It features a 3\/8-inch diameter, a 0.0600-inch corner radius, and five flutes with a right-hand spiral and right-hand cutting direction. The tool carries an AlTiCrSiN PVD coating, which provides thermal and wear resistance suited to aggressive cutting conditions. With a variable index geometry and extended reach configuration, it is built to handle both roughing and finishing operations in a single setup. Licensed machinists and CNC operators in production and job-shop environments rely on this tool for consistent, repeatable performance.\u003c\/p\u003e\n\u003cp\u003eThe 3398423 is designed for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its submicron carbide grade and AlTiCrSiN coating make it particularly effective in high-heat, high-load conditions common in aerospace, die and mold, and general machining applications. The single-end, straight-cylindrical shank with h6 tolerance fits standard toolholders and collet-style workholding setups. It is suited to CNC machining centers running demanding cycles where tool life and surface finish consistency are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrSiN PVD coating for enhanced heat resistance and extended tool life in hard and exotic materials\u003c\/li\u003e\n  \u003cli\u003eFive-flute variable index design reduces harmonic vibration during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003e0.0600-inch corner radius reduces stress concentration and improves edge durability\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade provides a fine, consistent grain structure for sharp, stable cutting edges\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 1-inch length of cut and 2.5-inch overall length suits deeper pocket and shoulder milling\u003c\/li\u003e\n  \u003cli\u003eCapable of roughing and finishing operations, reducing tool changes in multi-stage programs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank toolholders.

Power down and lock out the spindle before changing or seating the tool in the toolholder. Verify shank seating depth and runout with a dial indicator before beginning cuts, as improper seating in the holder can accelerate edge wear. Follow machine tool manufacturer specifications for maximum RPM, feed rate, and depth of cut for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\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\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eChipbreaker\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-5-VF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.99 inches L x 0.63 inches W x 0.63 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 3398423\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51732237189426,"sku":"3398423","price":106.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f2251c9666d0c1dad319752becd92272_9deac0d1-336e-40ab-ab7d-2ea1c043641b.jpg?v=1788740735","url":"https:\/\/voomisupply.com\/products\/iscar-3398423-corner-radius-end-mill-3-8in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
