ABSTRACT:
A portable electric router having a depth of cut adjustment mechanism including an adjustment ring which engages a screw thread on the motor housing and rotationally engages the router base. Rotational engagement of the ring with the base is effected by providing an annular groove on the base and a projection on the ring engaging the groove. The projection is formed with a plurality of pockets each having an opening communicating with the groove. Within each of the pockets is a ball which extends through the opening to contact a wall of the groove and thereby act as a ball bearing.
