It covers a measuring range of 3.5 to 4 inches with a resolution of 0.0001 inches and accuracy up to 0.0002 inches. The gage features a pistol-grip handle for single-handed operation and supports both right- and left-hand viewing, making it practical for technicians measuring in tight or awkward bore orientations. The 3-point contact heads are constructed from solid carbide for long-term durability under repeated use. The unit ships with an indicator, CR2032 battery, and accessories, all housed in a fitted carrying case.\u003c\/p\u003e\n\u003cp\u003eThis bore gage is suited for precision measurement tasks in manufacturing, engine rebuilding, quality control, and maintenance environments where consistent internal diameter readings are required. The pistol-grip form factor and single-handed operation make it practical for production-floor use as well as bench-top inspection. The 4.48-inch gage depth allows measurement access in deeper bores within the 3.5 to 4 inch range. Machinists, metrologists, and toolroom technicians are the primary users of this instrument.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-point solid carbide contact heads for durability and consistent seating in the bore\u003c\/li\u003e\n  \u003cli\u003eMeasuring range of 3.5 to 4 inches with 0.0001 inch resolution\u003c\/li\u003e\n  \u003cli\u003ePistol-grip handle enables single-handed operation\u003c\/li\u003e\n  \u003cli\u003eSupports right-hand and left-hand viewing for flexible positioning\u003c\/li\u003e\n  \u003cli\u003eAutomatic shut-off to preserve battery life\u003c\/li\u003e\n  \u003cli\u003eFurnished in a fitted case with indicator and battery included\u003c\/li\u003e\n  \u003cli\u003e2-year manufacturer warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use as a standalone precision bore measurement instrument for internal diameters from 3.5 to 4 inches. The included indicator integrates directly with the gage body; no additional indicator purchase is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument requires no installation in a fixed system but should be handled and stored in its fitted case to protect the carbide contact heads and indicator. Calibrate against a known ring gage or master setting ring before use, following the manufacturer calibration procedure. Avoid dropping or subjecting the gage to impact, as this can shift calibration or damage the 3-point head assembly. Battery replacement uses a CR2032 cell; the automatic shut-off feature extends battery service life between replacements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Range\u003c\/strong\u003e: 3.5 to 4 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: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 4.48 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Head Material\u003c\/strong\u003e: Solid Carbide (3-Point Heads)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePistol Grip\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndicator Included\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery Type\u003c\/strong\u003e: CR2032 (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 14.18 inches length x 8.27 inches width x 5.91 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.5 pounds\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: CMS160712052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51721309651250,"sku":"CMS160712052","price":1101.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48f7e4116b690c5c9e46994b3cfdf111.jpg?v=1788576206","url":"https:\/\/voomisupply.com\/products\/spi-cms160712052-electronic-bore-gage-3-5-to-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
