Built on OSG's Series 9010 Exocarbmax platform, this tool features a 1\/16 inch cutting diameter with a 3\/32 inch length of cut and five flutes in a right-hand spiral configuration with a 30-degree helix angle. The WXS PVD coating provides thermal resistance and extended tool life in demanding metal-removal operations. At 2 inches overall length with a 1\/4 inch straight-cylindrical shank, this stub-length mill fits standard collet chucks and tool holders used in CNC machining centers and manual mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finish and roughing passes in steel, cast iron, stainless steel, superalloys, and titanium. Its stub-length design improves rigidity, making it appropriate for tight-tolerance work in die and mold applications, aerospace components, and precision machining of hardened workpieces. The ultra-fine micrograin carbide substrate supports the tool geometry needed for small-diameter work at elevated surface footage. Secondary workpiece materials include stainless steel and superalloys, expanding its utility across a range of shop applications requiring a small-diameter ball profile.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUltra-fine micrograin solid carbide substrate for strength at small diameters\u003c\/li\u003e\n  \u003cli\u003eWXS PVD coating rated for hardened steels over 55 Rc\u003c\/li\u003e\n  \u003cli\u003eFive-flute right-hand spiral design supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003e30-degree medium helix angle balances chip evacuation and cutting force\u003c\/li\u003e\n  \u003cli\u003eStub-length construction maximizes rigidity and minimizes deflection in precision cuts\u003c\/li\u003e\n  \u003cli\u003e0.0313 inch nose radius provides accurate ball-end profile for contoured surface work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 1\/4 inch straight-cylindrical shank.

Secure the 1\/4 inch shank in a collet or end mill holder rated for the intended RPM and feed load; verify runout before cutting. Follow the tool manufacturer's recommended speeds and feeds for the workpiece material and hardness. Inspect the cutting edges under magnification before use, as small-diameter carbide tools are sensitive to chipping from improper handling or excessive overhang.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/32 inch (0.0938 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0313 inches\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: WXS (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 9010\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.5 inches L x 0.3 inches W x 0.3 inches H\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: 90100311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747551314226,"sku":"90100311","price":179.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/616809f87c6c2cf0f40cc084c82eb61a.jpg?v=1788882415","url":"https:\/\/voomisupply.com\/products\/osg-90100311-ball-end-mill-1-16-in-5-flute-solid-carbide-wxs","provider":"Voomi Supply","version":"1.0","type":"link"}
