Multispeed power tool transmission

A power tool comprising:

• a housing assembly having a handle portion and a body portion;
• a transmission assembly at least partially housed in the housing assembly, the transmission assembly including a reduction gearset assembly, an engagement assembly and a speed selector, the reduction gearset assembly having a first switching stage, a second switching stage and a fixed stage, one of the first and second switching stages being disposed between the fixed stage and the other one of the first and second switching stage with no other transmission stages being disposed between the fixed stage and the other one of the first and second switching stages, the engagement assembly including a follower and a follower spring that biases the follower into engagement with a clutch face that is formed onto a ring gear associated with the fixed stage to resist rotation of the ring gear relative to the housing, the speed selector being coupled to the reduction gearset assembly and including a switch member and an actuator that is movable in response to movement of the switch member to configure the first and second switching stages in at least three overall arrangements;
• and
• a tool holder driven by the transmission assembly, the toll holder being adapted to hold a tool;
• wherein the reduction gearset assembly operates in at least three overall speed reduction ratios, each of the at least three overall speed reduction ratios corresponding to an associated one of the at least three overall arrangements of the first and second switching stages.
