ABSTRACT:
A guide for an axially movable hand-held tool, such as a drill, is disclosed. The guide has a base that supports a pivot assembly including a post attachment with a guide post and an angle locator, used with an adjustment shaft for angle cuts. A "U" bracket adjustably supports the post attachment on the guide base. One end of the adjustment shaft is shaped to prevent rotation while permitting reciprocation of the shaft within the "U" bracket. A handle cooperates with the adjustment shaft to clamp the pivot assembly to the "U" bracket and guide base at selected angles and is used to position and control the guide during use. A spring biases the post attachment toward one leg of the "U" bracket for angle selection, location and retention.
