1. A soft-stop transmission for use in a power tool, the transmission comprising:
a first component configured to receive torque from a motor of the power tool to rotate the first component in a first rotational direction;
a second component connectable to an output of the power tool, wherein the second component is configured to rotate in the first rotational direction in unison with the first component, and wherein the second component is configured to rotate in the first rotational direction relative to the first component in response to angular deceleration of the first component; and
a damping element positioned between the first component and second component, wherein the damping element is configured to bias the first component in the first rotational direction and the second component in an opposite, second rotational direction.
