A tool bit assembly includes a tool bit having a shaft with a first working region disposed at a first end of the shaft and a first reduced diameter portion proximate the working region and disposed between a first shoulder and a second shoulder. A floating sleeve has a rear portion with a pair of opposed window openings, a front portion supporting a magnet, and a pair of balls, with each ball disposed in one of the window openings. The floating sleeve is receivable over the tool bit with the magnet proximate the first working regions and the balls received in the first reduced diameter portion to allow the floating sleeve to move between a first position in which the balls abut the first shoulder and a second position in which the balls abut the second shoulder.

A fastener driving tool includes a shaft with a working region disposed at a first end of the shaft and configured to drive a fastener, a shank portion disposed proximate a second end of the shaft and configured to couple the shaft to a power tool, and a reduced diameter torsion zone disposed between the shank portion and the working region, the torsion zone extending from a first shoulder closer to the working region to a second shoulder closer to the shank portion. A length (L) and a radius (c) of the torsion zone have been optimized so that approximately half of breakages occur in the working region and approximately half of breakages occur in the torsion zone.

Fastening tools with floating magnet sleeves

A bit holder assembly for a rotary hand or powered tool, includes a body having a hex shank at its rearward end and a retraction collar slidably disposed on the body. The body has a coaxial hex socket formed therein to allow a tool bit to be inserted thereinto. A coil spring biases the retraction collar forwardly and biases a retaining clip toward the bottom of an angular slot formed in the body. The bit is removed by sliding the retraction collar rearwardly, to compress the coil spring and allow the retaining clip to retract back up the slot. A ring magnet is disposed at the forward end of the retraction collar to magnetize a fastener to retain the fastener to the bit.

Fastener tool assemblies

A drill bit has a shank portion having a plurality of SDS-type slots, a cutting portion comprising at least one cutting flute, and an intermediate portion connecting the shank to the cutting portion, the intermediate portion including at least one longitudinal slot. A depth gauge includes a body configured to receive the drill bit, a retention mechanism coupled to the body and having an inward projection to removably couple the body to the at least one additional slot in the drill bit, and a cap coupled to the body such that the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a predetermined depth, wherein the cap is movable relative to the body among a plurality of positions, wherein each of the plurality of positions corresponds to a different predetermined drilling depth.

A right angle attachment for use with a power tool that includes a housing having a handle portion and a gear case attached to the handle portion and supporting first and second right angle gears wherein the first right angle gear is driven by an input shaft that is connected to the drill and the second right angle gear has an opening therein for receiving a hex bit directly therein. A floating magnet head can surround the hex bit to aid in fastener retention and can be movable out of proximity of the hex bit to facilitate easy removal of the hex bit for replacement. An additional magnet can be disposed within the gear case at the base of the hex bit in order to magnetize the hex bit and further enhance the retention of the fastener therein.

A dust collector is disclosed for use with a drill bit or a depth stop that is coupled to a drill bit. The dust collector includes a rear attachment portion configured to be axially fixed to a drill bit or to a drill bit depth stop that is axially fixed to a drill bit. An intermediate non-collapsible portion is attached to a front end of the rear attachment portion. The intermediate non-collapsible portion defines a dust-collecting pocket and is structured to inhibit collapse as the drill bit is inserted into a workpiece. A front collapsible portion is attached to a front end of the intermediate non-collapsible portion and at least partially collapses as the drill bit is inserted into a workpiece.

A depth gauge for use with a drill bit includes a body configured to receive a drill bit, a retention mechanism coupled to the body and configured to removably couple the body to the drill bit, and a cap configured to be removably coupled to the body. The cap can be coupled to the body in one of a first position relative to the body where the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a first depth, and a second position relative to the body where the cap contacts the workpiece surface to prevent the drill bit from entering the workpiece more than a second depth that is different from the first depth.

A drill bit has a shank portion having a plurality of SDS-type slots, a cutting portion comprising at least one cutting flute, and an intermediate portion connecting the shank to the cutting portion, the intermediate portion including at least one additional slot. A depth gauge includes a body configured to receive the drill bit, a retention mechanism coupled to the body and having an inward projection to removably couple the body to the at least one additional slot in the drill bit, and a cap coupled to the body such that the cap contacts a workpiece surface to prevent the drill bit from entering the workpiece more than a predetermined depth, wherein the cap is movable relative to the body among a plurality of positions, wherein each of the plurality of positions corresponds to a different predetermined drilling depth.
