Designed for both roughing and finishing operations, this tool features a 5\/8-inch (0.6250 inch) mill diameter, a 0.09-inch corner radius, and four flutes in a right-hand spiral configuration with a variable index geometry that improves chatter resistance. The AlTiCrSiN PVD coating provides thermal and wear resistance when cutting hard and abrasive workpiece materials. It is part of the ISCAR ECI-4-VF series and is installed by machinists and tooling technicians on CNC machining centers using compatible toolholders with Weldon flat shank mounting.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials in both shop and production environments. The single-end, centercutting design allows plunge entry and full-profile corner radius cuts. The extended reach configuration, with a 4-inch reach length and 1-inch length of cut, makes it appropriate for deeper pocket work and step-milling applications where standard-reach tools cannot access the feature geometry. It mounts to standard Weldon flat toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiCrSiN PVD coating for wear and heat resistance in steel, stainless, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003cli\u003eVariable index flute geometry reduces vibration and chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003e0.09-inch corner radius reduces stress concentration and extends tool life at part corners\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eExtended reach: 4-inch reach length supports deep pocket and step-milling applications\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank with h6 tolerance for secure, repeatable toolholder seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard Weldon flat toolholders accepting a 5\/8-inch shank diameter.

Secure the Weldon flat shank firmly in the toolholder to the appropriate clamping torque per the toolholder manufacturer specification before spindle operation. Verify runout with a dial indicator after tool mounting and before cutting to protect both the tool and the workpiece. Do not exceed the rated cutting parameters for the workpiece material class being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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: AlTiCrSiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECI-4-VF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3401206\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51747530408242,"sku":"3401206","price":306.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76aebafa75cad44d31f5c4a0535535fb_9ca3f831-05ff-4ef6-929a-6ea5b238172a.jpg?v=1788882002","url":"https:\/\/voomisupply.com\/products\/iscar-3401206-corner-radius-end-mill-5-8-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
