It uses a two-point contact system and a pendulum guide structure that allows the gage to slide into alignment within the bore, producing consistent, repeatable readings. Accuracy is rated at 0.0001 inches, making it suitable for precision inspection of machined bores, cylinders, and housings. The unit comes with 11 interchangeable anvils to cover the full measurement range. A dial indicator is included, and accessories are bundled in the package. This tool is used by machinists, quality control technicians, and precision measurement professionals.\u003c\/p\u003e\u003cp\u003eThe 511-753-20 is suited for inspection work in machine shops, manufacturing facilities, and maintenance environments where internal bore measurement is required. The ovalness and taper measurement capability makes it useful for evaluating bore geometry beyond simple diameter checks. The included anvils allow a single gage to span a wide diameter range without additional tooling. It is appropriate for both production-floor spot checks and detailed metrology tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range: 2 to 6 inches internal bore diameter\u003c\/li\u003e\n\u003cli\u003eAccuracy: 0.0001 inches\u003c\/li\u003e\n\u003cli\u003e11 interchangeable anvils included for full range coverage\u003c\/li\u003e\n\u003cli\u003eTwo-point contact system for consistent bore alignment\u003c\/li\u003e\n\u003cli\u003ePendulum guide structure allows natural centering during measurement\u003c\/li\u003e\n\u003cli\u003eCapable of measuring ovalness and taper in addition to diameter\u003c\/li\u003e\n\u003cli\u003eDial indicator included; accessories included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-use precision measurement tool for internal bore diameters from 2 to 6 inches.

Handle the anvil tips carefully to avoid damage that would affect accuracy. Calibration should be verified periodically per the facility quality plan or applicable metrology standards. Store the gage in its case when not in use to protect the dial indicator and anvil contact points.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 2 to 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Anvils\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicator Included\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\u003ePackage Dimensions\u003c\/strong\u003e: 16.38 inches (L) x 7.32 inches (W) x 2.44 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: 511-753-20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51557797200178,"sku":"511-753-20","price":549.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfb03bf1b590d2da399934bb5d1c4b36.jpg?v=1786395525","url":"https:\/\/voomisupply.com\/products\/mitutoyo-511-753-20-dial-bore-gage-2-to-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
