It features a 0.2 inch total measurement range with 0.001 inch graduation and 0.001 inch accuracy, making it suitable for close-tolerance work on the shop floor or in a quality control environment. The 40 mm dial face provides clear readability, and a built-in revolution counter tracks full spindle cycles. A rotating bezel and limit markers allow technicians to set reference positions quickly. Machinists, tool and die makers, and quality inspectors are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThis indicator is used in setups where a standard dial indicator cannot be positioned vertically — the drop-style plunger allows measurement access in restricted or angled orientations. Typical applications include surface plate inspection, fixture setup, runout checks on lathes and mills, and comparator-stand measurements. The ANSI\/AGD standard compliance and AGD Group 0 classification confirm it fits standard AGD-compatible indicator holders and magnetic base accessories common in machine shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.2 inch total measurement range with 0.001 inch graduation and 0.001 inch accuracy\u003c\/li\u003e\n  \u003cli\u003e40 mm dial face with 0-50 dial reading scale for easy reading in both directions\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch range per revolution keeps tracking simple during multi-pass setups\u003c\/li\u003e\n  \u003cli\u003eBuilt-in revolution counter prevents misreading on multi-turn measurements\u003c\/li\u003e\n  \u003cli\u003eRotating bezel and limit markers for fast reference-point setting\u003c\/li\u003e\n  \u003cli\u003ePlunger style with No. 4-48 thread size for compatibility with standard AGD accessories\u003c\/li\u003e\n  \u003cli\u003eANSI\/AGD compliant, AGD Group 0 classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard AGD-compatible indicator holders, magnetic bases, and comparator stands that accept AGD Group 0 plunger-style dial indicators with a No. 4-48 stem thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed metrologist, machinist, or quality technician typically mounts and calibrates this indicator. Secure the stem in a rigid AGD-compatible holder or magnetic base before taking measurements — any flex in the mounting will reduce accuracy. Avoid side-loading the plunger, as this can introduce error and cause premature wear on the spindle. Handle the instrument carefully; dropping or striking the dial face can affect calibration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange per Revolution\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndicator Style\u003c\/strong\u003e: Plunger\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: No. 4-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRevolution Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Limit Markers, Rotating Bezel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\/AGD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAGD Group\u003c\/strong\u003e: 0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1166A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51561915679026,"sku":"1166A","price":195.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ca7cc19d414ef287603733518f67daa1.jpg?v=1786469892","url":"https:\/\/voomisupply.com\/products\/mitutoyo-1166a-dial-drop-indicator-0-2-in-0-001-in","provider":"Voomi Supply","version":"1.0","type":"link"}
