Abstract: A bit holder for retaining a tool bit having a groove includes a body defining a bore for receiving the tool bit. The bore includes a first plurality of edges corresponding to an outer profile of the tool bit. The bit holder also includes a collar movably coupled to the body and a lock ring supported within the collar. The lock ring includes an opening having a second plurality of edges, and the lock ring is rotatable between a locked position in which the second plurality of edges is misaligned with the first plurality of edges and an unlocked position in which the second plurality of edges is aligned with the first plurality of edges. The lock ring is rotatable from the locked position toward the unlocked position in response to a rear end of the tool bit engaging the lock ring.

Abstract: A bit retainer is configured to couple a tool bit to an output spindle of a power tool. The bit retainer includes a body coupled for co-rotation with the output spindle about a rotational axis, a collet including a plurality of jaws positioned at least partially within the body, the collet defining a bore between the plurality of jaws configured to receive the tool bit, a wedge surface engageable with the collet, and a sleeve surrounding the body. The sleeve is movable relative to the body to engage the wedge surface against the collet and compress the plurality of jaws around the tool bit.

Abstract: A power tool system including a power tool base having a main body, an electric including an output, and a tool-side attachment mechanism coupled to the main body, the tool-side attachment mechanism having a tool-side locking lug and a tool-side slot adjacent the tool side locking lug. An accessory is configured to be selectively coupled to the power tool base and includes an accessory-side attachment mechanism having an accessory-side locking lug and an accessory-side slot, the accessory-side locking lug selectively engagable with the tool side slot and the accessory-side slot selectively engagable with the tool-side locking lug, a gear arrangement configured to be operably coupled to the output of the electric motor to receive torque from the electric motor, and a tool holder configured to be driven by the gear arrangement. The accessory-side attachment mechanism selectively engages the tool-side attachment mechanism to axially couple the accessory to the power tool base.

Abstract: A tool comprises a housing, an electric motor positioned in the housing, and a drive assembly including an output shaft having a driving end portion. The output shaft extends from the housing such that a tool element for performing work on a workpiece is attachable to the output shaft. A retainer assembly is positioned about an outer surface of the driving end portion. The retainer assembly has a proximal end adjacent to the housing. A deformable retainer ring includes a flexible non-metal material and is positioned about an outer surface of the output shaft between an outer surface of the driving end portion and an interior surface at the proximal end of the retainer assembly
