| description | A power tool includes a housing, a motor having a motor output shaft and located within the housing, the motor being configured to rotate the motor output shaft about a first axis, a drive component having (i) a body attached to the motor output shaft, and (ii) an output drive pin attached to the body, the output drive pin defining a second axis which is offset from the first axis, the body being caused to rotate about the first axis in response to rotation of the motor output shaft about the first axis, and the output drive pin being caused to be eccentrically driven in response to rotation of the body about the first axis, and further the body having a hub and a counterbalance arrangement attached to the hub, the counterbalance arrangement being positioned and configured to offset forces generated by the output drive pin when eccentrically driven, a linkage configured to oscillate in response to the output drive pin being eccentrically driven, and a tool mount configured to oscillate in response to oscillation of the linkage. A method of oscillating a tool is also described. |
