An edge-removing tool for sheet metal includes a head with a rotating cutting tool. The head has at least one guide for an edge. The head preferably includes a sleeve with the guide. The tool can be used to separate edges of an angled and/or welded sheet metal connection.

A handle adjustment assembly is attached to a walk-behind lawn mower, wherein the handle adjustment assembly is rotatably adjustable relative to a deck of the mower to allow the handle to be adjusted to multiple different heights relative to the ground at distinct operative positions. The handle adjustment assembly is also rotatable to allow the handle to be adjusted to a stored position adjacent to the deck, wherein the mower can be stored in a substantially vertical orientation.

This invention is a device and method for weighting and balancing ar hand-held electric angle grinder. A weight shaft is mounted on the frame of the angle grinder coaxially with the axis of rotation of the angle grinder motor. A selection of weights can be mounted on the weight shaft to provide extra downward pressure, through the motor and frame, to the grinding disc of the angle grinder. The weights are also selected to suppress vibration that is produced by the interaction between the grinding disc and the surface. As a result, the present invention provides an angle grinder that is easier and less exhaustingI to use, is less likely to have any harmful effects on the user, is able to provide a more effective functioning of the angle grinder, and is able to provide a treated work surface of better quality and less expense.

A portable grinding tool includes a casing structure and a drive unit. The casing structure includes a main body part defining a first axis, and a grip part extending from the main body part along a second axis. The drive unit is mounted to the main body part and includes a rotating shaft for outputting rotational kinetic energy, the rotating shaft has an output section that extends along the first axis and passes out through the main body part. The output section and the grip part cooperate to define an angle included therebetween and ranging between 95 and 135 degrees.

A hand-guided treatment device is configured for use in working positions tilted relative to each other by a tilt angle of at least 45° about a device longitudinal axis. The device has a device housing, a handle operating unit with a handle extending with a main direction component parallel to the device longitudinal axis and a finger-operable operating element within finger reach of the handle, and a display field arranged on an outside of the device housing with at least one optical display element. The display field is arranged offset relative to the operating element in a housing circumferential direction about the device longitudinal axis and extends in the housing circumferential direction over a housing edge and/or with a curved or kinked course.

Methods and apparatus for a vibration dampening system having an adaptor with a user contact surface and a power tool contact surface. The adaptor can include a core to reduce vibration transfer from the tool to the hands of a user. In embodiments, the core comprises a viscoelastic material that lightens a base elastomer to form liquid-filled closed cells structures.

A tool for removing a coating from an interior surface of a component. The tool includes a rotary device; a grinding attachment attached to the rotary device; a tool holder configured to: set an axial position of the grinding attachment coupled to the rotary device over the coating on the interior surface of the component; and set a radial position of the grinding attachment coupled to the rotary device, the radial position defining a cutting depth of the grinding attachment into the coating on the interior surface of the component; and a wheel assembly coupled to the tool holder for guiding the tool holder about an interior perimeter of the component.

A hand-held power tool includes a housing, a filter support, a plurality of securing element, and an actuating unit. The filter support has receiving openings, at least one first fixing element, and at least one second fixing element. The receiving openings are configured to receive filter elements configured to seal the hand-held power tool against a penetration of dust into the housing of the hand-held power tool. First and second fixing elements are fixable to corresponding securing elements arranged on the hand-held power tool, and are configured to releasably fix the filter support to the housing. The actuation unit is actuatable to release the filter support from the hand-held power tool.

A power tool includes a handle detector that is less susceptible to vibrations and is highly durable and reliable. A grinder includes a brushless motor, an inner housing accommodating the brushless motor, a rubber cylinder, a spindle driven by the brushless motor, and an outer housing enclosing the inner housing and holding the inner housing with the rubber cylinder in between. The outer housing includes a handle mount and at least one handle detector that detects a side handle attached.

An adapter assembly is provided for converting a first oscillating motion from an oscillating tool to a second oscillating motion at a wheel that is useful for applying polymers and other films to doors, windows, and other surfaces or for applying rubber gaskets around a window during installation of the window. The adapter assembly is provided with an adapter that tapers in the anterior direction when attached to an oscillating tool. An axle is provided at the distal end of the adapter and attaches to a concentrically aligned bearing within the wheel.
