It features ball contact points and delivers an accuracy of 0.0008 inches (0.0150 mm), making it suitable for measuring grooves, bores, and other internal features where tight tolerances matter. With a measuring depth of 1.37 inches (35.00 mm), the gage reaches into recessed areas that standard calipers cannot access. It is used by machinists, quality control technicians, and precision measurement professionals who require repeatable, reliable readings on small internal dimensions.\u003c\/p\u003e\n\u003cp\u003eThis gage is built for applications where groove or bore geometry must be verified to close tolerances. The ball contact point design allows the gage to seat accurately inside narrow grooves as small as 0.032 inches wide and up to 0.09 inches deep. It is well suited for inspection tasks in manufacturing, tooling, and general precision metrology work. The compact form factor and dial readout make it practical for use at the machine or on the inspection bench.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAccuracy of 0.0008 inches (0.0150 mm) for high-precision internal measurement\u003c\/li\u003e\n  \u003cli\u003eBall contact point type for accurate seating in grooves and bores\u003c\/li\u003e\n  \u003cli\u003eMeasuring depth of 1.37 inches (35.00 mm) for reach into recessed features\u003c\/li\u003e\n  \u003cli\u003eGroove width capacity of 0.032 inches accommodates narrow internal profiles\u003c\/li\u003e\n  \u003cli\u003eGroove depth rating of 0.09 inches for shallow groove inspection\u003c\/li\u003e\n  \u003cli\u003eTip diameter of 0.60 inches provides stable contact surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision inside measurement gage suitable for general groove and bore inspection applications in machine shop and quality control environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis gage is a handheld measurement instrument and does not require installation in the traditional sense. Before use, verify the gage is zeroed per the manufacturer calibration procedure. Keep contact points clean and free of debris to maintain measurement accuracy. Store in the provided case when not in use to protect the dial mechanism and contact tips from damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy (Decimal Inch)\u003c\/strong\u003e: 0.0008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy (mm)\u003c\/strong\u003e: 0.0150 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point Type\u003c\/strong\u003e: Ball\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Depth (Decimal Inch)\u003c\/strong\u003e: 1.37 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Depth (mm)\u003c\/strong\u003e: 35.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth (Decimal Inch)\u003c\/strong\u003e: 0.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Depth (mm)\u003c\/strong\u003e: 2.30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGroove Width (Decimal Inch)\u003c\/strong\u003e: 0.032 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip Diameter (Decimal Inch)\u003c\/strong\u003e: 0.60 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 13.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 209-935\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51561650422066,"sku":"209-935","price":950.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bfd8be96755519e0204b2739a9fac15.jpg?v=1786467129","url":"https:\/\/voomisupply.com\/products\/mitutoyo-209-935-inside-dial-caliper-gage-ball-contact","provider":"Voomi Supply","version":"1.0","type":"link"}
