It delivers a total measurement range of 0.25 inches with a graduation of 0.001 inches per division, allowing repeatable readings at tight tolerances. The balanced 0-50-0 dial face with white background improves readability in shop environments. The stem diameter is 0.375 inches, conforming to standard indicator holder and magnetic base collets. This tool is used by machinists, tool-and-die technicians, and quality-control inspectors who need reliable, cost-effective drop indicator performance.\u003c\/p\u003e\n\u003cp\u003eThe CMS160726050 is suited for use on surface plates, mill setups, lathe compound slides, and fixture runout checks. Its 0.1 inch per revolution travel and universal positioning stem make it a practical choice for both bench inspection and in-machine measurement. The counter pointer aids in tracking cumulative travel when the indicator passes through zero. It meets US Federal Specifications and carries an AGD Group 1 classification, placing it within the standardized size and accuracy class for general-purpose dial indicators in production and quality environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25 inch total measurement range with 0.001 inch graduations for fine-resolution readings\u003c\/li\u003e\n  \u003cli\u003e0-50-0 balanced dial reading with white dial face for clear visibility\u003c\/li\u003e\n  \u003cli\u003e0.1 inch per revolution travel for consistent spindle feedback\u003c\/li\u003e\n  \u003cli\u003e0.375 inch stem diameter fits standard AGD-compatible holders and magnetic bases\u003c\/li\u003e\n  \u003cli\u003eCounter pointer tracks full revolutions to prevent misreading cumulative travel\u003c\/li\u003e\n  \u003cli\u003eMeets US Federal Specifications; classified as AGD Group 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an AGD Group 1 dial drop indicator compatible with standard 0.375 inch stem-diameter indicator holders, magnetic bases, and universal positioning arms used in general machining and inspection setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting and setup of dial indicators should be performed by qualified machinists or metrologists familiar with indicator holder torque and contact point selection. Always secure the stem firmly in the holder before taking measurements to prevent spindle deflection errors. Do not force the spindle beyond its rated travel range, as overtravel can damage the gear train. Follow shop calibration schedules and handle the instrument carefully to avoid shock loads that affect accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-50-0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange Per Revolution\u003c\/strong\u003e: 0.1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 1.61 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 0.375 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-48 \/ M2.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRevolution Counter\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAGD Group\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: US Federal Specifications\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6 inches L x 3 inches W x 1 inch H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111630\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: CMS160726050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51689762783538,"sku":"CMS160726050","price":94.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec8af344534483b42408d0481de4a18c.jpg?v=1788264030","url":"https:\/\/voomisupply.com\/products\/spi-cms160726050-dial-drop-indicator-0-25-in-range","provider":"Voomi Supply","version":"1.0","type":"link"}
