Built from micrograin solid carbide with a TiAlN (titanium aluminum nitride) coating, it delivers heat resistance and extended tool life under demanding cutting conditions. The 2-flute spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 0.25 inches in diameter with a 0.5-inch length of cut and 2-inch overall length, this stub-length end mill is suited for controlled, accurate cuts in tight-envelope applications. Installation is performed by machinists and CNC operators working with vertical machining centers and manual milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in ferrous and non-ferrous metal milling operations where precise side milling, slotting, and profiling are required. The centercutting geometry allows for direct plunge entry into the workpiece without a pre-drilled hole. The stub length profile reduces deflection and increases rigidity, making it appropriate for applications where tool overhang must be minimized. Right-hand cut and right-hand flute orientation are standard for conventional spindle-driven machining centers. It belongs to OSG Series 412.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases heat resistance and extends tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e2-flute spiral design with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without pilot hole\u003c\/li\u003e\n  \u003cli\u003eStub length reduces deflection for improved accuracy in tight setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for 0.25-inch straight-shank collet holders and end mill holders used in CNC and manual milling machines requiring a 2-flute square end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Secure the shank fully into the collet or end mill holder to the recommended grip depth before torquing the retention hardware. Power down and de-energize the machine spindle completely before tool changes. Inspect the collet and holder for runout and contamination prior to seating the tool to protect both the tool and 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: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\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: 0.25 inches (1\/4 inch)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 412\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: 412-250011\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748854661426,"sku":"412-250011","price":42.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c4677d9009ad2d86c077ffe16de0273_2e00b3b5-f31a-40c9-93d1-5f4df76b1b13.jpg?v=1788899605","url":"https:\/\/voomisupply.com\/products\/osg-412-250011-square-end-mill-0-25in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
