It carries a 1-inch milling diameter, a 1-1\/2-inch length of cut, and a 0.015-inch corner radius. The four-flute, right-hand spiral geometry is coated with AlTiCrSiN via a PVD process, providing thermal resistance and edge durability at elevated cutting speeds. The variable index flute spacing reduces harmonic vibration during aggressive cuts. Overall length is 4 inches with a 1-inch straight-cylindrical shank held to an h6 tolerance. This tool is suited for roughing and finishing operations and is installed by machinists working on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use across a broad range of workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It belongs to the ISCAR ECI-4-VF series, which targets short-reach, high-rigidity applications. The centercutting geometry allows plunge entry. The extended-reach configuration and straight shank make it compatible with standard toolholder setups on vertical and horizontal machining centers in both job-shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrSiN PVD coating delivers oxidation resistance and extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces chatter and improves surface finish during high-feed passes\u003c\/li\u003e\n  \u003cli\u003e0.015-inch corner radius protects the cutting edge and reduces stress concentration at part corners\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide substrate provides toughness and wear resistance for both roughing and finishing\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 tolerance ensures secure, repeatable toolholder seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the ISCAR ECI-4-VF series. Designed for use with standard cylindrical-bore toolholders. The manufacturers catalog number for this configuration is ECI-4 1.0-1.5C015VF4. Compatible workpiece materials include 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 qualified machinist or CNC tooling technician. Power down and lock out the spindle before changing tooling. Seat the shank fully into a clean, undamaged toolholder bore and torque the retention mechanism to the toolholder manufacturers specification. Verify runout with a dial indicator before engaging the workpiece, as excess runout accelerates edge wear on variable-index geometries.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.4961 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\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\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\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\u003ePackage Dimensions\u003c\/strong\u003e: 4.49 inches L x 1.34 inches W x 1.34 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.04 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: 3398053\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51747920707890,"sku":"3398053","price":661.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76aebafa75cad44d31f5c4a0535535fb_3c7db2e6-819f-4426-8bbf-6f0d55c5f882.jpg?v=1788887094","url":"https:\/\/voomisupply.com\/products\/iscar-3398053-corner-radius-end-mill-1-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
