Part of the ECI-5-VF series, it carries a 3\/4 inch cutting diameter across 5 flutes with a 1-1\/4 inch length of cut and a 5 inch overall length. The AlTiCrSiN PVD coating delivers high heat and wear resistance, making this tool suitable for both roughing and finishing operations. A variable index design reduces chatter and improves surface finish. The submicron carbide grade adds toughness at the cutting edge, extending tool life in challenging workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in CNC machining centers and milling machines where extended reach is required. The 3 inch reach length allows access to deeper features without sacrificing rigidity. The straight-cylindrical shank at 3\/4 inch diameter with h6 tolerance provides consistent, accurate seating in standard toolholders. It is suited for shops running production work on P, M, K, S, and H material classes, including aerospace alloys and hardened steels. A right-hand flute direction and right-hand cutting geometry are standard. The tool is single-end and centercutting is not specified for this configuration, so plunge routing should be avoided unless confirmed for the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrSiN PVD coating for high-temperature wear resistance in hard and exotic materials\u003c\/li\u003e\n  \u003cli\u003e5-flute variable index geometry reduces vibration and improves finish on roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade provides edge toughness for interrupted cuts and difficult alloys\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 3 inches allows milling in deep pockets and cavities\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 tolerance ensures precise fit in standard milling toolholders\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with normal pitch for efficient chip evacuation in steel and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard milling toolholders accepting a 3\/4 inch straight-cylindrical shank. ISCAR catalog reference ECI-5 .75-1.25\/3.CVF5 identifies this tool within the ECI-5-VF series. Suitable for primary workpiece materials coded P, M, K, S, and H: carbon steel, stainless steel, cast iron, superalloys, titanium, and hard materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Secure the shank fully into the toolholder to the recommended gauge length before tightening to prevent pullout under load. Confirm the toolholder bore tolerance is compatible with the h6 shank before seating. Do not use this tool for plunge milling without first verifying centercutting capability for the intended operation, as centercutting is not confirmed for this configuration.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank 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 (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\u003ePitch\u003c\/strong\u003e: Normal\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ECI-5-VF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.51 inches L x 1.1 inches W x 1.1 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.36 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 3398643\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748615422258,"sku":"3398643","price":357.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2251c9666d0c1dad319752becd92272_a39d5a56-d035-4b5e-bd1b-33078cd4aa4a.jpg?v=1788895760","url":"https:\/\/voomisupply.com\/products\/iscar-3398643-corner-radius-end-mill-3-4-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
