Classification: CPC B | IPC B

Claim 19:
20. A power tool, comprising:
a motor;
a carrier configured to be rotatable by the motor;
a pin retained on the carrier;
an input gear,
a first planetary gear retained on the pin and having a first number of teeth;
a second planetary gear (i) having a second number of teeth different from the first number of teeth and (ii) configured to be rotatable via the input gear in a same rotational direction as the first planetary gear,
a first internal gear configured to mesh with the first planetary gear;
a second internal gear configured to mesh with the second planetary gear; and
a locking member configured to disable rotation of either the first internal gear or the second internal gear,
wherein the first planetary gear, the second planetary gear, the first internal gear, the second internal gear and the pin are configured such that a first relative angular velocity between the first planetary gear and the second planetary gear is different than a second relative angular velocity between the second planetary gear and the pin.
