It features a 1\/2 inch diameter, a 1-1\/4 inch length of cut, and a 0.015 inch corner radius that protects the cutting edge and improves surface finish at part corners. The flute geometry runs in a right-hand spiral with a variable index design, enabling both roughing and finishing passes in a single tool. An AlTiCrSiN PVD coating delivers thermal resistance and hardness at elevated cutting temperatures. This tool is intended for use in CNC machining centers and mills operated by machinists and tool-and-die professionals working in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 3398032 is engineered for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is part of the ISCAR ECI-4-VF series, which targets extended-reach applications with a 1-1\/4 inch reach length and a 3 inch overall length. The straight cylindrical shank with h6 tolerance mounts directly into standard toolholders. Its centercutting capability allows plunge entry, and the normal pitch with spiral flutes supports chip evacuation across a range of cutting conditions. Recommended for medium-length applications where rigidity and coating performance are both required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrSiN PVD coating provides high heat resistance for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius protects flute tips and improves corner durability on finished surfaces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade substrate supports high hardness and wear resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eExtended reach geometry with 1-1\/4 inch reach length suits pockets and slots with depth requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard cylindrical toolholders accepting a 1\/2 inch straight shank with h6 diameter tolerance. Compatible with CNC machining centers and milling machines running right-hand cutting direction. Part of the ISCAR ECI-4-VF series; manufacturers catalog number ECI-4 500-1.25C015VF3.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the shank is fully seated and clean before tightening the collet or endmill holder to avoid runout that can damage the cutting edge. Verify spindle speed and feed rate settings match the workpiece material and depth of cut before engaging the tool. Do not exceed the rated length of cut when side milling, as overhanging beyond the flute length increases deflection and risk of breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.0236 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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 Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1-1\/4 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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 and 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: 3.5 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.38 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: 3398032\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51748103553330,"sku":"3398032","price":119.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76aebafa75cad44d31f5c4a0535535fb_3113f461-8e26-4cd3-8709-58dfa13a1997.jpg?v=1788889097","url":"https:\/\/voomisupply.com\/products\/iscar-3398032-corner-radius-end-mill-1-2-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
