Starrett 72452 Ball Contact Point Carbide 0.0315 in

Product Description

The STARRETT 72452 is a carbide ball contact point designed for use with dial test indicators. It features a 0.80 mm (0.0315 inch) ball diameter and a contact point length of 15.88 mm (0.625 inches). The carbide tip provides wear resistance for repeatable, accurate measurements in precision gauging and inspection work. This contact point is installed by machinists, quality control technicians, and toolroom professionals who require reliable indicator accessories for surface, bore, and runout inspection tasks.

This ball contact point is suited for precision measurement applications in manufacturing, machine shops, and inspection environments. It is used when standard contact points do not provide adequate access to a workpiece feature, or when a ball-style tip is needed to reduce line contact on curved or angled surfaces. Compatible system information is listed below.

Installation Notes

Installation is performed by machinists or quality technicians using standard contact point tooling. Power down or lock out any automated equipment before mounting the indicator and contact point to the fixture or spindle. Handle carbide-tipped contact points carefully to avoid chipping the tip against hard surfaces. Verify that the contact point is fully seated and secured before taking measurements.
