Built on OSG's Series 3710 Exocarb WXL platform, it combines an ultra fine micrograin solid carbide substrate with a PVD-applied WXL coating engineered for rigidity and wear resistance. The mill measures 0.3937 inches (10 mm) in diameter with a 0.5906-inch (15 mm) length of cut, a 10 mm straight-cylindrical shank, and a 100 mm overall length. The 2-flute, 30-degree medium helix geometry supports both roughing and finishing passes in a single tool. Licensed machinists and CNC tooling professionals install this end mill in machining centers for precision contouring and profiling work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, and hard materials as primary workpiece materials. Secondary applications include non-ferrous metals, superalloys, and titanium. The ball nose geometry makes it effective for 3D profiling, die and mold work, and contoured surface finishing. It is intended for right-hand cutting with right-hand flute direction and does not feature coolant-through, extended reach, variable helix, variable index, or chipbreaker geometry, keeping the design focused on rigidity in standard-reach applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUltra fine micrograin solid carbide substrate for hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eWXL PVD coating designed for hard milling and broad material compatibility\u003c\/li\u003e\n  \u003cli\u003e30-degree medium helix angle balances chip evacuation with cutting stability\u003c\/li\u003e\n  \u003cli\u003e2-flute ball nose geometry supports both roughing and finishing in one tool\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC spindle use\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of plus or minus 0.01 mm and h6 shank tolerance for consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 10 mm straight-cylindrical shank.

Secure the shank fully in a collet or end mill holder to the manufacturer-specified engagement depth before operating the spindle. Verify runout with a dial indicator before cutting, and confirm spindle speed and feed rate settings are appropriate for the workpiece material and depth of cut. Never exceed the tool's stated length of cut when engaging the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5906 inches (15 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 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\u003eCoating\u003c\/strong\u003e: WXL (PVD)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus or minus 0.01 mm\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\u003eEnd Configuration\u003c\/strong\u003e: Single End\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\u003eNose Radius\u003c\/strong\u003e: 5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 15 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3710\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 3106640\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51732787593522,"sku":"3106640","price":161.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bd44d1031fb4e0711038e5f2b745a4b_a39014e9-731f-49f6-b42b-d1e343c372e9.jpg?v=1788746811","url":"https:\/\/voomisupply.com\/products\/osg-3106640-ball-end-mill-0-3937-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
