Built from solid carbide with an AlTiN coating, this tool delivers hardness and heat resistance suited for cutting ferrous metals and hardened steels. It measures 3\/8 inch in diameter with a 1\/2 inch length of cut and a 2 inch overall length. The 4-flute, fine-pitch spiral geometry combined with a 20-degree maximum helix angle helps manage chip evacuation while maintaining cut stability. The 3\/8 inch Weldon flat shank provides secure tool holding in standard end mill holders. Licensed machinists and CNC operators working in job shops or production environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis roughing end mill fits milling operations on machining centers and manual mills where high material removal rates are required before finishing passes. The fine pitch and right-hand cutting direction make it suitable for slotting, profiling, and roughing passes in ferrous and hardened workpiece materials. The AlTiN coating supports dry or minimal-lubrication cutting environments by reducing heat buildup at the cutting edge. This is a regular-length tool appropriate for standard reach applications where extended reach is not needed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e4-flute fine-pitch spiral geometry optimized for high material removal rates\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank ensures positive engagement in end mill holders\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application tool for standard 3\/8 inch end mill holders using a Weldon flat shank interface on vertical machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to prevent axial pullout. Verify runout with a dial indicator before commencing cuts, as excessive runout will accelerate tool wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 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: 0.5000 inches\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: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle (Maximum)\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0200 inches\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\u003eCenter Cutting\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SR420\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 to -0.060 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 17004666\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557318361394,"sku":"17004666","price":129.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ee5ed1c6e160dfb312dd0a3f2a5ccad.jpg?v=1786385719","url":"https:\/\/voomisupply.com\/products\/seco-17004666-roughing-end-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
