Built from cast iron with ground and graduated main vials, this level delivers a graduation sensitivity of 0.0005 inches per 10 inches, making it well-suited for precision machinery leveling, surface plate setup, and equipment alignment in machine shops and industrial environments. At 15 inches in length and 8.1 pounds, it provides a stable, repeatable reading base. Licensed machinists, millwrights, and precision tool-and-die technicians are the primary users of this instrument.\u003c\/p\u003e\n\u003cp\u003eThe STARRETT 66932 is used in industrial and manufacturing settings where surface flatness and machine alignment must be verified to tight tolerances. Typical applications include leveling machine tool beds, aligning rotary equipment, setting surface plates, and verifying level on precision grinding and milling machines. With two horizontal vials and a ground base, the level provides both primary and cross-check readings in a single setup. It is suited for shop floor and metrology room use in both OEM production and maintenance-repair-overhaul environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGraduation sensitivity of 0.0005 inches per 10 inches for tight-tolerance alignment work\u003c\/li\u003e\n  \u003cli\u003eCast iron construction for thermal stability and resistance to shop-floor wear\u003c\/li\u003e\n  \u003cli\u003eGround and graduated main vials for repeatable, accurate readings\u003c\/li\u003e\n  \u003cli\u003eTwo horizontal vials allow simultaneous primary and cross-axis level checks\u003c\/li\u003e\n  \u003cli\u003e15-inch base length provides a stable reference span across machine surfaces\u003c\/li\u003e\n  \u003cli\u003eBase flatness of 1\/64 inch ensures reliable contact on precision surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style master precision level for use on machine tool beds, surface plates, and precision industrial equipment requiring sub-thousandth-inch alignment verification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of precision levels should be performed by qualified machinists or millwrights familiar with machine tool alignment procedures. Always de-energize and lock out equipment before placing the level on any machine surface. Clean the base and work surface thoroughly before use to prevent debris from affecting readings. Avoid placing the level near strong magnetic fields or heat sources that could affect vial fluid and introduce reading error.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLevel Type\u003c\/strong\u003e: Master Precision\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduation Sensitivity Per 10 Inches\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Flatness\u003c\/strong\u003e: 1\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Horizontal Vials\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVial Features\u003c\/strong\u003e: Ground and Graduated Main Vials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8.1 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: 66932\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542749544754,"sku":"66932","price":1488.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7bd3368b061e550fcf7f782a944875fb.jpg?v=1785906137","url":"https:\/\/voomisupply.com\/products\/starrett-66932-master-precision-level-15-in-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
