With the Mitutoyo 050083-10 depth base attachment, you turn your standard caliper into a highly stable depth measuring tool. When checking bores, slots, and holes, the narrow base of a standard caliper can easily tilt. This 75 mm long and 12 mm wide base significantly expands your reference surface. The precision-ground contact face sits completely flat against the workpiece, eliminating alignment errors and ensuring repeatable results. Using the integrated clamping screw, you can mount the attachment quickly and securely onto 100 mm, 150 mm, and 200 mm Mitutoyo calipers equipped with a depth measuring rod. It is the practical choice for dependable inspection and quality control.
