Built on OSG's 464BN series platform, it features a 0.125 inch cutting diameter, a 0.75 inch length of cut, and a 2.25 inch overall length with a matching 0.125 inch shank diameter. The TiCN coating improves surface hardness and wear resistance, extending tool life in abrasive materials. With four flutes and a 30-degree right-hand helix, it delivers efficient chip evacuation and a smooth finish in both slotting and profiling applications. Machinists and toolroom operators select this end mill for fine-detail contouring and finishing passes where dimensional accuracy is critical.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills running ferrous alloys, stainless steel, cast iron, and similar materials that benefit from TiCN coating. The long-series designation provides additional reach for deeper pocket work and contoured surface milling where a standard-length tool cannot access the workpiece geometry. Single-end construction with a right-hand cutting direction makes it compatible with conventional right-hand spindle setups found in most production and job shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.125 inch ball end cutting diameter for fine-detail contouring and profiling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide micrograin substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree right-hand spiral helix for efficient chip flow and finish quality\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut (0.75 inch) provides extended reach into pockets and contoured geometry\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cutting direction compatible with standard CNC and manual spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide ball end mill replacement for 0.125 inch shank collets and tool holders in standard CNC machining centers and milling machines with right-hand spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 0.125 inch shank fully and evenly in the collet or tool holder to the specified grip depth, and torque the collet nut per the tool holder manufacturer's specification. Inspect the cutting edges and TiCN coating for chips or damage before mounting.\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 464BN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 464-1250-BN08\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51787600101682,"sku":"464-1250-BN08","price":42.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37609d91bcf9f18e89375013188ef57a_def968f2-c3e3-4381-aaf7-42ab969d56e3.jpg?v=1789217479","url":"https:\/\/voomisupply.com\/products\/osg-464-1250-bn08-ball-end-mill-0-125-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
