The contact tip measures 0.1181 inches (3.00 mm) in diameter and is machined from steel for durability and dimensional stability under repeated use. At 0.79 inches in length, this contact point provides the reach needed for surface, bore, and feature runout checks. It is a direct replacement or spare contact tip installed by machinists, tool and die technicians, metrologists, and quality control inspectors working in manufacturing and machine shop environments.\u003c\/p\u003e\n\u003cp\u003eThis contact point is suited for precision dimensional inspection tasks including runout measurement, surface parallelism checks, and bore alignment verification. The ball-style tip allows contact on curved and irregular surfaces where a flat or pointed tip would introduce cosine error or mark the workpiece. It is typically used on inspection benches, CMM setups, and manual surface plate work requiring repeatable, low-force contact.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall-style tip geometry reduces cosine error on curved and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003e3.00 mm (0.1181 inches) ball diameter for fine-feature contact measurement\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance and consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003e0.79 inches contact point length suits standard indicator arm reach\u003c\/li\u003e\n  \u003cli\u003eSold individually, compatible with Mitutoyo 513 Series Dial Test Indicators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Mitutoyo 513 Series Dial Test Indicators as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eContact point replacement is performed by machinists and metrology technicians using standard indicator wrenches or spanner tools. Remove the indicator from any active measurement setup before changing the contact point to avoid damage to the indicator spindle. Ensure the threaded stem is fully seated and snug without overtightening, which can distort the contact stem or damage the indicator body. Follow the indicator manufacturer guidelines for torque and thread engagement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 0.79 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: 0.01 pounds\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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 133197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51562424303922,"sku":"133197","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7550bb99e4dd9d343d658706adb1c6ca.jpg?v=1786476794","url":"https:\/\/voomisupply.com\/products\/mitutoyo-133197-test-indicator-ball-contact-point-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
