With a 5\/8 inch (0.625 inch) cutting diameter and a 1\/8 inch (0.125 inch) corner radius, it produces smooth, radiused edges while maintaining tight tolerances. The 3-flute, right-hand spiral geometry supports both roughing and finishing operations in a single tool. A DLC (Diamond-Like Carbon) PVD coating reduces friction and improves tool life in aluminum, copper, and similar non-ferrous workpiece materials. The 4 inch overall length and extended reach design make it suitable for deeper cavity and pocket work. Installed in CNC machining centers or manual mills, this end mill fits a standard straight-cylindrical toolholder.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in non-ferrous metal machining applications, including aluminum alloys, brass, and copper. The coarse pitch, 3-flute configuration promotes chip evacuation in high-speed cutting conditions common in production and job-shop environments. The centercutting design allows for plunge entry. With a 1 inch length of cut, a 2 inch reach length, and a 5\/8 inch shank diameter, it fits standard toolholders used in CNC vertical and horizontal machining centers. It is part of the ISCAR ECAI-B3-EC series, catalog number ECAI-B3 .625-1\/2CR125-4EC, built from submicron carbide grade for consistency in high-volume runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8 inch cutting diameter with 1\/8 inch corner radius for radiused edge profiles\u003c\/li\u003e\n\u003cli\u003eSolid carbide submicron grade construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eDLC PVD coating optimized for non-ferrous metal cutting\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral, coarse pitch for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports plunge milling entry\u003c\/li\u003e\n\u003cli\u003eExtended reach with 2 inch reach length for deeper pocket access\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders.

Ensure the machine spindle is fully stopped and locked out before tool changes. Verify runout with a dial indicator after seating the tool, as excessive runout reduces tool life and surface finish quality in finishing passes. Follow the machine tool manufacturer torque specifications for the toolholder retention knob.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (0.3750 inches effective)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: DLC (Diamond-Like Carbon), PVD applied\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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eExtended Reach\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\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\u003eSeries\u003c\/strong\u003e: ECAI-B3-EC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3399070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51727350071602,"sku":"3399070","price":331.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/779d84f7690709a8c18604267d4f1519.jpg?v=1788676609","url":"https:\/\/voomisupply.com\/products\/iscar-3399070-corner-radius-end-mill-5-8in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
