The stylus features a zirconia ball tip measuring 10 mm in diameter mounted on a 1.2 mm diameter aluminum stem. Overall length is 45.6 mm, with an effective working length of 37.70 mm (approximately 1.48 inches). The horizontal mounting orientation makes it well suited for reaching into bores, slots, and recessed features that standard vertical styli cannot access. Metrology technicians and quality control professionals install this stylus when inspecting complex part geometries requiring a low-profile, side-access probe configuration.\u003c\/p\u003e\n\u003cp\u003eThis stylus is intended for CMM inspection setups in precision manufacturing, aerospace, automotive, and general metrology environments. Its needle configuration allows access to features with tight clearances where a conventional ball stylus would not fit. The zirconia ball tip provides a hard, wear-resistant contact surface suited for repeated high-cycle inspection routines on ferrous and non-ferrous workpieces. The lightweight aluminum stem helps minimize deflection and keeps the stylus assembly mass low, which is important for maintaining measurement accuracy on sensitive CMM heads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e10 mm diameter zirconia ball tip for wear-resistant, repeatable contact\u003c\/li\u003e\n  \u003cli\u003eNeedle stylus type enables horizontal access to recessed and hard-to-reach features\u003c\/li\u003e\n  \u003cli\u003e1.2 mm stem diameter supports tight-clearance inspection applications\u003c\/li\u003e\n  \u003cli\u003eLightweight aluminum stem reduces deflection and minimizes probe head loading\u003c\/li\u003e\n  \u003cli\u003e45.6 mm overall length with 37.70 mm effective working length\u003c\/li\u003e\n  \u003cli\u003eHorizontal mounting orientation for side-access CMM measurement setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement CMM needle stylus compatible with coordinate measuring machine stylus systems that accept standard horizontal-mount needle styli. Verify thread size and mounting interface on your CMM probe head before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCMM styli should be installed by a qualified metrology technician familiar with the probe system in use. Power down or place the CMM in a safe parked position before changing styli to prevent accidental probe crashes. Avoid touching the zirconia ball tip with bare hands, as surface contamination can affect measurement accuracy. After installation, perform a full stylus qualification routine on the CMM to re-establish the tool offset before taking production measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eOverall Length\u003c\/strong\u003e: 45.6 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\u003eStem Diameter\u003c\/strong\u003e: 1.2 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\u003eMounting Orientation\u003c\/strong\u003e: Horizontal\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\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: 12AAB409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51564045467954,"sku":"12AAB409","price":524.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52fc17d8181fef50dd0377725e249a1e.jpg?v=1786509444","url":"https:\/\/voomisupply.com\/products\/mitutoyo-12aab409-cmm-needle-stylus-10mm-ball-zirconia","provider":"Voomi Supply","version":"1.0","type":"link"}
