Abstract
A hand-held power tool having a multi-speed transmission and a clutch. The multi-speed transmission and the clutch are coupled to one another via a set of interconnecting tabs that are slidingly engaged to one another and secured with pins to inhibit the withdrawal of the tabs from one another. The clutch may include a clutch member, a unitarily formed clutch plate and a plurality of engagement members. The clutch plate includes an annular plate member and a plurality of leg members that extend generally perpendicularly from the annular plate member and which bias the engagement members into engagement with the clutch member. The clutch member may be coupled to an element of the multi-speed transmission, such as to the ring gear of a planetary gear set, so as to reduce the overall size of the power tool.
