Built from M42 cobalt high-speed steel with a TiCN coating, it handles tough interrupted cuts and high-heat environments better than standard HSS tooling. The mill measures 0.625 inches in diameter with a 1.625-inch length of cut and a 3.75-inch overall length. A 30-degree maximum helix angle and right-hand spiral flute geometry promote chip evacuation during heavy roughing passes. This tool is installed by machinists and CNC operators working in job shops, toolrooms, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations on alloy steels, tool steels, stainless steel, and similar hard materials where heat buildup and tool wear are primary concerns. The TiCN coating adds surface hardness and lubricity, reducing friction and extending tool life compared to uncoated cobalt tooling. The 5\/8-inch shank fits standard collets, end mill holders, and milling chucks used on vertical mills, knee mills, and CNC machining centers. It is a non-centercutting design intended for peripheral and side milling rather than plunge cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved red hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in hard material applications\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with chipbreaker geometry for efficient chip clearance during heavy cuts\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle supports aggressive roughing passes\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 0.625-inch shank diameter for standard toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eSeries REM445 geometry optimized for roughing stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 5\/8-inch end mill holders, collet chucks, and milling chucks on vertical mills, knee mills, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists and CNC operators. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a torque wrench and the appropriate collet or end mill holder to secure the shank; do not overtighten set screws against the shank diameter. This is a non-centercutting tool — do not use for direct plunge operations. Verify tool runout with a dial indicator after installation before beginning a cut.\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: 0.6250 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 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\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: 0.6250 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\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\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: 0.3 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: 17016198\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563915903282,"sku":"17016198","price":108.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_1849a48a-4bdd-41ec-b15e-ab8934c2cb5f.jpg?v=1786506737","url":"https:\/\/voomisupply.com\/products\/seco-17016198-roughing-end-mill-5-8-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
