It features a 5 mm ruby ball tip mounted on a stainless steel stem with an M3 thread interface. The overall length is 31 mm (approximately 1.22 inches), and the stem diameter is 3.5 mm (approximately 0.14 inches). Ruby is the preferred ball material in metrology because of its hardness, low adhesion, and dimensional consistency. This stylus is installed by metrology technicians and CMM operators in quality control and inspection environments.\u003c\/p\u003e\n\u003cp\u003eThe A-5000-7648 is suited for use in dimensional inspection on CMM systems that accept M3 threaded styli. It is appropriate for both single-stylus configurations and as part of a stylus rack or extension assembly. Typical applications include feature measurement on machined components, gauging of bores and surfaces, and incoming or in-process quality inspection in manufacturing facilities. Its compact 31 mm overall length suits tight-clearance measurement scenarios where a longer stylus would create excessive deflection or collision risk.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5 mm ruby ball tip for high hardness and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eM3 thread interface for compatibility with standard CMM stylus systems\u003c\/li\u003e\n  \u003cli\u003e31 mm overall length suits tight-clearance inspection applications\u003c\/li\u003e\n  \u003cli\u003e3.5 mm diameter stainless steel stem provides rigidity with low mass\u003c\/li\u003e\n  \u003cli\u003eRuby point material minimizes wear and adhesion during repeated probing cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-configuration stylus for CMM systems accepting M3 threaded styli.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified metrology technician or CMM operator. Before changing styli, power down or inhibit the CMM probe head to prevent unintended movement. Thread the M3 stylus in by hand first to avoid cross-threading, then tighten to the CMM or extension body according to the system manufacturer's guidance. After installation, perform a qualification routine on the reference sphere before resuming inspection to establish the new stylus tip offset.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 5 mm (0.1969 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 31 mm (1.2205 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEffective Working Length\u003c\/strong\u003e: 31 mm (1.2205 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 3.5 mm (0.1378 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Material\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: RENISHAW\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A-5000-7648\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67907943956786,"sku":"A-5000-7648","price":51.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a10cbc80c4bd0da188370fbf3663231.jpg?v=1791181959","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5000-7648-cmm-ball-stylus-5mm-ruby-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
