The tool features 5 right-hand flutes, a 0.343-inch cutting diameter, and a 1.107-inch length of cut, making it well-suited for threading operations that require precise thread geometry in a single helical pass. The 3\/8-inch shank provides a stable interface with standard toolholders. An EgiAs coating reduces friction and extends tool life in production environments. This mill is intended for use in CNC machining centers operated by skilled machinists or tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is used in shop environments where UNEF thread forms are required, including aerospace, automotive, and precision mechanical assembly applications. It handles both internal and external threading in one tool, reducing the need for separate taps or dies in certain setups. Typical applications include threading aluminum, steel, and other machinable materials where 1\/2-28 UNEF thread engagement is specified. At 28 teeth per inch, it is optimized for fine-pitch threading work where thread accuracy and surface finish are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCuts 1\/2-28 UNEF threads in both internal and external configurations\u003c\/li\u003e\n  \u003cli\u003e5 right-hand helical flutes for stable chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eEgiAs coating for reduced friction and extended tool life\u003c\/li\u003e\n  \u003cli\u003e0.343-inch cutting diameter with 1.107-inch length of cut\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank diameter for compatibility with standard CNC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or production thread mill for CNC machining centers using standard 3\/8-inch toolholders where 1\/2-28 UNEF thread milling capability is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread mills of this type are installed and operated by trained machinists on CNC milling centers. Ensure the toolholder is properly torqued and the tool is secured before spindle operation. Program helical interpolation paths according to the thread specification before running; incorrect toolpath programming is a leading cause of thread form error and tool breakage. Inspect the cutting edges before each use and replace the tool at first sign of edge wear to maintain thread quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Internal and External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.343 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.107 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: EgiAs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.375 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112806\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1662501417\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732538458418,"sku":"1662501417","price":215.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0954cad9cc2778f8965eed34539eda90_9ccf5c52-332d-45a1-84b0-acb70d42bd7b.jpg?v=1788744185","url":"https:\/\/voomisupply.com\/products\/osg-1662501417-thread-mill-1-2-28-unef-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
