With a 3\/8 inch cutting diameter and a 1-1\/2 inch length of cut, it handles slotting, profiling, and peripheral milling across a range of ferrous and non-ferrous materials. The 5-flute configuration increases feed rates and improves surface finish compared to standard 4-flute tools. A 38-degree helix angle promotes smooth chip evacuation and reduces cutting forces. The TiAlCN coating adds heat resistance and wear protection, extending tool life in demanding applications. This end mill is installed and operated by machinists and tool-and-die professionals working on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits general-purpose and production milling tasks in job shops, manufacturing facilities, and tool rooms. The variable index geometry helps reduce vibration and chatter during cuts, making it a practical choice for finishing passes and semi-finishing operations. The right-hand cutting direction and right-hand spiral flutes are standard for most vertical and horizontal CNC setups. The single-end design and 3\/8 inch shank diameter make it compatible with standard collet chucks and end mill holders commonly found in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5 flutes for higher feed rates and improved surface finish relative to 4-flute tools\u003c\/li\u003e\n  \u003cli\u003e38-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eTiAlCN coating provides heat and wear resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces vibration and chatter during milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade substrate supports use in demanding, high-speed applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8 inch collet chucks and end mill holders on CNC machining centers and manual milling machines configured for right-hand cutting tools.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine powered down or in a safe mode. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specification to prevent tool pullout. Inspect the shank and collet for wear or contamination before seating the tool. Follow applicable shop safety protocols and machine guarding requirements during operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (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: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3398529\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51731932840242,"sku":"3398529","price":123.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_fecf213a-ed6e-4740-9db5-8b6785ba4088.jpg?v=1788736839","url":"https:\/\/voomisupply.com\/products\/iscar-3398529-square-end-mill-3-8-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
