A handheld electric tightening tool includes a housing and a sealing arrangement. The sealing arrangement is adapted to seal a first portion of the housing from a second portion of the housing and includes a sealing element and a spring. The sealing element includes a first portion adapted to bear against a shoulder formed in the housing, and a second portion adapted to bear against a portion of an outer surface of a rotating axle of the tool. The spring is adapted to at a first end bear against a shoulder formed in the sealing element and at a second end bear against a supporting element arranged on the axle, such that a force is exerted on the sealing element urging the sealing element against the shoulder formed in the housing.

An attachment part for a power tool includes an elongated housing including an upper housing part, a lower housing part and an interconnection structure that interconnects the upper and lower housing parts. An input gear for connection to an output shaft of a power tool is arranged at a first end of the housing. An output gear with an output interface is arranged at a second end of the housing. The interconnecting structure includes a sleeve member extending through a first central bore at the first end of the upper housing part, which sleeve member receives the input gear, and a fixation member extending through a second central bore at the first end of the lower housing part and which is arranged to be secured to the sleeve member to clamp the upper and lower housing parts. A tool assembly includes a power tool and the attachment part.

A hand-held power tool has a tool holder for holding a tool, an electric motor for driving the tool holder, and a handle for holding and guiding the hand-held power tool. A button has a button housing, a pin that can be moved on an actuation axis, and an electric slider which is connected to the pin and which slides on an electric slider track. The button housing is suspended in the handle in such a way that the button housing can be pivoted about a pivot axis perpendicular to the actuation axis.

A tool holder device includes a receptacle having two conduits perpendicular to each other, a spindle and a shaft are rotatably engaged in the conduits of the receptacle and have bevel gears meshed with each other for allowing the shaft to be rotated relative to the receptacle by the spindle, a housing is secured to the receptacle, a flexible shank is secured to the spindle, a stem is secured to the flexible shank, a flexible sheath is engaged onto the flexible shank and is secured to the receptacle, and a control ferrule is secured to the flexible sheath, and the stem is rotatably received and engaged in the control ferrule. The flexible shank and the flexible sheath allow the tool holder device to be easily operated by the user in a tiny working space.

The present invention relates to a driver system and method for engaging an article. During operational use of the driver system the user starts with the alignment of a bit and a cavity of the article, the bit is rotated to move a wedge into an internal wedge slot within the cavity of the article. This engagement of the wedge and the internal wedge slot locks the lateral movement of the bit relative to the article, therein allowing for the bit to stay engaged within the article during rotational or torsional force induced upon the article by the user of the bit.

A powered socket wrench assembly includes a power tool that has a back end and a front end. The power tool is elongated along a longitudinal axis extending between the back end and the front end thereby facilitating the power tool to be inserted into a hard to reach area. Additionally, the power tool includes a chuck that is rotated in a first direction or a second direction when the power tool is turned on. A drive unit is insertable into the chuck on the power tool thereby facilitating the power tool to rotate the drive unit when the power tool is turned on. The drive unit includes a socket that is rotatable about an axis oriented perpendicular to the longitudinal axis of the power tool when the power tool is turned on.

An accessory for use with a rotary power tool having a rotatable spindle and a first mating member. The accessory includes a housing having a body and a plurality of arms extending therefrom, a hub rotatably supported within the housing between the arms and configured to be coupled to the spindle to receive torque therefrom, a ball detent disposed within the hub and selectively engagable with the spindle to axially lock the accessory to the power tool, a sleeve axially slidable along the arms and relative to the hub between a first position in which the sleeve biases the ball detent radially inward and into engagement with the spindle when coupled to the hub to axially secure the accessory to the tool, and a second position in which the ball detent is disengageable from the spindle to release the accessory from the tool, and a second mating member axially fixed to the arms of the housing, wherein the sleeve is slidable between the second mating member and the body of the housing, and wherein the first and second mating members are engaged when the accessory is axially secured to the tool to rotationally fix the accessory to the tool.

A filing and fastener driving bit assembly for deburring the end of a pipe includes a shaft that has a first end and a second end. A first section of the shaft that is positioned adjacent to the first end is hexagonally shaped. The first section is insertable into a chuck of a rotary tool to couple the shaft to the rotary tool. A second section of the shaft that is positioned between the first section and a second end of the shaft is textured. The second section is used to file an edge of a tubular substrate, such as Electrical Metallic Tubing, as the shaft is rotated by the rotary tool. A screwdriver tip that is coupled to the second end of the shaft is insertable into a complementary head of a fastener, positioning a user to utilize the rotary tool to drive the fastener.

A portable device is disclosed for drilling a hole through a plate and into a wooden tie and/or inserting a lag screw into the hole in the plate and into the wooden tie. The portable device may include a handle and a removable drill with a rechargeable battery that provides power to the portable device. In various embodiments, the portable device may include a gear ratio and gear reduction system configured to allow a user to change speed and torque settings for the portable device independent from the battery-powered drill. In some embodiments, the portable device may include a quick connect/disconnect component configured to enable the portable device to be used as a tie drill device or a lag screw inserter device by interchangeably connecting either a drill bit or a lag screw socket to the portable device.
