Multi-function handheld electric tool

A power tool comprising:

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