Abstract: A pneumatic hammer extender arm assembly is provided comprising an elongated extender arm body defining a hammer engaging portion formed at a first end of the body, and a hammerhead engaging portion formed at a second end of the body. A hammerhead is detachably engageable to the hammerhead engaging portion to allow for quick change of the hammerhead without the need for any tools. The hammerhead may alternately be implemented to engage and apply an impact force to a fastener that may be axially offset from the extender arm body.

Abstract: An air hammer tool having a head section defining a blind-hole and a contact surface surrounding the blind-hole, configured to be coupled with an air hammer to provide a percussive force through the contact face of the tool to an axle flange around an axle shaft flange hole, after a flange nut has been removed, to shock a cone-washer disposed therein. The design and solution to this long-felt issue allows for easier removal of the cone-washers from the axle shaft flange holes while not contacting the respective studs and lowering chances for damage of the axle componentry.

Abstract: A drill bit includes a tool body having a main body in the form of a cylinder. A chip removing structure is provided on the main body. The tool body has a distal end provided with a clamping slot and a cutter inlaid in the clamping slot. The cutter has at least two blade portions arranged circumferentially on the distal end of the tool body and extending radially relative to the tool body. Each of the blade portions has a front side along the drill bit's rotating direction and a back side against the rotating direction. The clamping slot covers the back side of one blade portion by an area larger than that used to cover the front side of the same blade portion.

Abstract: A hand tool impacting device may include a drive shaft, an impaler disk, and a floating pin positioned in an aperture of the drive shaft. Circular ramps along an outer edge of the impaler disk may interact with a stationary pin to translate the drive shaft and generate an impacting motion. A pair of springs placed against a side of the floating pin may allow a tool bit to engage or disengage the impaler disk, for selective use of translational impacting motion or rotational torque. An impact bit for engaging the impaler disk may include a tool head that may engage a work piece and a tool shaft inserted into the drive shaft to engage the floating pin.

Abstract: A point chisel includes a substantially cylindrical shank and a working end region that tapers to a point. The working end region has at least three converging substantially planar surfaces, each with a protruding elongate rib extending along at least part of its length. Adjacent surfaces meet along at least part of their length at substantially straight edges between adjacent ribs. A flat chisel includes a substantially cylindrical shank and a working end region with a pair of converging substantially planar surfaces that include a plurality of protruding elongate ribs extending along at least part of its length. Each rib has, along the majority of its length, a substantially constant height above the surface from which it protrudes. Each chisel is made from steel, with the shank having a bainitic microstructure and the working end region having a martensitic microstructure.

Abstract: A fastener driver, fastener driver assembly and method for operating a fastener driver. The fastener driver includes a shoulder linking a neck to a head, where the shoulder includes a cross-sectional shoulder shape having small and large cross-sectional sections that can be inserted into an opening in a nose piece. The user can then rotate the fastener driver and the larger cross-sectional portions of the shoulder can block the fastener driver assembly from advancing out of the opening. The fastener driver assembly increases the speed of operation by including a plurality of pins on a head of the fastener driver to allow the simultaneous fastening of a plurality of fasteners, and by being adapted to conveniently insert into a conventional power tool such as an air hammer.
