Accuracy is rated at 0.000080 inches, making it suitable for high-tolerance inspection work in machining, engine rebuilding, and mechanical maintenance applications. The gage uses a two-point contact system and a pendulum guide structure that allows the gage to slide into position without binding, improving repeatability and reducing operator error. The included indicator and nine interchangeable anvils are included in the set, allowing coverage across the full measurement range without additional tooling. Machinists, tool-and-die technicians, and mechanical inspectors are the primary users of this instrument.\u003c\/p\u003e\u003cp\u003eThis dial bore gage is used wherever precise bore measurement is required, including engine cylinder bores, hydraulic cylinder housings, pump bodies, and precision machined housings in both production and field service environments. The nine-anvil configuration supports a wide sub-range of bore diameters within the 0.7 to 1.4 inch span, reducing the need for multiple gages in a typical shop setup. The pendulum guide structure allows accurate two-point contact measurement of ovalness and taper within a bore, which is critical for determining wear patterns and serviceability of components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 0.7 to 1.4 inches with 0.000080-inch accuracy\u003c\/li\u003e\n\u003cli\u003eTwo-point contact system for consistent, repeatable bore measurement\u003c\/li\u003e\n\u003cli\u003ePendulum guide structure permits smooth slide of the gage into the bore\u003c\/li\u003e\n\u003cli\u003eSupports ovalness and taper measurement within the bore\u003c\/li\u003e\n\u003cli\u003eIncludes indicator and 9 interchangeable anvils to cover the full range\u003c\/li\u003e\n\u003cli\u003eAccessories included in the set for immediate use out of the box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style precision measurement instrument suitable for use in machine shops, engine rebuild facilities, and mechanical maintenance operations where bore diameters fall within the 0.7 to 1.4 inch range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is a precision measurement tool and does not require installation in the traditional sense, but proper setup and calibration are required before use. Set the gage to the master ring or micrometer setting standard before taking measurements. Handle the indicator and anvil contact points with care to avoid damage that could affect accuracy. Store in the provided case when not in use to protect the instrument from contamination and impact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.7 to 1.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.000080 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Anvils\u003c\/strong\u003e: 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Indicator\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccessories Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.44 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7.32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 16.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.42 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 511-751-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559787430194,"sku":"511-751-20","price":546.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10c81f3cc8d6c12355754cd5988bf29e.jpg?v=1786441077","url":"https:\/\/voomisupply.com\/products\/mitutoyo-511-751-20-dial-bore-gage-0-7-to-1-4-in-9-anvil","provider":"Voomi Supply","version":"1.0","type":"link"}
