It features a 1\/2-inch diameter, a 7\/8-inch length of cut, and a 6-inch overall length, with a 1\/2-inch straight cylindrical shank held to h6 tolerance. The submicron carbide substrate is coated with AlTiCrSiN via PVD process, delivering high wear resistance and thermal stability at elevated cutting speeds. Five flutes with a variable index and spiral flute geometry support both roughing and finishing operations in a single tool. This end mill is intended for use in CNC machining centers by skilled machinists and tooling specialists working in high-performance production environments.\u003c\/p\u003e\u003cp\u003eThe 3398649 fits short-reach applications while the extended reach length of 4.125 inches accommodates deeper pockets and complex part geometries. It is well suited for milling hardened and difficult-to-cut workpiece materials including P, M, K, S, and H material grades as classified by ISO cutting material standards. The right-hand flute direction and right-hand cutting direction are standard for conventional spindle configurations. Normal pitch geometry and spiral flute design contribute to stable chip evacuation across a range of feed and speed conditions. This end mill mounts directly in a compatible toolholder and is sold as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with submicron material grade for extended tool life in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eAlTiCrSiN PVD coating provides high-temperature oxidation resistance and reduced friction during high-speed cuts\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter during aggressive material removal\u003c\/li\u003e\n\u003cli\u003e5-flute spiral geometry supports both roughing and finishing in steel, stainless steel, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003cli\u003eExtended reach of 4.125 inches enables access to deep pockets and recessed features\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with h6 tolerance ensures consistent runout and secure toolholder engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard toolholders accepting a 1\/2-inch straight cylindrical shank. Suitable for CNC machining centers running workpiece materials classified as ISO P, M, K, S, and H including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Refer to the ISCAR ECI-5-VF series catalog number ECI-5 .5-.88\/4.13CVF6 for full application pairing guidance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with CNC toolholder setup procedures. Ensure the machine spindle is fully stopped and the controller is in a safe state before inserting or removing the end mill. Seat the shank fully into the toolholder bore and torque the retention mechanism according to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, particularly when working with hard or abrasive workpiece materials where tool deflection tolerances are tight.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (1.875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 4.125 inches\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, 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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCentercutting\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\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECI-5-VF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.73 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.5 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\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: 3398649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748683153714,"sku":"3398649","price":220.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2251c9666d0c1dad319752becd92272_caa078a1-1afb-4d16-885d-bec2b3aa351e.jpg?v=1788896643","url":"https:\/\/voomisupply.com\/products\/iscar-3398649-corner-radius-end-mill-1-2-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
