Abstract: An accessory tool includes an effector end including a body having first end and a second end opposite the first end, and a base shoulder adjacent the second end. The accessory tool further includes a shank coupled to the effector end. The shank includes a tool engagement portion configured to be received within a tool and having a hexagonal cross section defining a maximum outer width, a first reduced diameter portion disposed adjacent the effector end and defining a minimum outer dimension that is less than the maximum outer width, a fillet extending contiguous from the first reduced diameter portion and flaring outward to the base shoulder, and a second reduced diameter portion disposed adjacent the tool engagement portion and configured to receive a ball detent. The fillet defines a first radius of curvature, and the second reduced diameter portion defines a second radius of curvature.

Abstract: An accessory tool includes an adapter end having a maximum outer dimension, and a shank coupled to the adapter end. The shank includes a tool engagement portion including a cross section having a maximum outer width, a first reduced portion disposed between the tool engagement portion and the adapter end and having a first minimum outer dimension and a first length, and a second reduced portion formed in the tool engagement portion between the first reduced portion and an end of the shank. The second reduced portion is engaged by the tool to secure the shank to the tool, and has a second minimum outer dimension and a second length. The maximum outer dimension is greater than the maximum outer width. The maximum outer width is greater than the first minimum outer dimension and greater the second minimum outer dimension. The first length is greater than the second length.

Abstract: A power tool arbor assembly includes an arbor, an actuating member located at a second end of the arbor, and a friction member located at the second end of the arbor. The friction member is axially movable along the second end of the arbor. The friction member has a first axial position when no power tool accessory is attached to the second end of the arbor. The friction member is moveable toward a first end of the arbor from the first axial position to a second axial position in response to contact between the power tool accessory and the friction member, and the friction member is moveable toward the first end of the arbor from the second axial position to a third axial position when the actuating member is actuated.

Abstract: A drill bit includes a shank, a transition portion, and a body portion defining a plurality of axially stacked, progressively sized steps. The steps include a first step and a terminal step coupled to the transition portion. The first step defines two tip flutes each disposed at a tip flute angle. The body portion defines two body flutes each extending from the first step to the transition portion and disposed at a body flute angle different from the tip flute angle. The drill bit includes a bit tip disposed at the distal end of the body portion and having a chisel edge, a first chisel surface on one side of the chisel edge, and a second chisel surface on an opposite side of the chisel edge. The first chisel surface defines a first relief angle. The second chisel surface defines a second relief angle different from the first relief angle.
