It covers a measurement range of 0 to 1 inch with a dial graduation of 0.0005 inches, allowing technicians to detect very small deviations in surface position, runout, or alignment. The indicator features a 2.25-inch white dial with a 0-50 reading scale, a jeweled bearing mechanism for consistent accuracy, and a stainless steel stem with a diameter of 0.375 inches. A no-glare satin finish and unbreakable crystal face reduce visual fatigue during extended use. The unit ships with both a lug back and a flat back included.\u003c\/p\u003e\n\u003cp\u003eThis indicator is suited for use by machinists, tool and die makers, metrologists, and maintenance technicians performing setup, inspection, or in-process gauging. Typical applications include spindle runout checks, part flatness verification, fixture alignment, and surface comparator work on mills, lathes, surface plates, and inspection fixtures. The revolution counter tracks full spindle revolutions across the 1-inch total travel, making it straightforward to read cumulative displacement without losing count during longer traverses.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0005-inch graduation provides fine resolution for precision measurement tasks\u003c\/li\u003e\n  \u003cli\u003eJeweled bearing mechanism supports smooth, repeatable stem travel\u003c\/li\u003e\n  \u003cli\u003eStainless steel stem resists corrosion and wear in shop environments\u003c\/li\u003e\n  \u003cli\u003eRevolution counter tracks cumulative travel over the full 1-inch range\u003c\/li\u003e\n  \u003cli\u003eNo-glare satin finish and unbreakable crystal reduce reading errors and face damage\u003c\/li\u003e\n  \u003cli\u003eIncludes both lug back and flat back mounting options for flexible setup\u003c\/li\u003e\n  \u003cli\u003e2.25-inch dial diameter with white face for clear readability at arm length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard AGD Group 2 dial drop indicator compatible with indicator holders, magnetic base arms, and surface gauge stems that accept a 0.375-inch stem diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDial drop indicators are installed by licensed machinists and quality technicians using magnetic bases, indicator holders, or snug-fit collet-style arms. Before mounting, ensure the workpiece and fixture are secure and the machine spindle or surface is stationary. Clamp the stem with enough grip to hold position without crushing the stainless steel stem. Do not exceed the rated 1-inch travel range, as over-travel can damage the jeweled bearing and rack mechanism.\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 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRange Per Revolution\u003c\/strong\u003e: 0.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2.25 inches (57.15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Diameter\u003c\/strong\u003e: 0.375 inches (9.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Length\u003c\/strong\u003e: 0.7188 inches (18.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Lug Back (Flat Back included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBearing Type\u003c\/strong\u003e: Jeweled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRevolution Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrystal\u003c\/strong\u003e: Unbreakable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: No-Glare Satin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAGD Group\u003c\/strong\u003e: 2\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: 0.688 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: 53304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541373223218,"sku":"53304","price":293.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af62b7c60be54fcef42f0c0ec96f7fa4.jpg?v=1785873935","url":"https:\/\/voomisupply.com\/products\/starrett-53304-dial-drop-indicator-0-1-in-0-0005-grad","provider":"Voomi Supply","version":"1.0","type":"link"}
