Built to the IC900 material grade with a PVD-applied AlTiN coating, this single-end tool measures 3\/8 inches in diameter with a 0.437-inch length of cut and a 3-inch overall length. Three right-hand helical flutes at a 38-degree helix angle provide an efficient balance of chip evacuation and surface finish. The straight cylindrical shank is 3\/8 inches in diameter, and the extended-reach design supports access to deeper features. Licensed machinists and CNC operators working in job shops or production environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for both roughing and finishing operations across a range of workpiece materials including steel, stainless steel, and cast iron as primary targets, with secondary capability in non-ferrous metals, superalloys, titanium, and hard materials. Supported operations include shouldering, slotting, ramp-down entry, helical interpolation, drill milling, plunging, and recessing. The short flute length and normal pitch make it a reliable choice for general-purpose milling in vertical machining centers and CNC mills where rigidity and repeatability are priorities. This tool carries the ISCAR catalog designation ECSI-E-3 375-437-C375 and belongs to the ECSI-E-3 series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide IC900 grade construction for wear resistance in ferrous and difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating extends tool life in high-temperature cutting environments\u003c\/li\u003e\n  \u003cli\u003e38-degree medium helix angle supports smooth chip flow and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 0.910-inch reach length and 0.354-inch neck diameter for accessing recessed features\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, enabling plunging and drill-mill operations without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eSupports six operation types: shouldering, slotting, ramp-down, helical interpolation, drill milling, and plunging\/recessing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8-inch straight-shank tool holders on CNC vertical machining centers and manual mills.

Secure the straight cylindrical shank in a collet chuck or end mill holder to the appropriate clamping torque specified by the toolholder manufacturer. Verify runout with a dial indicator before commencing a cut, as excessive runout accelerates coating wear and reduces tool life. Always bring spindle to a full stop before tool changes.\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.437 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.354 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.910 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 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\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\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECSI-E-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCatalog Number\u003c\/strong\u003e: ECSI-E-3 375-437-C375\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.637 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: 5620945\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750675579186,"sku":"5620945","price":96.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29b1062d58822f4e30be4f069eeac819_d3c276cb-7f37-42b1-b1d9-ea3e5fd74858.jpg?v=1788918256","url":"https:\/\/voomisupply.com\/products\/iscar-5620945-corner-chamfer-end-mill-3-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
