It features a 0.5 inch cutting diameter, a 1 inch length of cut, and a 4-flute spiral geometry with a 30-degree helix angle. The left-hand flute direction paired with a right-hand cutting direction controls chip evacuation and reduces chatter during slotting, profiling, and peripheral milling. This tool is centercutting, allowing plunge entry without a pre-drilled start hole. It is installed by machinists and CNC operators in job shops, production environments, and maintenance machining applications.\u003c\/p\u003e\n\u003cp\u003eThe 447-5000 is suited for use in CNC machining centers and manual mills running ferrous and non-ferrous workpiece materials where an uncoated micrograin carbide substrate provides adequate tool life. The regular-length geometry and 0.5 inch shank diameter are compatible with standard ER and end mill holders. The 3 inch overall length keeps overhang minimal, supporting rigidity in close-tolerance finishing and roughing passes at moderate depths of cut up to the full 1 inch length of cut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with left-hand flute direction for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for applications where bare carbide is preferred\u003c\/li\u003e\n  \u003cli\u003eRegular-length profile minimizes deflection and maintains rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-fitment single-end square end mill with a 0.5 inch straight shank, compatible with ER collet chucks, end mill holders, and set-screw tool holders sized for 0.5 inch shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using appropriate tool holders torqued to machine-tool manufacturer specifications. Ensure the shank is fully seated to the recommended insertion depth before tightening the holder. Confirm spindle runout is within acceptable tolerance prior to cutting, as excessive runout accelerates carbide edge wear. Handle carbide tooling carefully to avoid chipping the cutting edges during setup and storage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: Left 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\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\u003eSeries\u003c\/strong\u003e: 447\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.5 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 447-5000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748311204146,"sku":"447-5000","price":97.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/015c43249a0e487a21c8d2909a7472b4.jpg?v=1788892225","url":"https:\/\/voomisupply.com\/products\/osg-447-5000-square-end-mill-0-5-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
