The present invention has a primary trigger, a secondary trigger, an electrical circuit, a screw head, a front side, and a reverse button. The electrical circuit is an internal system that provides electrical power to the present invention. The screw head is a metal component capable of locking into an external screw with a Philips head or flat head. The reverse button is an electrical button that reverses the rotational direction of the screw head. The electrical circuit is positioned within the present invention. The electrical circuit has a battery and a potentiometer. The screw head has a motor that rotates the screw head. The primary trigger is positioned directly next to the secondary trigger for each to easily be compressed simultaneously. The screw head is positioned offset the primary trigger to ensure no interference with the screw head rotation or oscillation.

Inserts disposed in a housing of a pneumatically or hydraulically powered tool having a motor adapted to rotate a drive lug in either of first and second rotational directions. The insert is composed of a material resistive to creep and/or stress relaxation. The insert contacts fasteners applying a clamping force to the tool and remove the housing from the load path of the clamping force, thereby reducing the possibility of fluid leaks.

An electric power tool in one aspect of the present disclosure includes a motor, an impact mechanism, and a control circuit. The control circuit executes a motor control process. The motor control process includes limiting an output of the motor in response to establishment of a preset condition. The preset condition is based on a load applied to the motor.

The drill includes a motor, a spindle rotatable with a rotational force transmitted from the motor, a clutch assembly that disables transmission of the rotational force to the spindle in response to a rotational load on the spindle reaching a release value and including an elastic member that adjusts the release value, and a change ring switchable from a clutch mode in which the clutch assembly is operable to a nonclutch mode in which the clutch assembly is inoperable in response to the change ring operated in a forward rotation direction. In the clutch mode, the elastic member elastically deforms to reduce the release value in response to the change ring operated in the forward rotation direction, and to increase the release value in response to the change ring operated in a backward rotation direction.

An impact tool includes a housing, an anvil extending from the housing, a tool element removably coupled to the anvil, a drive assembly to impart rotational impacts to the anvil, and a detent system supported by the anvil. The detent system includes a detent pin defining a longitudinal center axis and having a notch disposed on only one side of a longitudinal mid-plane containing the longitudinal center axis, and a retaining pin received within the notch. The detent pin is movable relative to the anvil between an extended position and a retracted position, the detent pin is configured to engage the tool element to retain the tool element on the anvil when the detent pin is in the extended position, the detent pin is biased toward the extended position, and the retaining pin engages an end of the notch to limit movement of the detent pin to the extended position.

An anvil for an impact mechanism, where the anvil includes wings that taper at a taper angle of about 5 degrees to about 30 degrees. The anvil may also include a shaft extending from the wings, and a drive end adapted to transfer and apply torque to a work piece. The wings of the anvil also include wing impact surfaces that receive rotational impact forces from a hammer. For example, the hammer contacts and applies torque to the wings of the anvil.

The present invention provides a socket adapter 10 for an impact wrench to prevent a manipulator ring 60 from being intentionally slid, the socket adapter comprising: a main body 11 including a cylinder section 20 having an engagement hole 21 to be installed in an insertion square 90 of the impact wrench, a shank section 40 configured to attach or detach a socket 80, and a drum section 30 positioned between the cylinder section and the shank section; a ball locking mechanism 50 adapted to switch the socket between a locked state where the socket cannot be detached and an unlocked state where the socket can be attached and detached by protrusion and retraction of a ball 51 housed in the shank section; a manipulator ring 60 slidably fitted on the drum section in the axial direction and configured to control the protrusion and retraction of the ball; and a starting resistance imparting means 70 for increasing the starting resistance of the manipulator ring when the manipulator ring begins to slide from a locking position where the ball protrudes to an unlocking position where the ball retracts
