More Information
Summary:A rotary power tool includes a housing and a drive mechanism disposed within the housing. The drive mechanism includes an electric motor, a transmission operably coupled to the electric motor, a spindle operably coupled to an output of the transmission, the spindle configured to transmit torque generated by the electric motor to a working tool bit, and a clutch disposed between the output of the transmission and the spindle. The clutch includes a plurality of spherical rolling elements configured to engage the output of the transmission, a plurality of cylindrical clutch elements, and at least one biasing member configured to bias the cylindrical clutch elements towards the spherical rolling elements. Each of the cylindrical clutch elements includes a length measured parallel to a rotational axis of the spindle and a diameter, and the diameter is greater than the length.
