Built from M42 cobalt high-speed steel and finished with a TiCN coating, it handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 1\/4 inch cutting diameter pairs with a 3\/8 inch shank, a 5\/8 inch length of cut, and a 2-7\/16 inch overall length. Four spiral flutes cut in the right-hand direction with a 30-degree maximum helix angle, promoting efficient chip evacuation during heavy roughing passes. This tool is part of the REM445 series and is suited for manual and CNC machining centers used by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis end mill is applied in roughing operations on milling machines and CNC machining centers where stock needs to be removed quickly before finishing passes. It is not center-cutting, so it requires a pre-drilled entry point or a ramping move when plunging. The TiCN coating extends tool life in abrasive and hardened materials. Typical applications include slotting, profiling, and peripheral milling in ferrous metals, stainless steels, and high-temperature alloys where M42 cobalt provides added hot hardness over standard M2 tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved hot hardness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating extends tool life in abrasive and hardened materials\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch shank diameter provides secure clamping in collet or end mill holders\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration — REM445 series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard collet chucks, end mill holders, and side-lock holders accepting a 3\/8 inch shank diameter on manual knee mills and CNC vertical machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tooling technician. Power down and lock out the spindle before changing tooling. Seat the 3\/8 inch shank fully and evenly in the holder before tightening to manufacturer torque specifications for the holder type in use. This end mill is not center-cutting — do not use it for direct plunge drilling without a pre-drilled entry point or a programmed ramp entry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\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: 17016188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560187920690,"sku":"17016188","price":75.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bab660b555393fd7888d08301ba0d873.jpg?v=1786448683","url":"https:\/\/voomisupply.com\/products\/seco-17016188-roughing-end-mill-1-4-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
