It features a 1\/2 inch cutting diameter, a 0.06 inch corner radius, and three right-hand spiral flutes with a coarse pitch and 45-degree helix angle. The DLC (Diamond-Like Carbon) PVD coating extends tool life and reduces friction when cutting aluminum, copper, brass, and similar materials. At 4 inches overall length with a 7\/8 inch length of cut, this short-series end mill handles both roughing and finishing operations. It is center-cutting, making it capable of plunge entry. The straight-cylindrical 1\/2 inch shank fits standard toolholders used on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for non-ferrous metal cutting, including aluminum alloys, copper, and other materials in the N material grade classification. The extended reach design, with a 2-1\/8 inch reach length, allows access to deeper features without sacrificing rigidity. The single-end configuration suits production environments and job shops running CNC vertical or horizontal machining centers where repeatable finishing passes and precise corner geometry are required. The ISCAR ECAI-B3-EC series, manufacturer catalog number ECAI-B3 .5-.9\/2.1CR06-4EC, is built from submicron carbide grade for consistent edge integrity across production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for edge stability in non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003eDLC PVD coating reduces built-up edge and extends tool life on aluminum and soft metals\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius blends sharp corners and improves surface finish at part edges\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 2-1\/8 inches provides access to deep pockets and stepped features\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral with coarse pitch supports chip evacuation in gummy materials\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 1\/2 inch cylindrical shank. Intended for CNC machining centers and milling machines cutting non-ferrous metals.

The shank must be fully seated and secured in a compatible toolholder or collet chuck; verify runout with a dial indicator before production use. Confirm spindle speed and feed rate parameters for the specific workpiece material before engaging the cut. Do not exceed the rated length of cut; overhang beyond the recommended depth increases deflection and risk of tool 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\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\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: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-1\/8 inches (2.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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\u003eManufacturer Catalog Number\u003c\/strong\u003e: ECAI-B3 .5-.9\/2.1CR06-4EC\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: 3399268\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51747561963826,"sku":"3399268","price":233.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f4db0e48a1997cfe5dd176c66a02da0_e3c6eca6-aa75-4cef-aa97-ebfd62ed0840.jpg?v=1788882620","url":"https:\/\/voomisupply.com\/products\/iscar-3399268-corner-radius-end-mill-1-2-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
