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.

An apparatus for punching an anchor bolt insertion hole is disclosed. The apparatus enables punching work for forming the anchor bolt insertion hole, of which the bottom side is wider than an inlet, on a panel surface for constructing a concrete structure to be performed regardless of the skill of a worker. During operation, the apparatus provides the movement direction of a hammer drill into the vertical direction and the inclination direction so as to enable precise punching work, and doubly arranges springs, which are elastic devices for adjusting the movement range of the hammer drill, so as to uniformly maintain the angle and size for cutting a wall such that a cross-sectional diameter is large at a portion adjacent to the bottom of the anchor bolt insertion hole.

A universal chisel attachment is an apparatus designed to convert the torque generated by an electric tool into a reciprocal linear motion to drive a chisel member. The apparatus includes a socket adapter, a chisel assembly, a hammering cam mechanism, and a tubular housing. The socket adapter enables the rotational connection of the hammering cam mechanism to a mounting mechanism of the electric tool. The socket adapter also enables the apparatus to be secured to the electric tool. The hammering cam mechanism converts the torque generated by the electric tool to a reciprocal linear motion of the chisel assembly. The chisel assembly enables the carving or cutting of the target object with the apparatus. The tubular housing enables the unobstructed operation of the hammering cam mechanism during operation. The tubular housing also safely retains all the moving components of the hammering cam mechanism to protect the user during operation.

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.

An electrically driven orthopedic impactor may include an adapter for interfacing between the orthopedic impactor and a surgical implement. The adapter may have a first surface that transmits a forward impact energy and a second surface that transmits a reverse impact energy. The adapter can connect to the surgical implement and to the orthopedic impactor without the use of external tools. The adapter may connect to the orthopedic impactor via a pushing motion and may disconnect from the orthopedic impactor via a reciprocal sleeve. A sensor can communicate a spatial orientation of the adapter with respect to at least one reference point that is not located on the adapter or the orthopedic impactor. A communication device may transmit information to the orthopedic impactor related to frequency or impact energy settings based on a type of surgical implement attached to the adapter.

The present disclosure generally relates to quick change attachments for a pneumatic percussive tool. The attachments convert a pneumatic percussive tool, such as an air impact tool with proximal attachment means, which has a “pushing” force, into a pneumatic percussive tool having a “pulling” force. Once attached to the pneumatic percussive tool, the attachments also provide a quick change feature for allowing “pulling” tools to be simply and easily removed and replaced.

Systems and methods for management of material stresses present at transitions between facets of an anvil and the anvil shaft are described. In one aspect, an apparatus includes an impact tool anvil extending along an axis of extension and having a faceted drive end and a shaft body which is connected to the faceted drive end through a transition region that couples respective faces of the faceted drive end to the shaft body, the transition region including a sweeping radius surface having a first axial end and a second axial end, the first axial end connected to a respective face of the faceted drive end, the first axial end having a tangency with the respective face of the faceted drive end; and an angular transition having a slope that radially rises from the second axial end of the sweeping radius surface to the shaft body.

An apparatus and method for latching a hammer of an impact tool, the hammer being displaceable along a cam shaft between a latched or retracted position and an impact position at which the hammer impacts an anvil. The apparatus can include one or more latching bodies, a portion of the one or more latching bodies being positioned within the hammer groove when the hammer is at the latched position, and removed from the hammer groove when the hammer is to be released from the latched position. The apparatus can also include an actuator sleeve that is configured to retain at least the portion of the one or more latching bodies within the hammer groove when the actuator sleeve is at the first position, and accommodate removal of the portion of the latching bodies from the hammer groove when the actuator sleeve is at a second position.

An oxygen sensor socket kit provides an air impact driver and at least one slotted socket forming an annulus forming an inside surface with a plurality rectangular flats parallel to and symmetrically arranged around a central axis. The slot is slot formed through the socket sidewall positioned in place of one or a portion of one of the rectangular flats. An outer surface incorporates at least one radially offset protrusion forming a wing body and having a planar striking surface that lies along a radial projection from the central axis on a plane that intersects central axis. A striking surface forms one or more recesses of a concave shape to receive in a rounded tool tip an air impact driver. The driver has an offset distal portion having an angular offset sufficient to allow a direction of an impact force directly laterally offset from a centerline of the output shaft.
