It features a carbide measuring face and a ratchet-stop thimble for repeatable seating force, delivering an accuracy of 0.0002 inches. The set uses an extension rod configuration with a maximum extension rod length of 6 inches and a gage depth of 90 mm, allowing measurements close to the bottom of blind holes. A 3V CR2032 lithium battery is included, and the instrument supports data output for integration with SPC or digital recording systems. Licensed metrology technicians, toolroom machinists, and quality control personnel are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis inside micrometer set is suited for precision inspection work in manufacturing, toolroom, and quality assurance environments. The extension rod design accommodates a variety of bore depths and diameters in the 2 to 4 inch range. Measuring contact points are engineered to reach near the bottom of blind holes, making the set applicable in engine rebuilding, hydraulic component inspection, and close-tolerance machining verification. The set is factory calibrated and conforms to ASME B89.1.13 standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasurement range of 2 to 4 inches with 0.0002 inch accuracy\u003c\/li\u003e\n  \u003cli\u003eCarbide measuring faces for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eRatchet-stop thimble ensures consistent measuring pressure\u003c\/li\u003e\n  \u003cli\u003eExtension rod type with maximum rod length of 6 inches for deep bore access\u003c\/li\u003e\n  \u003cli\u003eMeasuring contact points designed to reach near the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eData output capability for SPC and digital recording integration\u003c\/li\u003e\n  \u003cli\u003eFactory calibrated; conforms to ASME B89.1.13\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision measurement tool for internal bore inspection applications requiring a 2 to 4 inch range with extension rod capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSetup and zeroing should be performed by a qualified metrology technician or toolroom machinist following the manufacturer documentation included with the set. Store the instrument in its protective case when not in use to prevent damage to the carbide contact faces. Do not exceed the rated measurement range or apply lateral force to the extension rod during measurement, as this can introduce error or damage the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Type\u003c\/strong\u003e: Extension\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extension Rod Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGage Depth\u003c\/strong\u003e: 90 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: 3V CR2032 Lithium (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1.13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7 inches L x 3.4 inches W x 0.97 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.24 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: CMS220519063\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51712514130226,"sku":"CMS220519063","price":3351.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2da3c87667c8a895d3cd449d3590795d_3feb7cbe-e6c8-4c9a-b04d-64198dedf38e.jpg?v=1788486370","url":"https:\/\/voomisupply.com\/products\/spi-cms220519063-electronic-inside-micrometer-set","provider":"Voomi Supply","version":"1.0","type":"link"}
