A striking cap that may include a distal end configured to strike a foreign object. The striking cap may also include a proximal end opposite the distal end. The proximal end may include a protruding ring, where the protruding ring forms a cavity. The cavity may be configured to enable the striking cap to be attached to a striking implement. The proximal medial edge of the protruding ring may include a beveled surface.

A multifunctional substrate repair tool that has a linear body and a plurality of implements on both ends. A head on one end houses a nail claw and ports for selective attachment of blades on the sides and on the top. The ports connect one or more arced blades, each having a striking surface, for penetrating and breaking apart substrate filler layer. Repeated strikes encompassing the fastener head removes filler layer material. A grip connects the head to a bulbous end having at least one of a peen and a protrusion. These are used to indent substrate features and, together with an optional abrasive surface, also located on bulbous end, to dress the cavity left by the blade and nail claw functions. The bulbous end is used as a strike surface for blade and indenting features alike.

The present invention provides a means to achieve enhanced control of repair forces in the automotive body repair industry. In particular, the present invention provides a modified slide hammer and a method to achieve repair through the controlled application of forces otherwise not attainable with existing embodiments. Additionally, the present invention provides an ease of use and versatility of application and mounting at the site of the work in conjunction with and in line with existing devices used in the repair process. The application of the present invention provides increased reliability in the delivery of intended forces at the site of the work. Further, the inherent isolation of repair forces to the intended site of the work by the use of the present invention reduces the likelihood of secondary damage, material waste, or catastrophic failure thereby also enhancing the safety of the operator and the effectivity of repair. Specifically, the present invention may be implemented in conjunction with existing frame pullers in the automotive body repair industry to affect repair while providing facility to avoid obstructions in the path of applied forces.

A range of power tools each includes motor and transmission housings with an electric motor and a transmission mechanism mounted respectively therein, with the transmission mechanism using the rotary output of the motor to drive a cutting tool. An intermediate housing is sandwiched between the motor and transmission housings. Each of the motor housings is the same in shape, and the length of the electric motors in each of the power tool is different to the length of the electric motors in the other power tools in the range. The transmission housing is positioned differently relative to the motor housing in each power tool to accommodate the difference in length in the electric motor in that power tool, the shape of the intermediate housing in each power tool varying relative to the other intermediate housings to accommodate the difference positions of the transmission housings relative to the motor housings.

A compression strength attachment block has a tension strength attachment loop pivotally attached to the block. The loop hooks around a lever tool adjacent to a working end for enhanced attack angle and increased leverage in fastener extraction, prying, and lifting work. Magnets on a tool attachment face assist in aligning and holding the block to the lever tool. End magnets hold fasteners after extraction or before insertion. Recesses in the block contain or retain other working tools.

A deadblow tool, comprising a head with one or more striking surfaces; a handle joined to or molded as one with the head; a plurality of hollow chambers within the tool embodiment; a plurality of freely moveable material partially filling the hollow chambers; and an embodiment in the form of a hammer, mallet, axe, or annular maul. The tool has hollow chambers created as part of the tool embodiment or created separately as chamber cartridges to be inserted into the tool embodiment. The hollow chambers and chamber cartridges vary in size and shape and the freely moveable material varies in density and volume to accommodate mass distribution and the adjustments thereof provide facilitation to further tune the tool balance and strike performance. Construction methods of chamber cartridges and deadblow handles, hammers, mallets, axes, and mauls are also provided.

A power tool is provided including a motor housing; a transmission housing disposed adjacent the motor housing with a gap therebetween; an electric motor including a rotor and a stator mounted within the motor housing; and an intermediate housing disposed between the electric motor and the transmission mechanism. The intermediate housing includes a back wall extending radially adjacent an axial end of the stator and having a through-hole therein through which the motor spindle extends; side walls extending axially from an outer circumference of the back wall internally of the motor housing; and one or more external walls extending substantially-radially outwardly from axial end of the one or more side walls to fill a gap formed between the transmission housing and the motor housing in the axial direction.

An impact tool having a split anvil assembly includes an internal anvil portion fixed inside a housing of the impact tool and an external anvil portion that is removably attached to the internal anvil portion and extends outside of the housing. The external anvil portion includes a retractable pin biased to an extended position to engage the internal anvil portion to secure the external anvil portion to the internal anvil portion and depressed to a retracted position to permit the external anvil portion to be disengaged from the internal anvil portion. The internal anvil portion and the external anvil portion may include respective internal and external grooves that interconnect with each other to link the movement of the internal anvil portion to the external anvil portion.

A tool bushing of a breaking hammer, a tool bushing arrangement, a breaking hammer and a method of mounting a tool bushing of a breaking hammer are disclosed. The tool bushing is a sleeve-like piece having a multi-shouldered outer surface with three or more successive cylindrical portions. The cylindrical portions have different diameters that match with corresponding surfaces of a bushing housing when the tool bushing is mounted. Diameters of the bushing and the bushing housing are dimensioned so that friction forces are generated when the bushing is assembled.

An inner-flanged bushing for a hydraulic breaker is a tubular shape having an inner flange and is made of a steel containing at least 0.55% and less than 0.70% by mass of carbon, at least 0.15% and less than 0.35% by mass of silicon, at least 0.4% and less than 0.9% by mass of manganese, at least 0.4% and less than 1.3% by mass of chromium, and at least 0.10% and less than 0.55% by mass of molybdenum, with the balance being iron and unavoidable impurities. The bushing includes a base region having a hardness of at least 30 HRC and less than 45 HRC, and a quench hardened layer formed on an inner periphery side of the base region to include an inner peripheral surface of a region including the inner flange, the quench hardened layer having a hardness of at least 55 HRC and less than 63 HRC.
