    摘要: A tool bit comprising a shaft having a shank at a first end and a working region disposed at a second end. The shaft has a shaft section between said shank and the working region with a reduced diameter region disposed between two shoulders. The reduced diameter region provides a torsion zone that allows the shaft section to twist to absorb forces while the tool bit is being used to drive a fastener. A ring magnet assembly is movably disposed at the second end of the shaft to magnetize a fastener to retain the fastener to the working region of the tool bit.

    摘要: A bit holder assembly for a rotary tool, includes a body having a shank at its rearward end and a retraction collar slidably disposed on the body. The body has a coaxial socket formed therein to allow a tool bit to be inserted thereinto and an opening formed in the body in communication with the socket. A coil spring biases the retraction collar forwardly. A retainer is held in a bottom of the opening by the retraction collar or the coil spring. A ring magnet is disposed at the forward end of the retraction collar. The retraction collar is moveable among a neutral position, a retracted position rearward of the neutral position and a forward position forward of the neutral position. In the neutral position, the retainer engages the tool bit to retain the tool bit in the socket. In the retracted position, the retraction collar compresses the coil spring and allows the retainer to retract back up the opening to disengage the retainer from the tool bit and allow removal of the tool bit from the socket. The retraction collar is configured to float forward from the neutral position to the forward position to allow the ring magnet to engage and magnetize a fastener to retain the fastener to the tool bit.

    摘要: A tool (10, 210, 310, 410) for driving threaded fasteners includes a tool bit (12, 212, 312, 412) extending along a longitudinal axis and including a rear shank (16) of polygonal cross section, a front working end (18, 218, 318, 418), and an intermediate portion (20, 220, 320, 420) having a front shoulder (28, 36), a rear shoulder (20, 30), and a reduced diameter annular groove (32). A floating magnet sleeve (14) receivable over the tool bit (12, 212, 312, 412) includes a tubular body (50), retention member (58) projecting radially inward from a rear end (48, 54) of the body (50), and a magnet (60) disposed at a front end (46, 52) of the body (50). The sleeve (14) is axially moveable by a float distance between rearward and forward positions such that the magnet (60) can engage a fastener head coupled to the working end (16, 18) as the sleeve (14) approaches the forward position. The float distance is less than a tip (19) distance between a front end (46, 52) of the magnet (60) and a front tip (19) of the working end (16, 18) when the sleeve (14) is in the rearward position.

    摘要: A power tool accessory system for a power tool includes a power tool accessory with a housing, an input shaft rotatably driven by a power tool, and a working tool driven to perform an operation upon rotation of the input shaft. The system also includes a brace configured to removably couple the housing to the power tool while the input shaft rotates. The brace includes a clamp assembly configured to be fixedly coupled to a base of the power tool handle, and an arm assembly with a first end portion configured to be coupled to the housing and a second end portion configured to be coupled to the clamp assembly. The second end portion is removable from the clamp assembly while the clamp assembly remains fixedly coupled to the power tool to enable removal of the power tool accessory from the power tool.
