It features a 6-inch maximum measurement range with six interchangeable rotating rods, allowing the technician to span a wide variety of bore and slot depths without switching instruments. Graduation is 0.0001 inches with an accuracy of 0.0002 inches, making it suitable for close-tolerance inspection work. A ratchet stop thimble provides consistent measuring pressure to eliminate operator-to-operator variation. The instrument ships NIST certified with a short-form certificate of calibration included.\u003c\/p\u003e\n\u003cp\u003eThis depth micrometer is used on the shop floor and in inspection rooms for measuring the depth of slots, holes, counterbores, and recesses in metal, plastic, and composite workpieces. The 4-inch base length provides stable seating across wide surfaces. The digital counter feature aids readability during repeated measurements. Machinists, tool-and-die makers, and quality technicians are the typical end users. It is equally applicable in job-shop and production environments where traceable calibration records are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-inch measurement range with 6 interchangeable rotating rods for versatile depth measurement\u003c\/li\u003e\n  \u003cli\u003e0.0001-inch graduation with 0.0002-inch accuracy for high-precision inspection\u003c\/li\u003e\n  \u003cli\u003eRatchet stop thimble ensures consistent, repeatable measuring force\u003c\/li\u003e\n  \u003cli\u003e4-inch base length for stable contact across wide workpiece surfaces\u003c\/li\u003e\n  \u003cli\u003eHardened steel measuring faces for wear resistance in production use\u003c\/li\u003e\n  \u003cli\u003eNIST-certified calibration with short-form certificate of calibration included\u003c\/li\u003e\n  \u003cli\u003eDigital counter for easy reading during repetitive measurement tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose mechanical depth micrometer suitable for standard depth measurement applications in machining, toolroom, and quality-assurance settings where a 6-inch range and NIST-traceable calibration are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis instrument should be handled and stored in its included protective case to preserve calibration integrity. Before use, verify the zero setting with all rods removed and the base seated flat on a reference surface. Avoid dropping or impacting the micrometer, as shock can alter calibration. Periodic recalibration by a qualified metrology technician is recommended to maintain NIST traceability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement Range\u003c\/strong\u003e: 6 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 Rods\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Type\u003c\/strong\u003e: Rotating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Diameter\u003c\/strong\u003e: 0.176 inches (4.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet Stop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Hardened Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibration Standard\u003c\/strong\u003e: NIST Certified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Case, Short Form Certificate of Calibration\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.85 inches (L) x 5.32 inches (W) x 1.82 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.39 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: CMS160809100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51695084732722,"sku":"CMS160809100","price":220.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/468e3fe3d7105c39defb3a10377f54e9.jpg?v=1788331187","url":"https:\/\/voomisupply.com\/products\/spi-cms160809100-mechanical-depth-micrometer-6-in-6-rods","provider":"Voomi Supply","version":"1.0","type":"link"}
