Built from micrograin solid carbide and coated with TiAlN, it handles high-heat cutting conditions common in hardened steels, stainless, and alloy materials. The 3 mm cutting diameter pairs with a 6 mm shank, making it suited for close-tolerance work in die and mold, aerospace component machining, and general metalworking. With 4 right-hand spiral flutes and a centercutting design, it supports both plunge and peripheral cuts. Licensed machinists and CNC operators install this tool in standard end mill holders or collet chucks.\u003c\/p\u003e\n\u003cp\u003eThe HP400-1181 is intended for precision milling applications where a small-diameter roughing tool is required. The 10 mm length of cut and 64 mm overall length make it appropriate for shallow-to-moderate depth passes in tight cavities or profiling operations. Its regular-length geometry fits standard CNC machining center setups. The right-hand cutting and flute direction are consistent with conventional milling machine spindle configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3 mm cutting diameter with 0.1181 inch decimal equivalent for cross-reference\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life in high-temperature cutting environments\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes for efficient chip evacuation during roughing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003e6 mm shank diameter fits standard collet and end mill holder tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for CNC machining centers and manual mills equipped with ER collet chucks or end mill holders accepting a 6 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is properly seated to the minimum recommended gauge length before torquing the holder. Verify runout with a dial indicator before beginning cuts. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when handling carbide cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3 mm (0.1181 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: 10 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 64 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 0.2 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: HP400-1181\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730121654578,"sku":"HP400-1181","price":62.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c0bfafc15f38475e0adad876add4c871.jpg?v=1788712067","url":"https:\/\/voomisupply.com\/products\/osg-hp400-1181-roughing-end-mill-3mm-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
