A power tool comprising: a housing that defines a handle; a motor coupled to the housing; a trigger coupled to the housing and configured to control operation of the motor; a multi-speed transmission configured to transmit rotary power between the motor and an output spindle of the power tool, the multi-speed transmission comprising a plurality of planetary stages including a first stage and a second stage that receives rotary power from the first stage, the first stage having a first internally toothed gear element, the second stage having a second internally toothed gear element; and a torque clutch that limits torque output from the multi-speed transmission to the output spindle, the torque clutch including a clutch member having a clutch profile, a follower non-rotatably coupled to the housing, and a clutch spring arranged to bias the follower into engagement with the clutch profile to resist rotation of the clutch member; characterised in that the torque clutch is configured to alternatively ground the first and second internally toothed gear elements to the housing through the torque clutch based on a speed ratio setting of the multi-speed transmission, the clutch member having a first set of clutch teeth and a second set of clutch teeth, the first set of clutch teeth being configured to couple to a corresponding set of teeth formed on the second internally toothed gear element to ground the second internally toothed gear element to the housing, the second set of clutch teeth being configured to couple a corresponding set of teeth formed on the first internally toothed gear element to ground the first internally toothed gear element to the housing. a housing that defines a handle; a motor coupled to the housing; a trigger coupled to the housing and configured to control operation of the motor; a multi-speed transmission configured to transmit rotary power between the motor and an output spindle of the power tool, the multi-speed transmission comprising a plurality of planetary stages including a first stage and a second stage that receives rotary power from the first stage, the first stage having a first internally toothed gear element, the second stage having a second internally toothed gear element; and a torque clutch that limits torque output from the multi-speed transmission to the output spindle, the torque clutch including a clutch member having a clutch profile, a follower non-rotatably coupled to the housing, and a clutch spring arranged to bias the follower into engagement with the clutch profile to resist rotation of the clutch member; characterised in that the torque clutch is configured to alternatively ground the first and second internally toothed gear elements to the housing through the torque clutch based on a speed ratio setting of the multi-speed transmission, the clutch member having a first set of clutch teeth and a second set of clutch teeth, the first set of clutch teeth being configured to couple to a corresponding set of teeth formed on the second internally toothed gear element to ground the second internally toothed gear element to the housing, the second set of clutch teeth being configured to couple a corresponding set of teeth formed on the first internally toothed gear element to ground the first internally toothed gear element to the housing.
