ABSTRACT:
A two-piece depth adjustment assembly for a hand-held power tool. The depth adjustment assembly includes a mounting sleeve which can be snapped onto the housing of the power tool to fix the sleeve relative to the housing and which can also be snapped off the housing. The depth adjustment assembly also includes a locator having external threads engaged with complementary internal threads on the sleeve so that rotation of the locator relative to the sleeve displaces the locator axially forwardly and rearwardly. To maintain the locator in a predetermined angular position relative to the sleeve, the depth adjustment assembly includes indexing means including resilient fingers on the locator and axially extending recesses on the sleeve for releasably housing the fingers. The result is a depth adjustment assembly which does not require an operator to disturb a previously set depth setting when changing tool attachments and which will not slip from the adjusted setting.
