Starrett 52965 Test Indicator Ball Contact Point Carbide

Product Description

The STARRETT 52965 is a carbide ball contact point designed for use with dial test indicators in precision measurement applications. The ball tip measures 0.063 inches (1.60 mm) in diameter, with a contact point length of 5/32 inches (3.97 mm) and a tip diameter of 0.062 inches. The carbide construction provides durability and wear resistance suited to repeated contact with machined surfaces. This contact point is installed by machinists, tool room technicians, and quality control professionals who require accurate surface and runout measurements.

This contact point is intended for use with Starrett 711 Series Last Word Dial Test Indicators. It is a common replacement or supplemental tip for indicator setups in machine shops, inspection departments, and precision manufacturing environments. Its small ball diameter makes it well suited for measurements in confined spaces or on curved surfaces where a standard contact point would not seat properly.

Installation Notes

Contact point replacement is performed by machinists or metrology technicians. Before swapping contact points, ensure the indicator is removed from the magnetic base or fixture arm to avoid accidental movement or damage to the indicator spindle. Use the appropriate wrench size for the contact point stem to avoid overtightening, which can damage the threaded spindle. Handle carbide-tipped points carefully, as carbide is hard but brittle and can chip if dropped on hard surfaces.
