It covers a measuring range of 0.275 to 0.5 inches with a resolution of 0.0001 inches and an accuracy of 0.0003 inches (0.008 mm). The gage uses a 3-point solid carbide contact head for consistent, repeatable readings and includes a digital indicator with 360-degree screen rotation for right- and left-hand viewing. It is intended for use by machinists, engine technicians, and precision measurement professionals who require reliable bore data in tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis gage is suited for small-bore measurement tasks in automotive engine rebuilding, precision machining shops, and mechanical repair facilities. The pistol grip housing supports single-handed operation, and the gage depth of 2 inches allows measurement in moderately deep bores. Inch-to-metric conversion is built in, making it practical for work environments that use both measurement systems. The unit ships complete in a fitted protective case with all accessories included, ready for immediate use on the bench or in the field.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-point solid carbide contact head for durable, repeatable internal diameter measurement\u003c\/li\u003e\n  \u003cli\u003e360-degree screen rotation supports right-hand and left-hand viewing angles\u003c\/li\u003e\n  \u003cli\u003eSingle-handed pistol grip operation for stability during measurement\u003c\/li\u003e\n  \u003cli\u003eBuilt-in inch\/metric conversion for dual-system work environments\u003c\/li\u003e\n  \u003cli\u003eAutomatic shut-off extends battery life between uses\u003c\/li\u003e\n  \u003cli\u003eFurnished in a fitted protective case with accessories included\u003c\/li\u003e\n  \u003cli\u003e2-year warranty on the instrument\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision measurement tool for small internal bores in the 0.275 to 0.5 inch range, suitable for use in machine shop, automotive, and general mechanical service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument is used by machinists and mechanical technicians and does not require installation in a system. Before use, zero the gage against a certified setting ring or master gage to ensure measurement accuracy. Handle the carbide contact heads carefully to avoid chipping, and store the unit in its fitted case when not in use. Battery replacement uses a CR2032 cell; consult the manufacturer documentation for battery access procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Range (Minimum)\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Range (Maximum)\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0003 inches (0.008 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Head Material\u003c\/strong\u003e: Solid Carbide (3-Point)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: CR2032 (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 13 inches (L) x 8.67 inches (W) x 4.06 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 2 years\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111600\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CMS160712051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51723360370994,"sku":"CMS160712051","price":1559.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12b21761a0fb82ba05cc255f4285f2a2.jpg?v=1788603886","url":"https:\/\/voomisupply.com\/products\/spi-cms160712051-electronic-bore-gage-0-275-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
