It features a 7\/16 inch (0.4370 inch) cutting diameter, a 1\/8 inch (0.1250 inch) corner radius, and a 2 inch length of cut, with a 4 inch overall length. The three-flute, right-hand spiral geometry with a coarse pitch supports both roughing and finishing operations in a single tool. A DLC (Diamond-Like Carbon) PVD coating provides wear resistance and low friction suited to non-ferrous workpiece materials. The straight cylindrical shank mounts directly into a compatible toolholder for secure, repeatable setup.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use on CNC machining centers and milling machines processing non-ferrous metals such as aluminum, copper, and brass alloys. The extra-long reach configuration and extended 2 inch reach length make it well suited for deep-pocket milling, slotting, and profiling operations where standard-length tools cannot access the workpiece. It is specified as part of the ISCAR ECAI-B3-EC series and carries catalog number ECAI-B3 .437-2CR125-4EC. Machinists and CNC operators working in job shop and production environments are the primary installers of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and edge retention in non-ferrous milling\u003c\/li\u003e\n  \u003cli\u003eDLC PVD coating reduces friction and built-up edge when cutting aluminum and other non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch corner radius protects the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n  \u003cli\u003eThree-flute coarse-pitch geometry supports chip evacuation during roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eExtra-long reach with 2 inch reach length enables deep-pocket and extended-reach milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard toolholders accepting a 7\/16 inch straight cylindrical shank. Part of the ISCAR ECAI-B3-EC series; manufacturer catalog number ECAI-B3 .437-2CR125-4EC.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before mounting. Tighten the toolholder to the spindle and secure the end mill shank to the manufacturer-specified clamping torque for the toolholder type in use. Verify runout with a dial indicator before commencing a cut, particularly given the extra-long reach of this tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inches (0.4370 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inches (0.4370 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2 inches\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: DLC (Diamond-Like Carbon), 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: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECAI-B3-EC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 3399085\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51746476097842,"sku":"3399085","price":184.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/779d84f7690709a8c18604267d4f1519_eb455e5a-23b7-4409-8381-c96db435ea95.jpg?v=1788870691","url":"https:\/\/voomisupply.com\/products\/iscar-3399085-corner-radius-end-mill-7-16-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
