An adjustable sander having a body and a flexible base. The flexible base includes a first end and a second end spaced apart from one another. The first end and second end are each pivotally attached to the body. The flexible base is configured to move between a concave configuration, a neutral configuration, and a convex configuration relative to the body. The adjustable sander further includes a removable sanding surface affixed to a surface of the flexible base that is distal from the body. The adjustable sander also includes a locking mechanism configured to selectively hold the flexible base in a desired concave, neutral or convex configuration. The locking mechanism is characterized in that it includes an axial having a head and a shaft having a series of shaft notches.

A tool includes a first accessory, a second accessory, a first attachment portion configured to allow the first accessory to be detachably attached thereto, a second attachment portion configured to allow the second accessory to be detachably attached thereto, a first intermediate member configured to be displaced from a first non-attachment position to a first attachment position by the attachment of the first accessory to the first attachment portion, a second intermediate member configured to be displaced from a second non-attachment position to a second attachment position by the attachment of the second accessory to the second attachment portion, and a single sensor configured to detect a specific state in which the first intermediate member is located at the first attachment position and the second intermediate member is located at the second attachment position.

A hand-held power tool includes a housing, a motor, a cooling unit, and a plurality of electronics. The housing includes a first housing part and an air intake opening. The motor is assigned to a drive train of the hand-held power tool. The cooling unit is configured to cool the motor. The plurality of electronics is located in the housing. The first housing part includes at least one air channel that is integral with the first housing part. The air intake opening is configured to conduct a cooling air flow directly to the motor via the at least one air channel.

A cooling device for a hand-held power tool, in particular an angle grinder, includes a first air guide channel configured to guide a first airflow and a first air inlet opening configured to guide the first airflow into a housing of the hand-held power tool. The first airflow is guided such that the first airflow extends/flows from the first air inlet opening to a side of the housing that faces away from the first air inlet opening.

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 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 hand operated power tool comprising a housing with a motor and a working element performing an actuating movement if the tool is actuated. The motor is adapted to actuate a tool shaft in order to make it perform a rotational movement. A carrier element is functionally located between the tool shaft actuated by the motor and the working element for translating the rotational movement of the tool shaft into the actuating movement of the working element. In order to provide for a power tool, which allows perfect working of a workpiece with different types of actuating movements and/or working elements, it is suggested that the working element and the carrier element make part of a functional unit constituting a unit separate of the rest of the tool, wherein the functional unit is detachably fixed to the rest of the tool, in particular to the tool shaft.

An accessory for coupling to an attachment mechanism of an oscillating power tool includes a working end, an opposite rear end, and a fitment portion adjacent the rear end portion. The fitment portion includes a central opening having a central portion and a rearward portion open to the rear end, and configured to receive a post of a tool clamping mechanism. The fitment portion further includes a first plurality of openings in communication with and extending radially outward from the central portion, a second plurality of openings not in communication with and positioned radially outward from the central portion. The central portion, the first plurality of openings, and the second plurality of openings are configured to couple the fitment portion to a plurality of different configurations of attachment mechanisms for oscillating power tools.

In order to provide a tool holder for holding a tool for treating the surface of a workpiece by means of which it is possible to treat workpieces in a low-vibratory and convenient manner, it is proposed that the tool holder comprise a disk-shaped base body which has an attachment section for the attachment of the tool holder to a machine tool and at least one resiliently flexible deformation section.

A device for holding and securing backing nuts for tools, such as disk grinders. The device includes a threaded screw that can be inserted into a threaded connector on the tool. Further, the device includes a threaded receiver that can accept one or more threaded backing nuts. The backing nuts are screwed onto the threaded receiver and thus, attached to the tool such that the backing nuts will not be lost, misplaced or stolen.
