Built on OSG Series 3790, it features an Exocarb WXL PVD coating that improves wear resistance and heat management in pre-hardened and hardened steels. The mill diameter is 1.50 mm (0.0591 inches) with a 0.75 mm nose radius, a 30-degree helix angle, and a 2-flute helical configuration optimized for both roughing and finishing passes. The ultra-fine micrograin carbide substrate supports edge sharpness and rigidity at this small diameter. Overall length is 45 mm with a 4 mm straight-cylindrical shank held to h6 tolerance.\u003c\/p\u003e\n\u003cp\u003eThis end mill is sized for precision work in die and mold machining, micro-feature milling, and fine-detail contouring where tight tolerances are required. The extended-reach geometry, with a 12.00 mm reach length and a reduced neck diameter of 1.45 mm, allows access to deep or narrow pockets without tool interference. Suitable for machining steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium. Right-hand cut and right-hand flute direction. Coolant-through is not supported on this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWXL PVD coating for extended tool life in hardened and pre-hardened steels\u003c\/li\u003e\n  \u003cli\u003eUltra-fine micrograin solid carbide substrate for edge integrity at small diameters\u003c\/li\u003e\n  \u003cli\u003eExtended-reach design with 12.00 mm reach length and 1.45 mm neck diameter\u003c\/li\u003e\n  \u003cli\u003e30-degree medium helix angle supports stable chip evacuation in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e2-flute helical geometry rated for both roughing and finishing operations\u003c\/li\u003e\n  \u003cli\u003e4 mm shank with h6 tolerance for precise collet retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 4 mm straight-cylindrical shank. Primary workpiece materials include steel, stainless steel, cast iron, and hard materials (ISO material codes P, M, K, H). Secondary workpiece materials include non-ferrous metals and superalloys including titanium (ISO codes N, S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the shank in a precision collet or tool holder rated for the 4 mm diameter and verify runout before operation. Confirm spindle speed and feed rate settings are appropriate for the 1.50 mm cutting diameter before engaging the workpiece. Coolant-through is not available on this tool; external coolant or air blast is recommended when machining hard or abrasive materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.50 mm (0.0591 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.20 mm (0.0472 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 45.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 1.45 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 10.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.75 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Ultra Fine Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WXL (PVD)\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\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3790\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\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: 3111612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743330173234,"sku":"3111612","price":119.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63e74e50eaefd253880a4a9d9a6e4f6f.jpg?v=1788845721","url":"https:\/\/voomisupply.com\/products\/osg-3111612-ball-end-mill-0-0591-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
