The ball tip measures 0.118 inches in diameter and the contact point length is 0.497 inches, providing the short, accurate reach required for surface deviation and runout measurements. The carbide construction delivers hardness and wear resistance suited to repeated contact against metal workpieces. This contact point is a small but critical component in any metrology or quality-control setup on the shop floor or in a calibration environment. Machinists, quality technicians, and tool room professionals are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis contact point is intended for use with Brown and Sharpe test indicators in inspection, setup, and alignment tasks. Typical applications include checking runout on a lathe, verifying flatness on a surface plate, and aligning a vise or fixture on a machining center. The compact 0.118-inch carbide ball allows access to tight bores and small features where a larger tip would be obstructed. It ships as a single unit, suitable for replacement of a worn or damaged tip on an existing indicator.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide ball tip for long service life under repeated metal contact\u003c\/li\u003e\n  \u003cli\u003e0.118 inch ball diameter enables access to tight-tolerance features\u003c\/li\u003e\n  \u003cli\u003e0.497 inch contact point length suits standard test indicator stems\u003c\/li\u003e\n  \u003cli\u003eSingle-piece replacement unit minimizes indicator downtime\u003c\/li\u003e\n  \u003cli\u003eDesigned specifically for Brown and Sharpe test indicator compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Brown and Sharpe test indicators as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by quality technicians or machinists. Before swapping the contact point, remove the indicator from any active setup and ensure the indicator spindle is at rest. Use the appropriate wrench or contact point tool to avoid side-loading the indicator stem during removal and installation. Overtightening the contact point can damage the indicator thread; snug to finger-tight plus a small turn with the correct tool is the standard practice.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.118 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.497 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Brown and Sharpe Test Indicators\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21-127-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51717251006770,"sku":"21-127-6","price":26.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2c2850ce3ef3c1a875dd6e475090f99.jpg?v=1788537343","url":"https:\/\/voomisupply.com\/products\/spi-21-127-6-ball-contact-point-carbide-0-118-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
