Abstract
A hammer drill/driver with a motor having an output member, a planetary transmission, a clutch assembly and a clutch bypass. The planetary transmission, which includes a ring gear, receives rotary power from the output member and produces a rotary output. The clutch assembly has a clutch profile, which is coupled to the ring gear, and a first pin assembly having a first follower, a first pin member and a first spring that biases the first follower into contact with the clutch profile. The clutch bypass has a bypass profile, which is coupled to the ring gear, and second pin assembly having a second follower, a second pin member, a second spring, which biases the second follower away from the bypass profile, and a third spring, which biases the second follower away from the second pin member. A method for operation of a hammer drill/driver is also provided.
