The contact point features a 0.078 inch ball diameter and an overall contact point length of 0.9 inches. Carbide construction provides wear resistance and dimensional stability during repeated use, making it suitable for high-cycle inspection routines on the shop floor or in quality control environments. Metrology technicians and machinists use this style of contact point when measuring small bores, grooves, or surfaces where a standard stylus tip would not provide adequate contact geometry.\u003c\/p\u003e\u003cp\u003eThis contact point is intended for use with Mitutoyo test indicators. It suits inspection tasks in machine shops, tool rooms, and manufacturing quality departments where accurate, repeatable surface contact is required. The ball-style tip is commonly used when measuring curved or contoured surfaces, as the spherical geometry maintains a consistent contact footprint regardless of approach angle within the working range of the indicator.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide ball tip for extended wear life and dimensional accuracy\u003c\/li\u003e\n\u003cli\u003e0.078 inch (2.00 mm) ball diameter suits fine-detail measurement tasks\u003c\/li\u003e\n\u003cli\u003e0.9 inch contact point length provides reach for recessed features\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct replacement or spare for Mitutoyo test indicator setups\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.1 pounds for easy handling and storage\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Mitutoyo test indicators.

Before swapping contact points, remove the indicator from any active fixture and ensure it is not under load. Use the appropriate wrench or spanner to avoid over-torquing the contact point stem, which can damage the indicator spindle thread. Handle carbide tip components carefully to prevent chipping, which will affect measurement accuracy.\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: 0.9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTip Diameter\u003c\/strong\u003e: 0.078 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1 inch H x 0.25 inches W x 0.25 inches 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: 20-306-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51713453949234,"sku":"20-306-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f1e45c9c884f3a0443858db8c2463b43.jpg?v=1788493810","url":"https:\/\/voomisupply.com\/products\/spi-20-306-7-ball-contact-point-carbide-0-078-in","provider":"Voomi Supply","version":"1.0","type":"link"}
