It measures holes up to 0.225 inches with a graduation of 0.0001 inches and an accuracy of 0.0002 inches, making it suitable for close-tolerance work where reliable repeatability is required. The ratchet stop thimble controls measuring pressure to promote consistent readings across multiple measurements. Solid carbide measuring anvils provide wear resistance for extended service life in production environments. This instrument is installed and used by machinists, tool and die makers, and quality control technicians.\u003c\/p\u003e\n\u003cp\u003eThe SPI 10-702-9 is suited for measuring small-diameter bores, holes, and internal features in precision machined components. Its self-aligning and self-centering three-contact-point design simplifies positioning inside the bore, reducing operator technique variation. A gage depth of 0.78 inches allows access to typical through-holes and counterbores encountered in toolroom and light manufacturing work. The setting ring diameter matches the maximum measurement range at 0.225 inches for accurate calibration of the instrument before use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range up to 0.225 inches with 0.0001-inch graduation\u003c\/li\u003e\n  \u003cli\u003eAccuracy of 0.0002 inches for close-tolerance inspection\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble for controlled, repeatable measuring pressure\u003c\/li\u003e\n  \u003cli\u003eSolid carbide measuring anvils resist wear in production use\u003c\/li\u003e\n  \u003cli\u003eSelf-aligning and self-centering three-contact-point design\u003c\/li\u003e\n  \u003cli\u003eGage depth of 0.78 inches for access to standard bore depths\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision measuring instrument for use in toolroom, machining, and quality inspection environments requiring small internal bore measurement up to 0.225 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument is used by machinists and quality technicians and requires no installation in the traditional sense. Before use, zero and verify the micrometer against its setting ring or a calibrated standard in accordance with your facility's metrology procedures. Handle carbide anvils carefully to avoid chipping from impact or improper storage. Store in a protective case away from temperature extremes to maintain calibration integrity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMicrometer Type\u003c\/strong\u003e: Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 0.225 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\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\u003eNumber of Contact Points\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 0.78 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSetting Ring Diameter\u003c\/strong\u003e: 0.225 inches\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: 0.65 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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10-702-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51699050381618,"sku":"10-702-9","price":340.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3c60a70a75ebd9ee9b0ae7b1e604288.jpg?v=1788371698","url":"https:\/\/voomisupply.com\/products\/spi-10-702-9-mechanical-hole-micrometer-0-225-inch-range","provider":"Voomi Supply","version":"1.0","type":"link"}
