Built from M42 cobalt high-speed steel, it delivers hardness and heat resistance suited to cutting ferrous metals and tough alloys. The 5\/8 inch diameter cutter carries four right-hand spiral flutes with a 30-degree maximum helix angle, producing a shearing action that reduces cutting forces and improves chip evacuation. Overall length is 3-3\/8 inches with a 1-1\/4 inch length of cut. The bright, uncoated finish is standard for cobalt tooling used in general-purpose roughing work. This tool is installed and operated by machinists and tool-and-die professionals on conventional or CNC milling machines.\u003c\/p\u003e\u003cp\u003eThe 17010849 is suited for roughing passes on ferrous metals, stainless steels, and heat-resistant alloys where material removal rate is the priority over surface finish. The short flute length and rigid 5\/8 inch shank minimize deflection during heavy cuts. It is not center-cutting, so it requires a pre-drilled entry point or ramp entry when cutting enclosed pockets. The Series REM445 designation places this tool in SECO's roughing end mill family intended for shop-floor roughing and semi-finishing operations on manual and CNC milling equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e5\/8 inch diameter with matching 5\/8 inch shank for balanced rigidity\u003c\/li\u003e\n\u003cli\u003e1-1\/4 inch length of cut in a short overall length of 3-3\/8 inches to minimize overhang\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — compatible with common cutting fluids and oils\u003c\/li\u003e\n\u003cli\u003eNot center-cutting — requires pre-drilled or ramped entry into closed pockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill replacement for milling machine spindles accepting a 5\/8 inch straight shank, consistent with Series REM445 tooling specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by machinists using a standard end mill holder or collet chuck rated for the 5\/8 inch shank diameter. Confirm the shank tolerance (-0.0001 to -0.0005 inches) is within the acceptable range of your toolholder before mounting. Because this tool is not center-cutting, do not plunge directly into solid material — use a pre-drilled hole or a programmed ramp entry. De-energize the machine spindle and lock out power before changing tooling per applicable machine safety procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.6250 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: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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: 0.09 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: 17010849\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557352407346,"sku":"17010849","price":97.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9.jpg?v=1786386203","url":"https:\/\/voomisupply.com\/products\/seco-17010849-roughing-end-mill-5-8-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
