Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener includes an abrasive medium having an abrasive surface. A stationary tool support guide provides a guide surface that supports a side of the tool during presentation of a cutting edge of the tool against the abrasive surface. A rotatable edge guide has a roller member with a curvilinearly extending outer surface. The roller member is rotatable about an edge guide roller axis and is moveable between a deployed position and a retracted position. In the deployed position, the roller member is positioned to engage, via rolling contact, the cutting edge during the presentation of the cutting edge against the abrasive surface. In the retracted position, the roller member is positioned to provide a non-contacting clearing relation with the cutting edge during said presentation.

An attachment for a drill comprises a shank with a chuck configured to mount the attachment to the drill. A housing on the shank comprises a threaded end and a hollow chamber. A compression bladder having a tubular opening through it is configured to be inserted into the hollow chamber. A tube comprising a sanding or cleaning surface located on the inner surface of the tube is configured to be insertable into the tubular opening of the compression bladder. A threaded lid having a circular opening that is at least the same diameter as the inner diameter of the tube is configured to mount onto the housing at the threaded end and compress the compression bladder thereby reducing the diameter of the tubular opening and compressing the compression bladder against the tube to secure the tube within the housing.

A tool hanging system. The tool hanging system includes a power tool having a mount receiving portion. A mounting attachment is engaged with the mount receiving portion. The mounting attachment includes a first portion adjacent to the power tool and an overhang portion spaced apart from and opposite the first portion. A groove is located between the first portion and the overhang portion. The mounting attachment also includes a peg board projection, the peg board projection projecting away from the power tool and past the overhang portion. The peg board projection engages with a pegboard.

The invention relates to apparatus for polishing a running base that comprises a blade with two opposing blade edges separated one from the other by an intermediate section; the polishing apparatus comprising: a support body, and blade alignment guide means; wherein the support body is capable of carrying a polishing surface which comprises: a profile which is adapted to conform with one or more portions of the intermediate section; and wherein the blade alignment guide means comprise one or more pairs of first and second blade alignment guides, which first and second blade alignment guides in each pair are separated from each other by the polishing surface, and further wherein the blade alignment guide means is adapted to receive and/or guide and/or constrain a running base so that when the intermediate section between the two edges of the running base is brought into contact with the polishing surface, there is no contact between the polishing surface and any part of the two opposing blade edges of the running base.

A protection device for a power tool is provided. The power tool can be, in particular, a hand-held battery-operated power tool, such as a cut-off grinder. The power tool preferably has main components in a main region, such as a motor, transmission and rechargeable batteries, which are protected effectively from mechanical damage, e.g. when dropped, by the protection device. Moreover, the protection device prevents the transmission of vibrations in the power tool to the user. In a second aspect, the invention relates to a system which comprises a protection device and a power tool.

The disclosed solution comprises a device for changing abrading products (30), the device (1) comprising a detacher (2) comprising a table (10), a blade (14) adapted to penetrate into between an abrading product (30) and the gripping means (34) of the abrading tool (4), and means (16, 18, 19) to co-planarly adjust the mutual distance (d) between the table (10) and the blade (14) to correspond to the thickness (t) of the abrading product (30) in the absence of the abrading product (30).

A hand-held grinding machine includes at least one grinding device for receiving or forming a grinding means, a drive device for driving the grinding device, at least one actuating element for controlling the drive device, and a drive housing, which receives the drive device and has a longitudinal-axis portion arranged about a longitudinal axis at least substantially perpendicular to an axis of rotation of the drive device. The drive housing further includes a front portion, which surrounds a region of an intersection point of the axis of rotation and the longitudinal axis. The front portion includes a dome-shaped grip surface, within which the actuating element is arranged on a side, facing away from the longitudinal-axis portion, of a plane which is perpendicular to the longitudinal axis and includes the axis of rotation.

A portable electric tool includes an output shaft extending in an axial direction and configured to be rotatable, a tool accessory configured to perform an eccentric circular motion according to the rotation of the output shaft, a dust collection fan fixed to the output shaft so as to circumferentially surround the output shaft, a motor disposed on an opposite side of the dust collection fan from the tool accessory in the axial direction and configured to provide a rotational driving force to the output shaft, a motor cooling fan disposed between the dust collection fan and the motor in the axial direction, a first weight attached to one of the dust collection fan and the motor cooling fan and having a specific gravity higher than the one of the fans, and a second weight disposed at a position different from the first weight in the axial direction.

The present invention relates to a floor surfacing machine (1) comprising a frame (2) that is carried by a first wheel (3) and a second wheel (4). The floor surfacing machine (1) further comprises a first motor (6), a handle arrangement (7), at least one planetary head (15) that is rotatably mounted to the frame (2) and at least one satellite surfacing head (19, 20, 21) that is rotatably mounted to the planetary head (15), where the first motor (6) is arranged to propel the planetary head (15). The floor surfacing machine (1) comprises a first control unit (10), and a remote control panel (11) which in turn comprises a second control unit (12) that is arranged to communicate with the first control unit (10). The floor surfacing machine (1) also comprises a second motor (22) that is arranged to propel the satellite surfacing heads (19, 20, 21) such that the planetary head (15) and the satellite surfacing heads (19, 20, 21) are independently operable.

A handheld machine tool comprises a machine tool main body and a tool part. The machine tool main body comprises a round housing, a grip portion and a convex portion. The round housing is a cylindrical shape and has a shaft accommodation portion disposed at the bottom. The tool part is connected to the machine tool main body through the shaft accommodation portion. The grip portion and the convex portion are disposed on a side of the round housing. The handheld machine tool further comprises a first button and a second button. The first button is located in an inertial direction of rotation of the machine tool main body during operation. When a user keeps pressing the first button with the finger to drive the tool part to operate continuously, the machine tool main body pushes the first button to the finger pressed thereon along the inertia direction.
