Built from M42 cobalt high-speed steel with a TiCN coating, it delivers heat and wear resistance suited to ferrous and non-ferrous machining. The 0.75-inch mill diameter pairs with a matching 0.75-inch shank diameter, and the long-series geometry provides a 1.625-inch length of cut within a 3.875-inch overall length. Four right-hand spiral flutes with a 30-degree maximum helix angle evacuate chips efficiently while the roughing profile breaks cuts into smaller loads, reducing deflection and extending tool life in heavy-stock removal passes.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual knee mills for roughing operations on steel, stainless, cast iron, and similar materials. The long flute series suits deeper pockets and stepped cavities where additional reach is required. It is a right-hand cutting tool and is not center-cutting, making it appropriate for side milling, slotting, and peripheral roughing rather than plunge entry. Machinists and tool-and-die professionals in job shops, production facilities, and maintenance departments are the typical installers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction resists heat buildup in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and improves surface wear resistance\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes at up to 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eLong-series length of cut (1.625 inches) for deeper pocket access\u003c\/li\u003e\n\u003cli\u003eRoughing geometry reduces cutting forces and minimizes tool deflection\u003c\/li\u003e\n\u003cli\u003eSingle-end design in SECO REM445 series for consistent geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill compatible with standard 3\/4-inch collet chucks, end mill holders, and side-lock holders used in CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove end mills only after the spindle has come to a complete stop and the machine is locked out per applicable safety procedures. Verify holder bore and collet size match the 0.75-inch shank diameter before clamping. Use a torque wrench and follow the toolholder manufacturer specifications when tightening retention hardware. Because this tool is not center-cutting, avoid programming direct axial plunge moves; use a ramping or helical entry strategy instead.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 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: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.875 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\u003eLength Type\u003c\/strong\u003e: Long\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\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: 17016200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563191337266,"sku":"17016200","price":121.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4bb5508d7e6e5aaa6ff523935dcc0f56.jpg?v=1786492633","url":"https:\/\/voomisupply.com\/products\/seco-17016200-roughing-end-mill-3-4-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
