power tool is also provided.

A suction hood for a power tool, which includes a rotating tool, in particular a grinding or cutting tool, for collecting and removing dust generated during the use of the power tool, a first side wall having a first recess, a second side wall having a second recess, and a suction channel connected to the first and second side walls. The diameter of the first recess is greater than the diameter of a flange of the power tool, so that the first recess is positionable around the flange. The diameter of the second recess is greater than the diameter of a clamping element, which is used to detachably fasten the tool on a spindle of the power tool, so that the clamping element may be accommodated in the second recess. The first and second side walls are positioned at a distance from each other which is shorter than the length of the spindle.

An angle grinder (200), which includes a gear neck (210) for connecting a dust hood (100, 100) equipped with a flange (90), the angle grinder (200) including a sensor unit (20), with the aid of which it is possible to detect which type of dust hood (100, 100) is connected to the angle grinder (200), the angle grinder (200) also including rotational direction control electronics (230), which are connected by signals to the sensor unit (20) in such a way that the rotational direction (GGD, GLD) of a cutting wheel (220) of the angle grinder (200) is predefined as a function of the dust hood type detected by the sensor unit (20).
