Built from solid carbide with an AlTiN coating, it delivers heat resistance and extended tool life at elevated cutting speeds. The 3\/8-inch diameter cutter features 4 flutes in a right-hand spiral configuration with a fine pitch and a 20-degree maximum helix angle. The 45-degree chamfer angle and 0.0200-inch chamfer width contribute to controlled chip formation. With a 1-inch length of cut and 2.5-inch overall length, this end mill suits compact workholding setups and tight-clearance applications where rigidity and precision matter.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where roughing passes demand consistent chip evacuation and tool stability. The Weldon flat shank provides positive drive and minimizes pullout risk under heavy side loads. The AlTiN coating makes it well-suited for cutting ferrous materials, hardened steels, and high-temperature alloys. Machinists and toolroom technicians working in job shops, production facilities, and tool and die environments will find this tool appropriate for slot milling, peripheral roughing, and step milling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard material applications\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-heat resistance and extended tool life in dry or minimal-lubrication cutting\u003c\/li\u003e\n  \u003cli\u003e4-flute fine-pitch spiral design promotes efficient chip evacuation during roughing passes\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank reduces tool pullout risk under high side-load conditions\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide roughing end mill suitable for use in standard 3\/8-inch collet chucks and Weldon flat tool holders on CNC machining centers and knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Secure the Weldon flat shank in a properly sized end mill holder and torque the set screw to the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning the cut. Always power down the spindle and confirm the machine is in a safe state before changing tooling.\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 inches (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\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\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 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: 0.13 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: 17004667\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557332091186,"sku":"17004667","price":149.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc4557bc21b05c472d33bbcdc6bc0a60.jpg?v=1786385853","url":"https:\/\/voomisupply.com\/products\/seco-17004667-roughing-end-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
