It replaces the standard contact point to provide a spherical measuring tip suited for surfaces that require a rolling or curved contact rather than a flat or sharp point. The ball tip measures 0.078 inches in diameter and the overall contact point length is 2.75 inches. Carbide construction delivers high wear resistance, making this contact point appropriate for repeated measurements in production or inspection environments. Metrology technicians, machinists, and quality control personnel are the primary users.\u003c\/p\u003e\u003cp\u003eThis contact point is used in applications where precise runout, surface, or bore measurements are taken with Interapid test indicators. It suits inspection setups on machine tools, surface plates, and CMM fixtures in both shop-floor and controlled metrology environments. The 2.75 inch length provides added reach for setups where the indicator body must be set back from the workpiece. The carbide tip holds its geometry longer than steel under continuous production use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide ball tip resists wear during high-cycle inspection use\u003c\/li\u003e\n\u003cli\u003eBall diameter of 0.078 inches suits curved surface and bore measurements\u003c\/li\u003e\n\u003cli\u003eContact point length of 2.75 inches provides extended reach for deep or offset setups\u003c\/li\u003e\n\u003cli\u003eDesigned for use with Interapid test indicators\u003c\/li\u003e\n\u003cli\u003eReplaces standard contact points without additional hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Interapid test indicators as stated by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContact point installation and replacement is performed by machinists or metrology technicians. Thread the contact point into the indicator spindle by hand until snug, then tighten only as specified by the indicator manufacturer to avoid damaging the spindle thread. Do not overtighten carbide-tipped contact points, as carbide is brittle and may fracture under excessive side load or torque. Verify indicator calibration after any contact point change before returning the instrument to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.078 inches (2.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1 inch H x 0.25 inch W x 0.25 inch L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21-066-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51691808686386,"sku":"21-066-6","price":30.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/501ff00b034822a6e8bc81030a096696.jpg?v=1788289994","url":"https:\/\/voomisupply.com\/products\/spi-21-066-6-ball-contact-point-carbide-for-interapid","provider":"Voomi Supply","version":"1.0","type":"link"}
