Built from M42 cobalt high-speed steel and coated with TiCN for added surface hardness and heat resistance, this tool handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. It features a 3\/8 inch mill diameter, 4 flutes in a right-hand spiral configuration, and a maximum helix angle of 30 degrees. The long-series design provides extended reach into deeper pockets and slots. Licensed machinists and tool-and-die professionals use this end mill for roughing passes where chip evacuation and tool life are the primary concerns.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits horizontal and vertical milling machine setups in job shops, production machining, and maintenance environments. The 3\/8 inch shank diameter matches directly to standard ER collet chucks and Weldon-style holders common in both manual and CNC mills. It is appropriate for roughing steel, stainless steel, and similar hard alloys in both prototype and production runs. The 1.5 inch length of cut accommodates moderate-depth slotting and side-milling applications. No coolant-through capability is present, so external flood or mist coolant delivery is standard practice with this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral geometry optimized for roughing passes and high chip loads\u003c\/li\u003e\n  \u003cli\u003e30-degree maximum helix angle balances cutting force and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eLong-series length type extends reach for deeper cavity and pocket work\u003c\/li\u003e\n  \u003cli\u003eSingle-end design — 3\/8 inch shank and 3\/8 inch mill diameter for direct collet or side-lock mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style cutting tool replacement for 3\/8 inch end mill applications in manual and CNC vertical milling machines using standard 3\/8 inch collet or Weldon shank tool holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists following standard toolroom practices. Secure the shank fully into the collet or tool holder, ensuring minimum overhang beyond what the length of cut requires to maximize rigidity and reduce chatter. Power down and lock out the spindle before changing tooling. Do not exceed the tool manufacturer's recommended chip load or surface footage for the workpiece material.\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 (0.375 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: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 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\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: Long Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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: REM445\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 17016193\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559545143602,"sku":"17016193","price":82.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d033c49a1e4282a35ca7af676ae6adbc.jpg?v=1786434996","url":"https:\/\/voomisupply.com\/products\/seco-17016193-roughing-end-mill-3-8-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
