Built on OSG Series 3790, it features a 1.00 mm (0.0394 inch) mill diameter with a 0.80 mm (0.0315 inch) length of cut and a 0.50 mm nose radius. The WXL PVD coating provides enhanced wear resistance and heat management at the cutting edge. With an ultra-fine micrograin carbide body and a 30-degree medium helix, this end mill delivers consistent results during both roughing and finishing passes. A licensed machinist or CNC programmer typically selects this tool for close-tolerance work in pre-hardened and hardened steels.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers running steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium. The extended-reach geometry, with a 16.00 mm reach length and a 0.95 mm neck diameter, allows access to deep or restricted features without sacrificing rigidity. The 4.00 mm straight-cylindrical shank with h6 tolerance provides secure, repeatable tool holding in standard collet or shrink-fit systems. It is a single-end, right-hand cutting tool intended for high-precision applications where tool life and surface finish consistency are critical.\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 construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eExtended-reach design with 16.00 mm reach length and 0.95 mm neck diameter\u003c\/li\u003e\n\u003cli\u003e2-flute, right-hand helical geometry supports both roughing and finishing operations\u003c\/li\u003e\n\u003cli\u003e4.00 mm shank with h6 tolerance for precise, repeatable tool holding\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker, no coolant-through  -  suited for dry or mist-assisted cutting strategies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 4.00 mm collet or shrink-fit toolholders on CNC machining centers.

Secure the shank fully within the toolholder to the manufacturer-recommended grip length before tightening. Verify runout at the cutting end before engaging the workpiece, as excessive runout will accelerate edge wear on a tool of this diameter. Always confirm spindle speed and feed rate parameters are appropriate for the workpiece material hardness before initiating a cut.\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\u003eOverall Length\u003c\/strong\u003e: 50.00 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 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: 15.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 16.00 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\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\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\u003eMaterial Grade\u003c\/strong\u003e: Ultra Fine Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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: 3111116\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739370815794,"sku":"3111116","price":140.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3b87ddb0d83774172c4b6f89ffbe729.jpg?v=1788813717","url":"https:\/\/voomisupply.com\/products\/osg-3111116-ball-end-mill-0-0394-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
