A tool including a motor, a transmission including a ring gear including a face having a linear portion and ramps extending a fixed axial distance, a spindle, a setting collar, and a clutch coupled to the transmission. The collar is rotatable between predetermined angular positions including a first position corresponding to a non-torque-limited first operation mode and a plurality of second positions corresponding to different torque output settings of a torque-limited second operation mode. The clutch includes a follower positioned between a clutch washer and the face, and a clutch sleeve coupled to the collar that is movable a variable axial distance from the clutch washer dependent on the collar position. In the first angular position corresponding to the first mode, the fixed axial distance is greater than the variable axial distance, and in the second angular positions, the variable axial distance is greater than the fixed axial distance.

Multi-function handheld electric tool

A multi-function handheld electric tool includes a motor housing receiving a motor, a settable clutch coupled with a speed reduction transmission, transmission housing coupled to the motor housing and having a first housing portion coupled to the motor housing, and a second housing portion extending from the first portion towards a chuck, and a setting collar which is rotatably fit over the second housing portion of the transmission housing and rotatable between a plurality of predetermined angular positions of which at least one corresponds to a non-torque limited first operation mode of the tool and the remaining positions correspond to different torque output levels of a torque limited second operation mode of the tool.
