With a 0.0394 inch (1.00 mm) mill diameter and a 0.0315 inch (0.80 mm) length of cut, this tool is built for precision work in tight geometries and fine features. The WXL PVD coating enhances wear resistance and thermal stability, making it suitable for cutting pre-hardened and hardened steels. Two helical right-hand flutes and a 30-degree helix angle provide efficient chip evacuation during both roughing and finishing passes. The ultra-fine micrograin carbide substrate supports edge integrity at elevated cutting speeds.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers handling steel, stainless steel, cast iron, hard material, non-ferrous metal, superalloys, and titanium. The extended reach configuration, combined with a 0.95 mm neck diameter and a 9.20 mm neck length, allows access to features with deeper wall clearance requirements. It is a single-end tool with a straight-cylindrical 4.00 mm shank held to h6 tolerance, making it compatible with standard collet and shrink-fit toolholding systems. Machinists and CNC programmers working with hardened die and mold materials will find this part appropriate for their finishing and semi-finishing operations. It is part of OSG Series 3790 Exocarb WXL High Performance End Mills.\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 stability at high surface speeds\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 10.00 mm reach length and 0.95 mm neck diameter for deep-feature access\u003c\/li\u003e\n  \u003cli\u003e0.50 mm nose radius for controlled ball-end contact in contour and 3D surface milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand helical flutes with 30-degree medium helix angle\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, hard material, non-ferrous metal, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 4.00 mm collet, shrink-fit, or hydraulic toolholding systems on CNC machining centers.

Ensure the toolholder is clean and free of debris before seating the shank. Verify runout with a dial indicator before beginning a production run, as tool diameter at 1.00 mm is sensitive to even minor concentricity errors. Follow machine manufacturer and OSG Series 3790 cutting data recommendations for spindle speed, feed rate, and depth of cut appropriate to workpiece hardness.\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\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: 9.20 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 10.00 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\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\u003eSeries\u003c\/strong\u003e: 3790\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\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: 3111100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743428313394,"sku":"3111100","price":106.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/44705dd95c5bbc6cf19dcfd70ba724a2.jpg?v=1788846932","url":"https:\/\/voomisupply.com\/products\/osg-3111100-ball-end-mill-0-0394-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
