It covers a measurement range of 0 to 0.1 inches with a graduation of 0.001 inches per division, giving technicians reliable, repeatable readings on close-tolerance work. The balanced and tapered hands read against a 0-20-0 white eggshell dial face with a no-glare, unbreakable crystal bezel. A built-in revolution counter tracks full-stroke travel, and the frictionally adjustable bezel allows quick zero-setting without tools. The jeweled bearing construction reduces friction and extends service life in high-cycle inspection routines.\u003c\/p\u003e\n\u003cp\u003eThis indicator is suited for use on surface plates, magnetic bases, transfer stands, and fixture-mounted holders in machine shops, fabrication facilities, and precision maintenance environments. The lug back mount is a standard attachment style compatible with a wide range of indicator holders and transfer gauging setups. Trades that commonly use this tool include machinists, toolmakers, millwrights, and mechanical maintenance technicians performing alignment, runout, or flatness checks on rotating or stationary parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 0.1 inch measurement range with 0.001 inch graduations for close-tolerance inspection\u003c\/li\u003e\n  \u003cli\u003e0-20-0 balanced dial reading with revolution counter for full-stroke travel tracking\u003c\/li\u003e\n  \u003cli\u003eJeweled bearing construction for reduced friction and extended service life\u003c\/li\u003e\n  \u003cli\u003eLug back mount for compatibility with standard indicator holders and transfer stands\u003c\/li\u003e\n  \u003cli\u003eFrictionally adjustable bezel for fast, tool-free zero-setting\u003c\/li\u003e\n  \u003cli\u003eNo-glare, unbreakable crystal over white eggshell dial face for clear readings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision measuring instrument for use with standard lug-back indicator holders, magnetic bases, and surface-plate transfer fixtures commonly found in machine shop and inspection environments.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting is performed by machinists or mechanical technicians using a standard lug-back clamp or holder. Ensure the stem is seated squarely and the indicator spindle contacts the workpiece perpendicular to the measured surface to avoid cosine error. Do not overtighten the lug clamp, as this can distort the case and affect calibration. Zero the bezel after mounting and before taking measurements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 0.1 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: 0-20-0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange Per Revolution\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 1.25 inches (31.75 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead\/Holder Diameter\u003c\/strong\u003e: 1-17\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 0.2185 inches (5.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 0.5938 inches (15.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 51.00 mm (approximately 2.0 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Lug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Jeweled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRevolution Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: English\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.438 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: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 55893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538274615602,"sku":"55893","price":394.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77f0c8cbea35598b32feb84af58a12f1.jpg?v=1785821415","url":"https:\/\/voomisupply.com\/products\/starrett-55893-dial-drop-indicator-0-001-in-graduation","provider":"Voomi Supply","version":"1.0","type":"link"}
