Built from M42 cobalt high-speed steel, it delivers heat and wear resistance that holds up in harder workpiece materials where standard HSS tools fall short. The cutter measures 0.625 inches in diameter with a 1.625-inch length of cut and a 3.75-inch overall length. Its four-flute, right-hand spiral geometry and 30-degree maximum helix angle are configured for efficient chip evacuation during roughing passes. This tool is installed and operated by machinists and tool-and-die professionals on manual or CNC milling machines.\u003c\/p\u003e\u003cp\u003eThe 17010379 is suited for roughing cuts on ferrous and non-ferrous metals in job shop, production machining, and maintenance-repair environments. It carries a bright, uncoated finish and is intended for use without coolant-through capability. The regular-length flute type and non-variable helix design make it a straightforward drop-in for standard roughing applications where a corncob-style chipbreaker profile handles high chip loads efficiently.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e5\/8 inch (0.625 inch) diameter with matching 5\/8 inch shank for concentric fitment\u003c\/li\u003e\n\u003cli\u003e1.625-inch length of cut for moderate-depth roughing passes\u003c\/li\u003e\n\u003cli\u003eSingle-end design, bright\/uncoated finish, no coolant-through requirement\u003c\/li\u003e\n\u003cli\u003eSECO REM445 series for consistent dimensional repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard roughing end mill for use in milling machine collets, end mill holders, and chucks accepting a 0.625-inch straight shank.

Secure the shank fully in a clean, properly sized collet or end mill holder before operation and verify runout before cutting. Confirm spindle speeds and feed rates match the workpiece material and machine specifications before beginning a roughing pass. Do not exceed the rated helix angle or depth-of-cut limits for the holder and machine combination in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.625 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\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\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: 0.25 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: 17010379\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557329273138,"sku":"17010379","price":99.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6439e58b64dd548496520a35a81da33d.jpg?v=1786385816","url":"https:\/\/voomisupply.com\/products\/seco-17010379-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
