A precise adjustment indicator holder in which a position indicator is carried with respect to a work tool and a work piece. The indicator holder connects to the quill of the work tool, such as a machine tool, or other supporting device and is comprised of a pair of arms which are pivotally connected to one another and movable in planes parallel to and relative to one another. The arms are provided with abutments to limit the degree of movement such that precise final adjustment of the positioning of the work tool can be achieved.
