Built to Series 2215 standards, it features a 3\/8-inch diameter with a 0.06-inch corner radius and 7 helical flutes at a 38-degree high helix angle. The extra-long geometry delivers a 2-1\/2-inch length of cut and 6-inch overall length, giving machinists extended reach in deep-pocket and long-reach milling scenarios. The FX3 AlCr-based coating is engineered to extend tool life when cutting ferrous and hard-to-machine materials. This is a single-end, right-hand cut and flute tool with a straight cylindrical shank held to h6 tolerance, intended for installation in standard end mill holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish milling operations on steel, stainless steel, superalloys, titanium, and cast iron. Its close-pitch, 7-flute configuration supports smooth surface finishes and efficient chip evacuation at controlled feed rates. The extra-long length of cut makes it appropriate for deep-wall pockets, tall workpiece features, and profiling operations where standard-length tooling cannot reach. It is center-cutting, which allows plunge entry where required. Machinists working in aerospace, die-mold, and general precision machining environments will find this tool well matched to tight-tolerance finishing passes on difficult materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute close-pitch helical geometry optimized for finishing passes on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003e0.06-inch corner radius reduces stress concentration and extends edge life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eExtra-long 6-inch overall length with 2-1\/2-inch length of cut for deep-reach applications\u003c\/li\u003e\n  \u003cli\u003eSubmicron-grade solid carbide substrate with FX3 AlCr coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eHigh 38-degree helix angle promotes smooth cutting action and chip flow\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank to h6 tolerance for precise runout control in end mill holders\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows axial plunge entry where needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders accepting a 3\/8-inch straight cylindrical shank.

Seat the shank fully in the end mill holder and torque the set screw or collet nut per the holder manufacturer specification. Verify runout with a dial indicator before beginning a finishing pass, as tool deflection is amplified at extended reach lengths. Do not exceed the recommended axial and radial depth of cut for the specific workpiece material without confirming with toolpath simulation.\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 \/ 9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/2 inches (63.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.40 mm)\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\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FX3 AlCr\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees (High)\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 Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 312614\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51986597249330,"sku":"312614","price":246.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73a005d5ba50d83229d91438d40f4ca3_dfb06b3e-c672-4850-bb97-3352120fedc3.jpg?v=1789986251","url":"https:\/\/voomisupply.com\/products\/gws-312614-corner-radius-end-mill-3-8-in-7-flutes-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
