The kit centers on a dial test indicator with a 1-3\/8 inch (34.93 mm) dial diameter, a 0-40-0 dial reading, and a dial graduation of 0.01 mm, making it well suited for close-tolerance runout checks, surface alignment, and fixture setups. The yellow dial face provides clear contrast for fast readings. The carbide contact point and full accessory set allow the indicator to be mounted and repositioned quickly across a range of workholding and machine tool configurations. Licensed machinists, tool and die makers, and precision mechanics are the primary users.\u003c\/p\u003e\u003cp\u003eThis kit is built for use in manual machining, CNC setup verification, and quality control environments where repeatable, fine-increment readings are required. The contact point length is 20.64 mm with a 2 mm ball diameter (0.078 inches), suited for reaching into tight bores or along flat surfaces. The included accessories allow the indicator to be adapted to dovetail mounts, swivel posts, and tool posts without sourcing additional hardware.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDial graduation of 0.01 mm for fine-increment measurement\u003c\/li\u003e\n\u003cli\u003e1-3\/8 inch (34.93 mm) dial diameter with high-contrast yellow face and 0-40-0 reading\u003c\/li\u003e\n\u003cli\u003eCarbide contact point for extended wear resistance\u003c\/li\u003e\n\u003cli\u003e2 mm ball diameter contact with 20.64 mm contact point length\u003c\/li\u003e\n\u003cli\u003e7-piece kit includes carbide contact, case, dial test indicator, dovetail body clamp, snug and rod unit, swivel post snug with dovetail indicator clamp, and tool post holder\u003c\/li\u003e\n\u003cli\u003eDovetail-compatible mounting system for broad workholding adaptability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-use dial test indicator kit for standard dovetail-mount indicator systems common in toolroom and machine shop environments.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or toolroom technicians familiar with indicator mounting and machine setup procedures. Secure the indicator in the appropriate clamp or holder before zeroing; ensure the contact point is perpendicular or at the correct approach angle to the measured surface to avoid cosine error. Power down any CNC spindle or moving axis before positioning the indicator. Do not overtighten dovetail clamp screws, as this can distort the indicator body and affect calibration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Diameter\u003c\/strong\u003e: 1-3\/8 inches (34.93 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Reading\u003c\/strong\u003e: 0-40-0\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Graduation\u003c\/strong\u003e: 0.01 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial Color\u003c\/strong\u003e: Yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Point Length\u003c\/strong\u003e: 20.64 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBall Diameter\u003c\/strong\u003e: 2 mm (0.078 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Type\u003c\/strong\u003e: Dial Test Indicator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Carbide Contact, Case, Dial Test Indicator, Dovetail Body Clamp, Snug and Rod Unit, Swivel Post Snug With Dovetail Indicator Clamp, Tool Post Holder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 64221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542752919858,"sku":"64221","price":550.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7925d968f9668ec650f56249e2689da9.jpg?v=1785906269","url":"https:\/\/voomisupply.com\/products\/starrett-64221-dial-test-indicator-kit-7-piece","provider":"Voomi Supply","version":"1.0","type":"link"}
