The invention relates to a power drill, having a tool-clamping device that is fastened to a spindle shaft, having a torque clutch that includes an axially movable clutch plate on which an axial force is exerted by a plurality of compression springs that cooperate at least indirectly with an adjusting nut situated on a housing component. The compression springs are accommodated in first recesses embodied in the longitudinal direction of the housing component. A device for axially moving an axial bearing situated on the spindle shaft, is provided at the end of the spindle shaft oriented toward the tool-clamping device. According to the invention, on its side oriented toward the clutch plate, the device for axially moving the axial bearing has at least one actuating section that is situated in a second recess of the housing component and on the side oriented toward the clutch plate, cooperates with an adjusting element for the device.

A multi-stroke powered safety hammer including a cylinder having an end, the cylinder mounted to and extending outwardly from a body to the end, and an impact piston disposed within the cylinder for axial reciprocating movement, the impact piston having a striking surface at a front end thereof. The hammer further includes a mount connected releasably over the end of the cylinder and is configured to receive and releasably secure a base of a tool for reciprocating movement, the base including an end having an impact surface. The end of the cylinder is configured to receive the end of the base for reciprocating movement in confronting relation of the impact surface to the striking surface when the base is received and releasably secured by the mount for reciprocating movement.

A hand held planishing hammer is provided that includes a power unit mounted on a base plate with a handle and powering means that is controllable to produce a hammering action by a combination of a hammer head and slapper to provide flattening, smoothing, and polishing of sheet metal for the aircraft, automobile collision repair, restoration and architectural sheet metal industries.

A hand-held driver device, comprising a solid impact body, configured to provide a user a surface for driving fasteners, an adjustable strap attached to a top surface of the solid impact body for retaining the solid impact body on the user's hand, a pair of inextensible rings attached to the adjustable strap, the pair of inextensible rings laterally opposed to each other and configured to provide a secure attachment point between the adjustable strap and the solid impact body, an adjustment device attached to the adjustable strap for modifying the length of the adjustable strap, an insulating surface integral to the top surface of the solid impact body, which is configured to conform to the shape of the user's hand and provide impact protection to the user's hand during use of the hand-held driver device, and a sacrificial bottom surface integral to the solid impact body, which is configured to make contact with the fasteners.

A decoring hammer for decoring cast workpieces, includes: —a housing; —a striker which is coupled to the housing and which includes a contact surface serving for contact on the cast workpiece to be decored. Moreover, a downholder is formed which is coupled to the housing and which includes a downholder surface serving for contact on the cast workpiece to be decored, wherein the striker is displaceable relative to the downholder.

A hand-held driver device, comprising a solid impact body, configured to provide a user a surface for driving fasteners, an adjustable strap attached to a top surface of the solid impact body for retaining the solid impact body on the user's hand, a pair of inextensible rings attached to the adjustable strap, the pair of inextensible rings laterally opposed to each other and configured to provide a secure attachment point between the adjustable strap and the solid impact body, an adjustment device attached to the adjustable strap for modifying the length of the adjustable strap, an insulating surface integral to the top surface of the solid impact body, which is configured to conform to the shape of the user's hand and provide impact protection to the user's hand during use of the hand-held driver device, and a sacrificial bottom surface integral to the solid impact body, which is configured to make contact with the fasteners.

A hand held planishing hammer is provided that includes a power unit mounted on a base plate with a handle and powering means that is controllable to produce a hammering action by a combination of a hammer head and slapper to provide flattening, smoothing, and polishing of sheet metal for the aircraft, automobile collision repair, restoration and architectural sheet metal industries.

A tool for installing a stud having a plurality of locking keys into a workpiece bore includes a main body, an actuator within the main body, a nosepiece adjacent the main body and having an anvil portion, and a mandrel disposed within the nosepiece. The actuator includes a movable piston, a shaft extending axially from the piston, and a coupler on a shaft end opposite the piston. The mandrel includes a threaded head portion and a body portion, and is releasably secured to the coupler.

A multi-stroke powered safety hammer system includes a hammer having a body, a cylinder within the body, and a piston carried in the cylinder for reciprocal movement therein. The system includes a quick-connect coupling mount on the hammer, the mount having an inner barrel bounding a hollow interior, an outer sleeve for sliding movement over the inner barrel, and an engagement assembly defined by the inner barrel and the outer sleeve for locking an attachment in the interior. The system includes one of many attachments with an engagement portion; when the engagement portion is applied to the quick-connect coupling mount and the hammer is operated, the piston reciprocates to impact the engagement portion. The attachments guide fasteners, remove fasteners, and process materials.

In a method for installing a key locked insert to a workpiece, the workpiece has a hole open to a first surface. The method includes: threading an insert body into the hole; threading a first portion of a mandrel into the insert body; after the threading of the first portion into the insert body, mating a second portion of the mandrel with an actuator; and using the actuator to extend an anvil relative to the mandrel to drive keys of the insert through a thread of the workpiece hole.
