The stylus features a zirconia ball tip measuring 10 mm in diameter mounted on an aluminum stem with a 1.20 mm stem diameter. Overall length is 45.6 mm with an effective working length of 37.70 mm (approximately 1.48 inches). The horizontal mounting orientation suits a range of CMM probe configurations. At 0.05 pounds, this lightweight stylus minimizes bending forces during measurement cycles, supporting repeatable contact accuracy on the CMM quill.\u003c\/p\u003e\u003cp\u003eThis stylus is intended for use in dimensional inspection environments where a needle profile is required to access tight features, bores, or narrow slots that a standard ball stylus cannot reach. It is installed and used by CMM programmers, quality technicians, and metrology lab personnel working in manufacturing inspection, tool and die, aerospace, and machined-parts verification settings. The zirconia point material provides wear resistance suitable for repeated contact cycles on ferrous and non-ferrous workpiece surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10 mm zirconia ball tip for wear-resistant point contact\u003c\/li\u003e\n\u003cli\u003eNeedle stylus profile enables access to confined features and narrow geometry\u003c\/li\u003e\n\u003cli\u003e1.20 mm aluminum stem reduces mass and minimizes deflection\u003c\/li\u003e\n\u003cli\u003e37.70 mm effective working length provides reach into recessed surfaces\u003c\/li\u003e\n\u003cli\u003e45.6 mm overall length suits standard CMM probe rack configurations\u003c\/li\u003e\n\u003cli\u003eHorizontal mounting orientation for compatible CMM probe heads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit stylus for CMM probe systems accepting horizontally mounted needle styli with standard threaded stem connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by CMM technicians or metrology personnel. Power down or pause the CMM and retract the probe head to a safe position before changing styli. Use the appropriate stylus wrench and avoid applying lateral force to the stem during installation to prevent bending. Re-qualify the stylus on the reference sphere after installation to establish an accurate tip compensation value before beginning measurement routines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStylus Type\u003c\/strong\u003e: Needle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Zirconia\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 1.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Working Length\u003c\/strong\u003e: 37.70 mm (1.48 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 45.6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Orientation\u003c\/strong\u003e: Horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.5 inches L x 2 inches W x 0.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111900\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 12AAC735\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51564173066546,"sku":"12AAC735","price":656.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_01204df6-3df9-4c3c-9f99-4ae59e172e95.jpg?v=1786513230","url":"https:\/\/voomisupply.com\/products\/mitutoyo-12aac735-cmm-needle-stylus-10mm-ball-zirconia","provider":"Voomi Supply","version":"1.0","type":"link"}
