Built from M42 cobalt high-speed steel and finished with a TiCN coating, it delivers the hardness and heat resistance needed for cutting tough ferrous and non-ferrous materials. The 3\/4 inch diameter tool features 4 spiral flutes with a right-hand cutting and flute direction, a 30-degree maximum helix angle, and a 2 inch length of cut. At 4.25 inches overall length, it fits standard milling machine spindles and CNC machining centers. This tool is installed and maintained by machinists and toolroom professionals working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for roughing passes in milling operations where rapid stock removal is the priority. The REM710 series profile is intended for use in conventional and CNC vertical milling setups. The 3\/4 inch shank diameter matches the tool diameter, making it compatible with standard ER collets and end mill holders of that size. It is not center-cutting, so it should not be used for direct plunge operations. The TiCN coating provides added wear resistance and reduced friction during high-feed cutting passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for hardness and thermal resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces wear and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling setups\u003c\/li\u003e\n\u003cli\u003e3\/4 inch shank diameter with tight tolerance (-0.0001 to -0.0005 inches) for secure tool holding\u003c\/li\u003e\n\u003cli\u003eRegular length designation at 4.25 inches OAL for use in standard tool holders without extended reach\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement roughing end mill for use in standard milling machines and CNC machining centers accepting 3\/4 inch end mill holders or ER collet systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before changing tooling. Secure the shank fully in the collet or end mill holder to the manufacturer-specified engagement depth before tightening. Do not use this tool for plunge cuts, as it is not center-cutting. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds based on workpiece material.\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\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle (Maximum)\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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt HSS (M42)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: REM710\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: 17015187\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557527159090,"sku":"17015187","price":141.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2596842e80fb9af8fb7e1eaf26509c2a.jpg?v=1786390164","url":"https:\/\/voomisupply.com\/products\/seco-17015187-roughing-end-mill-3-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
