It delivers a resolution of 0.00005 inches (0.001 mm) and accuracy down to 0.00012 inches (0.002 mm in narrow range). The unit features an ultra-compact built-in sensor that allows measurement in deep holes up to a gage depth of 6 inches (152.4 mm). Data output capability makes it compatible with SPC data collection workflows. The 511-521 is suited for quality control technicians, machinists, and precision measurement professionals who require repeatable bore measurement in production or inspection environments.\u003c\/p\u003e\n\u003cp\u003eThis bore gage is used in machine shops, manufacturing facilities, and inspection departments for measuring internal diameters of bores, cylinders, and housings where tight tolerances must be verified. Its GO\/NO-GO judgment function streamlines pass\/fail inspection on production lines. The compact sensor design allows access to deep or narrow bore profiles that standard dial-type bore gages cannot reach. The 511-521 is appropriate for both inch and metric applications and supports inch\/mm conversion directly on the instrument.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasuring range of 1.8 to 4 inches (45 to 100 mm) with 0.00005-inch resolution\u003c\/li\u003e\n  \u003cli\u003eUltra-compact built-in sensor reaches deep holes up to 6 inches (152.4 mm) gage depth\u003c\/li\u003e\n  \u003cli\u003eGO\/NO-GO judgment with upper and lower tolerance limit setting\u003c\/li\u003e\n  \u003cli\u003eData output port for SPC or digital readout integration\u003c\/li\u003e\n  \u003cli\u003eIP53 water resistance rating for use in light coolant environments\u003c\/li\u003e\n  \u003cli\u003eInch\/mm conversion, zero\/ABS setting, and low battery indicator included\u003c\/li\u003e\n  \u003cli\u003ePowered by 2 SR44 silver oxide batteries, included with the gage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision measurement tool for use with standard bore gage anvil sets. The 511-521 ships with 14 anvils and a 20-piece total kit configuration. Verify anvil range coverage against the specific bore diameters to be measured before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSetup and calibration should be performed by a qualified metrologist or trained quality technician familiar with bore gage procedures. Set the origin using a certified ring gage or master setting fixture before taking measurements. Ensure the gage is thermally stabilized to ambient temperature before use to minimize thermal expansion error. Follow the manufacturer calibration interval recommendations and handle the contact anvils carefully to avoid damage to the precision measuring surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Range (Inch)\u003c\/strong\u003e: 1.8 to 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Range (mm)\u003c\/strong\u003e: 45 to 100 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution (Inch)\u003c\/strong\u003e: 0.00005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution (mm)\u003c\/strong\u003e: 0.001 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy (Narrow Range)\u003c\/strong\u003e: 0.00012 inches (0.002 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy (Wide Range)\u003c\/strong\u003e: 0.003 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 6 inches (152.4 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWater Resistance Rating\u003c\/strong\u003e: IP53\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Anvils\u003c\/strong\u003e: 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Type\u003c\/strong\u003e: SR44 Silver Oxide (qty 2, included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 pounds\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: 511-521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559441760562,"sku":"511-521","price":1507.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c8b50a4a8d03506967af194ad8f467f.jpg?v=1786432564","url":"https:\/\/voomisupply.com\/products\/mitutoyo-511-521-electronic-bore-gage-1-8-to-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
