ABSTRACT:
A power tool motor housing rotates a spindle assembly which moves axially within limits of adjusting nuts. A sensing sleeve maintains an axially fixed position with respect to the drive housing and thus with respect to a depth adjustment for controlling axial movement of the spindle. A foot piece moves along the sleeve as an adjusting nut is rotated on the sleeve to adjust stand off without changing preset depth of cut. A swivel assembly connects the sensing sleeve to the power housing so that the power housing may be rotated or indexed without changing the distance between the sensing sleeve and the depth adjustment.
