Built to Series 3790 specifications, this single-end tool features a 1.00 mm (0.0394 inch) cutting diameter with a 0.80 mm length of cut and a 0.50 mm nose radius. The WXL PVD coating is applied specifically for pre-hardened and hardened steels, providing thermal resistance and edge durability under aggressive cutting conditions. The ultra-fine micrograin carbide substrate supports the two-flute, right-hand helical geometry at a 30-degree helix angle. CNC machinists and tool-and-die professionals rely on this geometry for both roughing and finishing passes in tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for precision milling of steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium. The extended-reach configuration, with a 3.00 mm reach length and a 0.95 mm neck diameter, allows access to deep pockets and recessed features without interference. The 4.00 mm straight-cylindrical shank with h6 tolerance provides a secure fit in standard collet systems. Typical applications include die and mold work, aerospace component machining, and high-precision part production where fine surface finishes and tight dimensional tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWXL PVD coating optimized for pre-hardened and hardened steels up to high Rockwell hardness ratings\u003c\/li\u003e\n  \u003cli\u003eUltra-fine micrograin solid carbide substrate for edge strength and wear resistance\u003c\/li\u003e\n  \u003cli\u003eExtended-reach design with 3.00 mm reach length and 0.95 mm neck diameter for deep-pocket access\u003c\/li\u003e\n  \u003cli\u003eTwo-flute, 30-degree right-hand helical geometry for balanced roughing and finishing performance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with h6 tolerance for precise collet retention\u003c\/li\u003e\n  \u003cli\u003eCompatible with steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe OSG 3111030 is designed for use in CNC machining centers and milling machines equipped with standard collet or toolholder systems accepting a 4.00 mm straight shank. Primary workpiece materials include steel, stainless steel, cast iron, and hard materials. Secondary workpiece materials include non-ferrous metals, superalloys, and titanium.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified CNC machinist or tooling technician with the machine powered down and in a safe, locked-out state. Confirm collet bore size matches the 4.00 mm shank diameter and that runout is within acceptable tolerance before use. Extended-reach tools are more sensitive to side-loading  -  verify depth of cut and feed rate parameters are appropriate for the neck diameter before initiating the program. Follow the machine tool manufacturer guidelines and applicable shop safety procedures for carbide tooling handling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0394 inches (1.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\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\u003eNose Radius\u003c\/strong\u003e: 0.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.95 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 2.20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3.00 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eVariable Helix\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\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: 3111030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743051907378,"sku":"3111030","price":88.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45d017ba360561f902835fa7ec202dc4.jpg?v=1788841977","url":"https:\/\/voomisupply.com\/products\/osg-3111030-ball-end-mill-0-0394-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
