It covers a measurement range of 0.2250 to 0.2750 inches, with a graduation of 0.0001 inches and an accuracy of 0.0002 inches. Three-point solid carbide contact anvils are self-aligning and self-centering, which reduces operator error and produces consistent readings across multiple measurements. A ratchet stop thimble controls measuring force, preventing over-tightening and protecting the workpiece surface. This instrument is suited for quality control, precision machining, and inspection work performed by machinists, toolmakers, and metrology technicians.\u003c\/p\u003e\n\u003cp\u003eThe 10-703-7 is used in precision manufacturing and inspection environments where small-bore dimensional verification is required. Typical applications include checking drilled, reamed, or bored holes in metal components during production or incoming inspection. The 0.7800-inch gage depth and 0.2750-inch setting ring diameter define the reach and calibration reference for this tool. It is appropriate for both shop-floor and lab use where tolerances are tight and manual measurement is specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range: 0.2250 to 0.2750 inches for small-bore applications\u003c\/li\u003e\n  \u003cli\u003eGraduation of 0.0001 inches supports high-resolution dimensional checks\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0002 inches for reliable, repeatable results\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring anvils resist wear on hardened and abrasive workpieces\u003c\/li\u003e\n  \u003cli\u003eSelf-aligning and self-centering three-point contact for consistent bore registration\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble controls applied force and prevents measurement error from over-tightening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standalone mechanical hole micrometer for precision bore measurement in the 0.2250 to 0.2750 inch range.

Before use, verify the tool is zeroed or calibrated against a known reference standard appropriate to the measurement range. Keep the measuring anvils clean and free of debris to maintain accuracy. Store in a protective case away from temperature extremes and direct contact with other tools to prevent damage to the carbide anvil surfaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicrometer Type\u003c\/strong\u003e: Hole (Inside)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.2250 to 0.2750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\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\u003eNumber of Contact Points\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 0.7800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting Ring Diameter\u003c\/strong\u003e: 0.2750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Extension Rods\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Setting Rings Included\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDigital Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111601\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: 10-703-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51715044442418,"sku":"10-703-7","price":338.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6279eeaf7d0f8333e0ed893fc57f1e17.jpg?v=1788509213","url":"https:\/\/voomisupply.com\/products\/spi-10-703-7-hole-micrometer-0-2250-0-2750-inch-range","provider":"Voomi Supply","version":"1.0","type":"link"}
