Abstract: A torque transfer assembly for an impact bit holder may include a jacket operably coupled to a driven body having a driven end configured to interface with a bit, and a multi-start thread assembly operably coupling the jacket to a drive body having a drive end configured to interface with a powered driver. The torque transfer assembly may be disposed between the drive body and driven body and may be configured to transfer torque between the drive body and the driven body.

Abstract: An electrically isolated adapter may include a drive body made of first metallic material extending along a common axis, a driven body made of a second metallic material extending along the common axis, and an isolation assembly formed of insulating material disposed between the drive body and the driven body. The drive body may include a drive head configured to interface with a socket or fastener. The insulating material has a resistance to electrical current that is higher than the resistance to electrical current of at least one of the first metallic material and the second metallic material. The driven body may include a drive receiver configured to interface with a protrusion of a driving tool. A portion of one of the drive body or the driven body is received inside a portion of the other of the drive body or the driven body such that the drive body and driven body overlap each other along the common axis.

Abstract: A bidirectional extraction socket may include a driven end configured to receive drive power from a driving tool, a drive end configured to interface with a fastener, and a body portion extending between the driven end and the drive end about an axis of the extraction socket.

Abstract: A power tool (130) may include an end effector (200) configured to engage an object to be worked by the tool, a power unit (230), a drive assembly (210) configured to drive the end effector responsive to application of input power thereto, and a motor (220) configured to supply the input power to the drive assembly selectively based on operation of a power control assembly (240) that controls coupling of the motor to the power unit. The power control assembly includes a trigger (300) having a full range of motion (310) between a rest position and an actuated position. The power control assembly further defines a transition point (316) between a first region (312) and a second region (314) of the full range of motion. The power control assembly includes a first biasing assembly (330) that opposes movement of the trigger in the first region, and a second biasing assembly (340) that opposes movement of the trigger at least at the transition point.

Abstract: A rotating power tool is provided. The rotating power tool may include a bevel gear set having a bevel gear and a conductive spiral disposed on the bevel gear. The conductive spiral may be configured to, in response to the bevel gear deforming due to a torque being applied to the bevel gear, change a resistance of the conductive spiral. The rotating power tool may further include an antenna electrically connected to the conductive spiral. The antenna may be configured to emit an output signal at a frequency that is based on the resistance value of the conductive spiral. The frequency of the output signal may be indicative of an amount of torque being applied to the bevel gear.
