A work tool includes a housing, a spindle, a motor, a power-transmitting mechanism and a restricting member. The power-transmitting mechanism includes a sun member, a ring member, a carrier member and a planetary roller. One of the sun member and the ring member is configured to move together with the spindle in the front-rear direction relative to the other of the sun member and the ring member. The power-transmitting mechanism is configured to transmit power of the motor to the spindle when the sun member and the ring member relatively move toward each other in response to rearward movement of the spindle and the planetary roller gets into frictional contact with the sun member and the ring member. The restricting member is configured to restrict the planetary roller from moving in the front-rear direction relative to the housing.

Work tool

A rechargeable shear () includes: a motor () having a rotor () that is rotatable relative to a stator (); a motor housing (), which houses the motor (); a grip housing () connected to the motor housing (); a battery-holding housing () connected to the grip housing (); and a shear part () disposed forward of the rotorand operably driven by the rotor (). The motor () may be brushless. The shear part () may be rotatable relative to the motor housing () using a manipulatable ring () and a detent system (-). A light () for illuminating the shear part () and a workpiece being cut thereby may be provided on the grip housing () or the battery-holding housing ().
