Built from M42 cobalt high-speed steel with a TiCN coating, it handles tough workpiece materials while maintaining edge integrity under heat. The 1\/2-inch diameter cutter features 4 right-hand spiral flutes with a 30-degree maximum helix angle, a 1.25-inch length of cut, and a 3.25-inch overall length. The shank diameter matches the cutting diameter at 1\/2 inch, making tool holding straightforward with standard collets or end mill holders. This tool is center-cutting and designed for right-hand cutting direction.\u003c\/p\u003e\u003cp\u003eThe 17016585 is suited for roughing passes on ferrous and high-temperature alloy workpieces in job shop and production machining environments. The TiCN coating improves surface hardness and reduces friction, extending tool life in interrupted cuts and slotting operations. The Series REC700 designation places it in a recognized roughing geometry family. This end mill does not include coolant-through capability, extended reach, variable helix, variable index, or a chipbreaker profile. It is intended for machinists and tool-and-die tradespeople working on manual or CNC vertical milling machines and machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends edge life in tough materials\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry\u003c\/li\u003e\n\u003cli\u003e1\/2-inch shank diameter compatible with standard collets and end mill holders\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration; Series REC700 roughing geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-procurement roughing end mill for standard 1\/2-inch tooling systems on vertical milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following shop safety procedures. Power down and lock out the spindle before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention mechanism to the machine or holder manufacturer specification. Verify runout with a dial indicator before beginning a cut. Do not exceed the rated depth of cut for the flute length indicated.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\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: 1.2500 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: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eCenter-Cutting\u003c\/strong\u003e: Yes\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: REC700\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\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: 17016585\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557813846322,"sku":"17016585","price":105.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75034769c6bcafee62465e34d1cfb3f7_bd8eba05-6347-4898-b0eb-891ec753e8c4.jpg?v=1786395913","url":"https:\/\/voomisupply.com\/products\/seco-17016585-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
