Abstract
A power tool includes a housing, a motor that is disposed within the housing and defining a first axis, and a tool holder driven to oscillate about a second axis by the motor. The second axis is perpendicular to the first axis. The power tool also includes a vibration dampening assembly with a counterweight that is configured to reciprocate along a third axis that is perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis.

A power tool comprising:
- a housing;
- a motor disposed within the housing and defining a first axis;
- a tool holder driven to oscillate about a second axis by the motor, the second axis being perpendicular to the first axis;
- and
- a vibration dampening assembly including a counterweight configured to reciprocate along a third axis perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis.

A power tool comprising:
- a housing;
- a motor disposed within the housing and defining a first axis;
- a tool holder driven to oscillate about a second axis by the motor, the second axis being perpendicular to the first axis;
- a drive mechanism configured to convert torque from the motor to an oscillating movement of a tool accessory received by the tool holder;
- and
- a vibration dampening assembly including a counterweight configured to reciprocate along a third axis perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis.

A power tool comprising:
- a housing;
- a motor disposed within the housing and defining a first axis;
- a tool holder driven to oscillate about a second axis by the motor, the second axis being perpendicular to the first axis;
- and
- a vibration dampening assembly including
- a case supported by the housing,
- a counterweight positioned within the case, the counterweight configured to reciprocate along a third axis perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis,
- a first spring arranged between the case and the counterweight, the first spring biasing the counterweight in a first direction, and
- a second spring arranged between the case and the counterweight, the second spring biasing the counterweight in a second direction opposite the first direction;
- wherein the first and second springs bias the counterweight toward a neutral position within the case.
