With a 0.0394-inch (1.00 mm) mill diameter and a 0.0315-inch (0.80 mm) length of cut, this micro end mill is built for precision work in tight geometries. The two-flute, right-hand helical design paired with OSG WXL PVD coating delivers consistent performance across roughing and finishing passes. The ultra-fine micrograin carbide substrate supports tool life in pre-hardened and hardened steels where conventional end mills fail prematurely.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for mold and die work, aerospace component machining, and precision part manufacturing where small-diameter tooling and extended reach are required. Primary workpiece materials include steel, stainless steel, cast iron, and hard materials. Secondary applications cover non-ferrous metals, superalloys, and titanium. The extended-reach geometry and 8.00 mm reach length make it effective in cavities and deep-pocket features that standard-length tools cannot access.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWXL PVD coating optimized for pre-hardened and hardened steels\u003c\/li\u003e\n\u003cli\u003eUltra-fine micrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eExtended reach design with 8.00 mm reach length and 7.20 mm neck length\u003c\/li\u003e\n\u003cli\u003e0.50 mm nose radius for consistent ball-end profile in finishing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction, single-end configuration\u003c\/li\u003e\n\u003cli\u003eSuitable for both roughing and finishing material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OSG Series 3790 Exocarb WXL high-performance ball end mill for use in steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium workpieces per the manufacturer material classification codes P, M, K, H, N, and S.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a compatible toolholder accepting a 4.00 mm straight-cylindrical shank with h6 shank diameter tolerance. Power down and lock out the machine spindle before tool changes. Verify runout and tool projection before engaging the cut, as micro-diameter carbide tooling is sensitive to excessive overhang and spindle imbalance. Coolant-through is not supported on this tool; use external coolant or air blast as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eShank Diameter\u003c\/strong\u003e: 4.00 mm straight-cylindrical, h6 tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 45.00 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: 7.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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\u003eCoating\u003c\/strong\u003e: WXL (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3790\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3111080\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743258018098,"sku":"3111080","price":106.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4aa5490b859472732663830c1e0caa9.jpg?v=1788844660","url":"https:\/\/voomisupply.com\/products\/osg-3111080-ball-end-mill-0-0394-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
