It carries a 1\/2 inch cutting diameter, a 1-1\/2 inch length of cut, and a 0.015 inch corner radius that extends tool life at the cutting edge. The AlTiCrSiN PVD coating provides thermal resistance and wear protection in high-speed cutting environments. With a variable index geometry and right-hand spiral flute direction, the 3398033 reduces chatter and improves chip evacuation. It is installed and operated by machinists and CNC tool-room technicians in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The centercutting design allows plunge entry, making it useful for slotting, profiling, and pocket milling operations. The extended reach configuration with a 1-1\/2 inch reach length supports work in deeper cavities or against stepped part features. It is compatible with standard straight-shank toolholders accepting a 1\/2 inch shank diameter with h6 tolerance, which is common in ISO and ANSI collet systems used in CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiCrSiN PVD coating for high thermal and wear resistance in difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces edge chipping and extends tool life at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eVariable index flute geometry minimizes vibration and chatter during roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled lead hole\u003c\/li\u003e\n  \u003cli\u003eExtended reach geometry with 1-1\/2 inch reach length for access in deeper cavities\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade provides rigidity and edge integrity at elevated cutting temperatures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-shank toolholders accepting a 1\/2 inch shank diameter. Compatible with workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials per ISO material codes P, M, K, S, and H.

Ensure the machine spindle is fully stopped and the tool is secured in a clean, properly sized collet or toolholder before tightening. Verify runout with a dial indicator after seating, as excessive runout accelerates wear on a corner radius geometry. Follow the machine tool manufacturer and ISCAR cutting data recommendations for feed rate, depth of cut, and spindle speed when transitioning between roughing and finishing passes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 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\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.0236 inches decimal)\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: 0.5 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: 1-1\/2 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 Spiral\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 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\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-4-VF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.51 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: 3398033\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51744871350578,"sku":"3398033","price":134.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76aebafa75cad44d31f5c4a0535535fb_ccc86660-ca5d-4b02-81e8-9d8b58f25a8d.jpg?v=1788861780","url":"https:\/\/voomisupply.com\/products\/iscar-3398033-corner-radius-end-mill-1-2-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
