Built from M42 cobalt high-speed steel with a TiAlN coating, it delivers elevated heat resistance and extended tool life in ferrous and difficult-to-machine materials. The 3\/8 inch diameter tool features 4 spiral flutes, a right-hand cutting direction, and a 30-degree maximum helix angle. The chipbreaker geometry is absent by design, keeping the profile clean for standard roughing passes. This tool is installed by machinists and tool-and-die professionals in CNC and manual milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing cuts in steel, stainless, and high-temperature alloys where heat buildup and tool wear are primary concerns. The stub length configuration — 1\/2 inch length of cut and 2-1\/4 inch overall length — provides rigidity in short-reach setups, reducing deflection during heavy chip loads. The TiAlN coating supports dry or semi-dry cutting environments. The 3\/8 inch shank diameter matches the mill diameter, making it compatible with standard collet and end mill holders of the same bore size. No coolant-through capability; external coolant or air blast is used at the operator's discretion.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt substrate for elevated red hardness and wear resistance compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating improves oxidation resistance and extends tool life in dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation during roughing passes\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eStub length geometry maximizes rigidity and minimizes deflection in short-reach setups\u003c\/li\u003e\n  \u003cli\u003eSeries REC448 single-end configuration; right-hand flute direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement roughing end mill for use in standard 3\/8 inch collets, end mill holders, and Weldon-style tool holders in CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the holder to the recommended engagement depth per the holder manufacturer's guidelines, and torque set screws or collet nuts per holder specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.003 to -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.062 to -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: REC448\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17007763\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558099386674,"sku":"17007763","price":70.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b11d1a847e98f993550a41e6a272ec49_9f05d670-4eed-4117-849d-1ab9d644a3b4.jpg?v=1786403330","url":"https:\/\/voomisupply.com\/products\/seco-17007763-roughing-end-mill-3-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
