Built on OSG's Series 3690 Exocarb platform, this single-end tool carries a 0.125 inch cutting diameter with a matching 0.125 inch length of cut and a 3.0 inch overall length. The WXL PVD coating is applied over an ultra-fine micrograin carbide substrate, delivering thermal resistance and edge retention during both roughing and finishing passes. The 30-degree medium helix geometry promotes chip evacuation while maintaining rigidity in extended-reach applications. Licensed machinists and CNC programmers working in job shops, tool rooms, and production machining environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, hard materials, non-ferrous metals, and superalloys including titanium. The extended-reach configuration with a 1.25 inch reach length and a reduced neck diameter of 0.123 inches allows access to deep features, pockets, and contoured surfaces that standard-length tools cannot reach. The straight cylindrical shank with h6 tolerance fits standard collet chucks and end mill holders. Right-hand cut and right-hand flute direction conform to conventional CNC milling setups. This tool does not support coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWXL PVD coating over ultra-fine micrograin carbide substrate for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eExtended-reach design with 1.25 inch reach length and 0.123 inch neck diameter for deep-feature access\u003c\/li\u003e\n  \u003cli\u003e2-flute helical geometry supports both roughing and finishing operations in a single tool\u003c\/li\u003e\n  \u003cli\u003e30-degree medium helix angle promotes chip flow and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eBall nose profile generates true radii on contoured surfaces and 3D milled features\u003c\/li\u003e\n  \u003cli\u003eShank diameter tolerance h6 ensures consistent fit in precision collet and shrink-fit holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe OSG 36901311 is compatible with primary workpiece materials coded P, M, K, and H (steel, stainless steel, cast iron, and hard materials) and secondary materials coded N and S (non-ferrous metals, superalloys, and titanium), as specified by OSG for the Series 3690 Exocarb WXL product line.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. Before mounting, confirm the spindle is at a full stop and all machine axes are locked or homed per shop safety procedures. Seat the 0.25 inch straight-cylindrical shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout with a dial indicator before engaging the workpiece, as extended-reach tools are sensitive to holder concentricity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.125 inches\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: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.123 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0625 inches\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WXL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\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: 3690\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: 36901311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754020274482,"sku":"36901311","price":124.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee3ed194729fcab1ac439b5116cfd0ab.jpg?v=1788942984","url":"https:\/\/voomisupply.com\/products\/osg-36901311-ball-end-mill-0-125-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
