It features a 3.00 mm ruby ball tip mounted on a solid carbide stem, threaded M3 for direct attachment to CMM probe heads and extension systems. The overall length is 50.00 mm, with an effective working length of 43.70 mm and a stem diameter of 2.00 mm. Ruby is the standard material of choice for CMM ball styli due to its hardness, dimensional stability, and low wear rate against common workpiece materials. This stylus is installed by metrology technicians and quality lab professionals performing dimensional inspection on machined parts, tooling, and assemblies.\u003c\/p\u003e\n\u003cp\u003eThis stylus is suited for use in both dedicated quality lab environments and on-machine verification setups where tight dimensional tolerances must be confirmed. The M3 thread is a widely adopted CMM interface standard, making this stylus compatible with a broad range of probe body configurations. It is appropriate for scanning and touch-trigger measurement routines on coordinate measuring machines used in aerospace, automotive, and precision manufacturing environments. The compact 50 mm OAL makes it well suited for feature access in shallow bores, slots, and surface profiles where longer styli would introduce excessive deflection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.00 mm ruby ball tip for precise, low-wear contact measurement\u003c\/li\u003e\n  \u003cli\u003eSolid carbide stem provides high stiffness and minimal deflection during probing cycles\u003c\/li\u003e\n  \u003cli\u003eM3 thread interface compatible with standard CMM probe bodies and extension bars\u003c\/li\u003e\n  \u003cli\u003e50.00 mm overall length with 43.70 mm effective working length for versatile reach\u003c\/li\u003e\n  \u003cli\u003e2.00 mm stem diameter balances rigidity with access to tight geometries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit stylus for CMM probe systems accepting M3 threaded styli.

Use the appropriate stylus changing tool or wrench to achieve a snug, consistent seating torque without over-tightening, which can damage the M3 thread or distort the ruby ball seat. After installation, always perform a reference sphere qualification routine to update the stylus offset in the CMM software before taking measurements. Handle ruby ball styli with care to avoid impact that can chip or crack the ball, which would compromise measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm (1.9685 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEffective Working Length\u003c\/strong\u003e: 43.70 mm (1.7205 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 2.00 mm (0.0787 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBall Material\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStylus Type\u003c\/strong\u003e: Ball\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-5003-0059\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RENISHAW","offers":[{"title":"Default Title","offer_id":67914157785394,"sku":"A-5003-0059","price":80.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffe93902537fde4a3938990154d1760d.jpg?v=1791247565","url":"https:\/\/voomisupply.com\/products\/renishaw-a-5003-0059-cmm-ball-stylus-3mm-ruby-m3","provider":"Voomi Supply","version":"1.0","type":"link"}
