Abstract: A belt sander for sanding a workpiece and defining a center of gravity within a first plane. The belt sander includes a housing, a handle defining a second plane, and a drive unit disposed within the housing. The drive unit includes a motor disposed adjacent a first sidewall of the housing, a pulley system disposed adjacent a second sidewall of the housing opposite the first sidewall, and a transmission disposed between the motor and the pulley system. The belt sander further includes a belt drive system driven by the drive unit and including a drive wheel, a driven wheel, and a platen. The platen defines a third plane extending perpendicular therefrom. The transmission and pulley system are disposed on one side of the first plane and the motor is disposed on an opposite side of the first plane. The motor is intersected by the second and third planes.

Abstract: A bit retention assembly, for securing a tool bit to a spindle of a rotary hammer, includes a plurality of detent members movable in unison from a locking position to an insertion position in response to insertion of the tool bit within the spindle, a biasing member configured to bias the detent members toward the locking position, and a collar movable along the spindle between a first axial position and a second axial position. The collar has an annular wall at least partially defining a pocket. A first end of the biasing member is received within the pocket when the detent members are in the locking position such that the first end of the biasing member is radially constrained by the annular wall.
