It features a 3-point contact system with solid carbide measuring anvils that self-align and self-center within the bore, eliminating the need for manual rocking to find true diameter. Graduation is 0.0002 inches with a rated accuracy of 0.0002 inches. A ratchet stop thimble provides consistent measuring force for repeatable readings. This tool is well suited to machine shops, maintenance facilities, and precision manufacturing environments where accurate bore gauging is required.\u003c\/p\u003e\u003cp\u003eThe 10-733-4 is used for measuring internal diameters in the 1.200 to 1.400 inch range, typical in applications such as engine bore inspection, bearing housing measurement, and precision bore qualification in both production and maintenance settings. The carbide anvil faces provide durability against wear in repetitive measurement cycles. The instrument reaches a gage depth of 3.150 inches, making it useful for measuring bores that extend beyond the surface. Machinists, toolmakers, and quality control technicians are the primary users of this instrument.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range: 1.200 to 1.400 inches\u003c\/li\u003e\n\u003cli\u003eGraduation of 0.0002 inches with accuracy rated at 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e3-point contact design provides self-aligning and self-centering measurement\u003c\/li\u003e\n\u003cli\u003eSolid carbide measuring anvils for extended wear resistance\u003c\/li\u003e\n\u003cli\u003eRatchet stop thimble ensures consistent, repeatable measuring force\u003c\/li\u003e\n\u003cli\u003eGage depth of 3.150 inches for access to deeper bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-use hole micrometer for internal bore measurement applications requiring a 1.200 to 1.400 inch range with 3-point carbide contact.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis instrument is a handheld precision measuring tool and does not require installation. Prior to use, verify calibration against a known standard and ensure the measuring faces are clean and free of debris. Store in the provided case when not in use to protect the carbide anvils and maintain calibration integrity. Handle with care to avoid dropping, which can affect accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrometer Type\u003c\/strong\u003e: Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 1.200 to 1.400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.0002 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: 3.150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extension Rod Length\u003c\/strong\u003e: 6.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetting Ring Diameter\u003c\/strong\u003e: 1.400 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: 1.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 10-733-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51722315432242,"sku":"10-733-4","price":339.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74751bc294e2a53f7fb9e19961c048d4.jpg?v=1788589198","url":"https:\/\/voomisupply.com\/products\/spi-10-733-4-mechanical-hole-micrometer-1-200-1-400-in","provider":"Voomi Supply","version":"1.0","type":"link"}
