Built on the OSG Series 4570 platform, it features a 3 mm cutting diameter, a 0.75 mm corner radius, and four right-hand flutes with a straight flute geometry. The WXS coating improves wear resistance and heat dissipation, extending tool life in hardened and abrasive workpiece materials. With a micrograin carbide grade and centercutting capability, this tool handles both plunging and lateral cutting moves. It is a single-end tool designed for CNC machining centers and high-precision manual mills where corner geometry control is critical.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish milling, slot milling, and profiling operations in materials such as hardened steels, stainless steels, and alloys where a controlled corner radius is required to reduce stress concentration at part features. The extended reach design, with a 9 mm reach length and 2.70 mm neck diameter, allows access to deeper pockets and recessed features without tool body interference. Typical users include tool and die makers, mold machinists, and CNC operators working in precision metalworking shops. The 6 mm straight-cylindrical shank fits standard ER collet chucks and milling holders commonly found on small to mid-size machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3 mm cutting diameter with 0.75 mm corner radius for controlled edge geometry\u003c\/li\u003e\n  \u003cli\u003eWXS coating for enhanced wear resistance and tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and edge sharpness retention\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry into workpiece\u003c\/li\u003e\n  \u003cli\u003eExtended reach with 9 mm reach length and 2.70 mm neck diameter for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute, single-end configuration for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill in the OSG Series 4570 line, compatible with standard ER collet chucks and milling tool holders accepting a 6 mm straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist or CNC setup technician with the machine spindle fully stopped and the control in an emergency-stopped or locked-out state. Seat the 6 mm shank fully into the collet chuck and torque the collet nut to the tool holder manufacturer specification. Inspect the corner radius and cutting edges for chipping before each use, as micrograin carbide is rigid but brittle under side-load shock. Do not exceed the cutting parameters recommended for the workpiece material and tool diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.75 mm\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: 1.30 mm (0.0472 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 2.70 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 9 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WXS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End, Centercutting\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4570\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 457003011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736829722930,"sku":"457003011","price":166.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8838a182fb7d89b0ef8a4be2742167f.jpg?v=1788780867","url":"https:\/\/voomisupply.com\/products\/osg-457003011-corner-radius-end-mill-3mm-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
