Abstract: A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing on an interior of the housing, and a bearing arranged between the spindle and the sleeve bushing and rotatably supporting the spindle. The bearing has an outer race. The spindle is movable relative to the housing in response to contact with a workpiece, causing the first and second ratchets to engage and the spindle to reciprocate while rotating. The outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

Abstract: A side handle assembly for securing to a neck of a power tool includes a handle configured to be gripped by a user, a rod including a first end to which the handle is coupled and an opposite, second end, a first clamp coupled to the second end of the rod, and a second clamp positioned opposite the first clamp. The neck of the power tool is receivable between the first clamp and the second clamp, with a clamping force applied to the neck, when the first and second clamps are maintained in a clamped state. The side handle further includes a cam lever configured to adjust the first and second clamps between the clamped state and a released state, where the clamping force is removed from the power tool neck.
