More Information
Summary:A power tool includes a housing, a drive mechanism supported within the housing, a spindle operatively coupled to an output of the drive mechanism such that torque from the drive mechanism rotates the spindle about an axis, and a clutch assembly configured to selectively limit torque transfer from the drive mechanism to the spindle. The clutch assembly includes a plurality of rolling elements, a biasing member configured to bias the plurality of rolling elements into engagement with the output of the drive mechanism, and a sleeve movable along the axis to adjust a torque limit of the clutch assembly by varying a preload of the biasing member. The sleeve is made of a high-temperature, engineering thermoplastic.
