It delivers a 1-inch total measurement range with a graduation of 0.001 inches per division, allowing technicians to detect surface variation, runout, and alignment deviation with reliable accuracy. The indicator features a 2-1\/4 inch white dial face with a 0-100 reading scale and a revolution counter that tracks full rotations across the measurement range. Each revolution covers 0.1 inches of travel. The solid steel housing provides durability in shop environments, and a carbide contact point resists wear during repeated use. Machinists, quality inspectors, and tool-and-die technicians are the primary installers and users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThis dial drop indicator is suited for use in machine shops, fabrication facilities, and inspection departments where consistent linear measurement is required. It mounts via a lug back, making it compatible with standard indicator holders, magnetic bases, and surface plate setups. Tolerance markers are included, allowing quick pass\/fail inspection without additional calculation. It is well suited to checking part flatness, spindle runout, fixture alignment, and workpiece positioning on manual or CNC machine tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch total measurement range with 0.001-inch graduation for fine linear measurement\u003c\/li\u003e\n  \u003cli\u003eRevolution counter tracks full rotations across the full range of travel\u003c\/li\u003e\n  \u003cli\u003e0.1 inches of travel per revolution for easy reading across multiple rotations\u003c\/li\u003e\n  \u003cli\u003eCarbide contact point for extended wear life in high-cycle inspection use\u003c\/li\u003e\n  \u003cli\u003eSolid steel housing provides durability in production and shop environments\u003c\/li\u003e\n  \u003cli\u003eLug back mount compatible with standard indicator holders and magnetic bases\u003c\/li\u003e\n  \u003cli\u003eIncludes tolerance markers for rapid pass\/fail visual inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard lug-back indicator holders, magnetic bases, and surface plate fixtures commonly used in machine shop and inspection environments.

Ensure the indicator stem is clamped securely and aligned perpendicular to the measured surface to prevent cosine error. Do not force the spindle beyond its rated travel range, as this may damage the internal gear mechanism. Zero the dial face before taking measurements and verify the contact point is fully seated against the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 1 inch\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: 0-100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 2-1\/4 inches\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\u003eStem Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Lug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRevolution Counter\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Point\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Solid Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: English (inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: FOWLER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 52-520-110-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FOWLER","offers":[{"title":"Default Title","offer_id":67917852836146,"sku":"52-520-110-2","price":91.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11a1c8eba9ecf5125b637816d9be0937_cf81ddf3-835b-418d-aadb-a925dcd8481d.jpg?v=1791265756","url":"https:\/\/voomisupply.com\/products\/fowler-52-520-110-2-dial-drop-indicator-1-in-0-001-grad","provider":"Voomi Supply","version":"1.0","type":"link"}
