It produces UN-standard external threads at 9 teeth per inch (TPI) with a cutting diameter of 0.59 inches and a length of cut of 1.5 inches. The 5\/8-inch shank provides rigid tool holding in standard end mill chucks and collet holders. A TiAlN coating delivers elevated heat resistance and extended tool life in ferrous and hard-material applications. Three right-hand helical flutes provide smooth cutting action and efficient chip evacuation. This tool is intended for use by machinists and tooling specialists on production or job-shop CNC milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is suited for machining external UN threads on workpieces where single-point threading or tapping is impractical. It is appropriate for use on CNC machining centers capable of helical interpolation. The minimum nominal diameter it can thread is 0.84 inches, making it well-matched for 7\/8-inch external thread profiles in steel, stainless steel, cast iron, and similar materials. Applications include production threading of fastener bosses, flanges, fittings, and mechanical components in aerospace, oil and gas, and general manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and dimensional stability in demanding cutting conditions\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for high-temperature resistance and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3 right-hand helical flutes for smooth chip evacuation during thread milling cycles\u003c\/li\u003e\n  \u003cli\u003eUN thread standard with 9 TPI for compatibility with common inch-series external thread profiles\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch shank diameter fits standard collet chucks and end mill holders\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through design — suitable for flood or mist external coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on CNC machining centers with helical interpolation capability for producing 7\/8-inch UN external threads at 9 TPI with a minimum nominal diameter of 0.84 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the machine in a safe, locked-out state per applicable shop safety procedures. Secure the 5\/8-inch shank in a balanced, properly torqued collet or end mill holder before use. Verify CNC program parameters for helical interpolation pitch and direction before cutting. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 9 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: TiAlN\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: 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5603929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51733469004082,"sku":"5603929","price":622.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5befcdd60fcebe327eb5797170f23b7_d5c77847-8e51-4c76-a96f-bd89a78ada55.jpg?v=1788755697","url":"https:\/\/voomisupply.com\/products\/iscar-5603929-helical-flute-thread-mill-7-8-ext-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
