The stylus contacts the workpiece surface and transmits profile data to the tester, allowing accurate roughness readings in bores, cavities, and other confined geometries that standard styli cannot reliably reach. At 0.5 pounds, the unit is lightweight and straightforward to swap in during field or shop service. Machinists, quality technicians, and precision metrology professionals working in manufacturing or inspection environments are the primary users of this accessory.\u003c\/p\u003e\n\u003cp\u003eThis stylus is intended for surface roughness measurement in deep-hole or recessed-surface scenarios where probe geometry is a limiting factor. It is compatible with surface roughness testers as specified by MITUTOYO and is sold as a single-unit replacement accessory. Typical applications include bore surface inspection on engine components, hydraulic cylinders, valve bodies, and similar precision-machined parts where interior surface finish must meet defined Ra or Rz tolerances.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDeep-hole geometry allows access to recessed and bored surfaces that standard styli cannot reach\u003c\/li\u003e\n  \u003cli\u003eDesigned as a direct replacement accessory for compatible MITUTOYO surface roughness testers\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.5 pounds for easy handling and quick stylus changes\u003c\/li\u003e\n  \u003cli\u003eSingle-unit packaging suitable for stocking as a service or calibration spare\u003c\/li\u003e\n  \u003cli\u003eCompact form factor: 7 inches long, 4 inches wide, 4 inches tall (packaged dimensions)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with MITUTOYO surface roughness testers.

Power down or disable the tester before removing or installing the stylus to avoid damage to the sensing element. Handle the stylus tip with care, as contact damage will compromise measurement accuracy. Follow the tester manufacturer instructions for stylus seating, retention, and post-installation verification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccessory Type\u003c\/strong\u003e: Stylus for Deep Holes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Surface Roughness Testers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12AAE898\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51563740692786,"sku":"12AAE898","price":1308.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/14e8e16a6dde64f8be08a6e0bd3d0ffb.jpg?v=1786502257","url":"https:\/\/voomisupply.com\/products\/mitutoyo-12aae898-surface-roughness-stylus-deep-holes","provider":"Voomi Supply","version":"1.0","type":"link"}
