The contact point features a 0.063 inch ball diameter and a total contact point length of 5\/32 inches (0.156 inches). The tip diameter measures 0.062 inches. Machined from steel for durability and dimensional stability, this contact point delivers consistent surface contact when sweeping bores, checking runout, or inspecting machined surfaces. It is a replacement or supplementary stylus intended for machinists, toolroom technicians, and metrology professionals who require accurate, repeatable readings in close-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis contact point is sized and threaded to fit the Starrett 711 Series Last Word Dial Test Indicators. It is suited for shop-floor inspection tasks, fixture setups, and machine tool alignment work in both production and toolroom environments. The compact ball geometry allows access to tight features and contoured surfaces where a flat contact would not provide reliable seating. Typical applications include checking concentricity, parallelism, and surface deviation on small or precision-machined components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall diameter of 0.063 inches (1.60 mm) for precise point contact on curved and flat surfaces\u003c\/li\u003e\n  \u003cli\u003eContact point length of 5\/32 inches (3.97 mm) for compact reach in confined measurement areas\u003c\/li\u003e\n  \u003cli\u003eTip diameter of 0.062 inches for accurate seating on fine features\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and dimensional stability under repeated use\u003c\/li\u003e\n  \u003cli\u003eDirect replacement contact point for Starrett 711 Series Last Word Dial Test Indicators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Starrett 711 Series Last Word Dial Test Indicators as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eContact point replacement is typically performed by machinists or metrology technicians using standard indicator wrenches or small open-end wrenches. Zero out or remove the indicator from service before swapping contact points to avoid false readings or stylus damage. Avoid overtightening the contact point, as the threaded shank on precision indicator styli is designed for snug hand-tight seating. Verify zero calibration after installing a new contact point before taking measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.063 inches (1.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 5\/32 inches (3.97 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.062 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0125 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: California Proposition 65\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 70944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540834058546,"sku":"70944","price":24.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bff23e3c2a766d09f13d0c37e4a464c.jpg?v=1785864507","url":"https:\/\/voomisupply.com\/products\/starrett-70944-ball-contact-point-0-063-in-steel-711-series","provider":"Voomi Supply","version":"1.0","type":"link"}
