It features a 3\/16-inch (0.1870 inch) cutting diameter and a 0.015-inch corner radius that helps reduce chipping at the cutting edge and extend tool life in high-cycle applications. The tool carries a DLC (Diamond-Like Carbon) PVD coating applied for improved hardness and low friction when cutting aluminum and other non-ferrous workpiece materials. With three right-hand spiral flutes and a coarse pitch, the 3399023 evacuates chips efficiently at aggressive feed rates. It is installed by machinists and tool-and-die professionals in CNC milling centers and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use on non-ferrous metals including aluminum, copper, and brass alloys in short-reach, high-precision milling scenarios. It belongs to the ISCAR ECAI-B3-EC series and is cataloged under ISCAR manufacturer catalog number ECAI-B3 .187-.3CR015-2EC. The extended-reach geometry and centercutting capability make it suitable for slotting, profiling, and plunge-entry operations without a pre-drilled pilot hole. It mounts in a standard straight-bore toolholder accepting a 3\/16-inch shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDLC (Diamond-Like Carbon) PVD coating for low-friction cutting in non-ferrous applications\u003c\/li\u003e\n  \u003cli\u003e0.015-inch corner radius reduces edge chipping and improves corner durability\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eThree right-hand spiral flutes with coarse pitch for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade for fine grain structure and edge toughness\u003c\/li\u003e\n  \u003cli\u003eSingle-end, straight-cylindrical shank fits standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 3\/16-inch shank diameter.

Ensure the toolholder bore and shank are clean and free of chips or coolant residue before seating the end mill. Verify runout after clamping to protect both the tool and the workpiece. This tool is not rated for coolant-through delivery; external coolant or air blast should be directed at the cutting zone.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1870 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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.3200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1870 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: DLC (PVD)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\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\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\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: 3399023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51728687759666,"sku":"3399023","price":69.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f4db0e48a1997cfe5dd176c66a02da0_7c7001ad-a1d3-400a-92b0-db1bf7687e64.jpg?v=1788695023","url":"https:\/\/voomisupply.com\/products\/iscar-3399023-corner-radius-end-mill-3-16in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
