With a 0.0781 inch (5\/64 inch) cutting diameter and a 0.1563 inch (5\/32 inch) length of cut, this stub-length tool is built for rigidity in tight setups where deflection must be minimized. The 1\/8 inch shank diameter and 1.5 inch overall length keep the tool compact. Two right-hand spiral flutes with a 30-degree helix angle promote chip evacuation and smooth cutting action. Micrograin solid carbide construction delivers hardness and wear resistance suited to ferrous and non-ferrous materials. Centercutting geometry allows plunge entry directly into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers, manual knee mills, and toolroom applications where small-diameter precision work is required. The stub length profile reduces overhang and improves rigidity when milling slots, pockets, and profiles in materials such as aluminum, brass, steel, and engineering plastics. It is typically installed and used by machinists, tool-and-die makers, and precision fabricators working with small-scale or detailed features.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003e2 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eStub length (1.5 inch OAL) provides maximum rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill in the OSG Series 412 stub-length line, compatible with any machine tool spindle accepting a 1\/8 inch straight shank tool holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists using a collet chuck or end mill holder sized for a 1\/8 inch shank. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the tool. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on small-diameter carbide tooling. Follow applicable shop safety procedures and machine manufacturer guidelines for spindle speed and feed rate selection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0781 inches (5\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1563 inches (5\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\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\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 Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 412-0781\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51740865593650,"sku":"412-0781","price":25.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/10d9bc26097bccba71b817f95924141c.jpg?v=1788827974","url":"https:\/\/voomisupply.com\/products\/osg-412-0781-square-end-mill-5-64-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
