Built to IC900 material grade, this single-end tool features six flutes with a 45-degree right-hand helix, providing smooth chip evacuation and superior surface finish on a wide range of workpiece materials. The cutting diameter is 0.375 inches with a 1.5-inch length of cut, and the tool measures 4 inches overall. A TiAlN coating increases heat resistance and extends tool life in high-speed and dry-cutting environments. Installation and operation are performed by machinists and CNC operators working in precision metal fabrication shops.\u003c\/p\u003e\n\u003cp\u003eThis end mill is classified as a long-series tool, making it suitable for applications that require extended reach into deeper cavities, pockets, or slots. The straight-cylindrical shank diameter of 0.375 inches fits standard collet chucks and end mill holders used in vertical and horizontal machining centers, as well as manual milling machines. The right-hand cutting direction is conventional for most CNC milling operations. Compatible workpiece material codes include H, K, M, P, and S, covering hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys. The spiral flute geometry promotes consistent chip flow during slotting, profiling, and peripheral milling passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide IC900 grade construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for elevated heat resistance and extended tool life in high-speed or dry cutting\u003c\/li\u003e\n  \u003cli\u003eSix flutes with 45-degree right-hand helix for efficient chip evacuation and smooth finish\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut (1.5 inches) suited for deeper pocket and slot milling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (0.375 inches) for compatibility with standard collet and end mill holder systems\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; non-center-cutting geometry — not intended for plunge drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on workpiece materials coded H, K, M, P, and S, including hardened steels, cast irons, stainless steels, carbon and alloy steels, and high-temperature superalloys.

Secure the shank fully within the collet or end mill holder to the recommended engagement depth before tightening. Because this end mill is non-center-cutting, do not use it for direct plunge cuts — ramp or helical entry paths are required for pocket starts. Verify spindle speed, feed rate, and depth of cut against the manufacturer cutting data for IC900 grade tooling before beginning the 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 (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: IC900\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Workpiece Material Codes\u003c\/strong\u003e: H, K, M, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 5620963\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51752951087410,"sku":"5620963","price":208.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/efddf199ddb4db5435c8e2653197c0d6.jpg?v=1788931437","url":"https:\/\/voomisupply.com\/products\/iscar-5620963-square-end-mill-3-8-in-6-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
