A clutch arrangement for use in a power tool having a multi-speed transmissi on assembly. The clutch arrangement includes a clutch member and a follower member. The clutch member is coupled to a member of the transmission assembl y that is proximate the torsional input of the transmission assembly and which must be in a non-rotating position to permit the transmission assembly to perform a torque multiplication operation. The follower member is biased int o engagement with the clutch member to inhibit relative rotation therebetween. As the clutch member and the transmission member are coupled to one another, the transmission assembly is able to perform a torque multiplication operation. When, however, the torsion that is exerted onto the clutch member is sufficient to overcome the fractional engagement between the follower and clutch members, the clutch member, and the transmission member, rotate, thereby inhibiting the capability of the transmission to continue to perform the torque multiplication operation.
