A hammer drill driving bit device for installing an anchor fastener includes a shaft. A first end of the shaft has a first recess extending axially thereinto. The first recess is arcuate and thus is complementary to a head of an anchor fastener, which can be inserted into the first recess. A second end of the shaft is engageable a chuck of a hammer drill so that the shaft is operationally engaged to the hammer drill. The shaft can engage the head of the anchor fastener, such that, with the anchor fastener positioned through a first hole in a first substrate, the hammer drill is positioned to drive the anchor fastener into a second hole in a second substrate. The anchor fastener expands to engage a wall of the second hole to couple the first substrate to the second substrate.

A tool bit for use with a power tool having a chuck and an anvil includes a first end, a second end opposite the first end, a body defining the first end of the tool bit, and a shank coupled to the body and defining the second end of the tool bit. The shank includes a slot formed through the second end. The slot is configured to receive a portion of the chuck to transfer rotational movement from the power tool to the tool bit. The shank also includes a ball detent spaced circumferentially from the slot. The ball detent is configured to receive a locking sphere of the chuck to lock the tool bit with the chuck. The slot is sized to limit insertion of the shank into the chuck, thereby providing a space between the second end of the tool bit and the anvil.

Provided is a tool for mounting a seal in a groove or gap on a wind turbine, the tool including: a roller configured for rolling along the seal and in contact therewith, and a hammer unit configured for exerting a hammering action on the roller to push the seal or a portion thereof into the groove or gap as the roller rolls along the seal, wherein the tool includes a battery powering the hammer unit. Advantageously, the tool combines a rolling action with a hammering action to provide for easy mounting of the seal on the wind turbine.

The invention relates to a method and an apparatus for producing a rod- or pipe-shaped intermediate product provided with an end face (106) from a semi-finished connecting element (102) made of metal, in particular an insertion end of a drill or chisel attached in an axially movable manner in the chuck of a hammer drill, the connecting element (100′) having at least one rotary entrainment surface (162, 164) and at least one locking depression (122, 124), the locking depression (122, 124) being preferably embodied as a locking groove, a semi-finished connecting element (102) being provided, the at least one rotary entrainment surface (162, 164) being formed in the semi-finished connecting element (102) by axially forcing the semi-finished connecting element (102) in the direction of the longitudinal axis (136) of the semi-finished connecting element (102) into a longitudinal die opening (204) of a die (202), or being embossed in the semi-finished connecting element (102) by radially applying at least one movable forming body (206), and the at least one locking depression (122, 124) being embossed by radially applying at least one or multiple forming bodies (206) that are movable in the same die (202).

A method employing an apparatus in conjunction with a hammer-drill to penetrate composite metal and non-metal structure or structures including, for example, thick metal or rebar encountered during concrete, rock or masonry boring operations without requiring a change in drill equipment.

A rotary hammer drill adapter. The rotary hammer drill adapter includes an elongated body having a shank end and a bit end. The bit end is disposed on an opposing end of the elongated body relative to the shank end. The shank end has a plurality of grooves disposed on opposing sides of the elongated body and a plurality of sliding keyways disposed on opposing sides of the elongated body. Each of the plurality of sliding keyways is disposed between a pair of the plurality of grooves. The bit end further includes an interface which is adapted to receive complementary bits.

A hammer drill adapter for driving a drive cleat to join opposed ends of a duct comprising: a first portion generally aligned in a plane; a shaft portion having an elongate axis generally parallel to said plane; the first portion fixed to the shaft portion; an entry surface at a distal end of the first portion; a capture cavity extending through the entry surface; the capture cavity defined proximally by a rear surface and by an opposed lower and upper capture surfaces; the capture cavity also laterally defined by an opposed first capture surface and a second capture surface; the capture cavity sized to house a trailing end portion of a drive cleat; and wherein the shaft portion comprises a connection portion at a proximal end of said shaft portion for fixation within a hammer drill chuck. Also disclosed are methods for use to advance a drive cleat.

A tool for a hydraulic hammer of a work machine is disclosed herein. The tool comprises a spline section and a tool section. The spline section includes a first spline sector including at least six spline grooves and a second spline sector including at least six spline grooves. The first spline sector and second spline sector are separated by a spacer. The tool section diameter is 3.2-4.8 times larger than the spline groove diameter and the tool section diameter is smaller than a spline section diameter.
