The side handle assembly includes a clamp configured to secure the side handle assembly to the power tool, the clamp coaxially aligned with a working axis of the power tool, and a handle coupled to the clamp. The handle includes a base coupled to the clamp, a first grip portion coupled to the base, a second grip portion coupled to the base and movable relative to the first grip portion in a direction parallel to the working axis, and a damping element located between the first grip portion and the second grip portion to attenuate vibration from the power tool along the working axis.
