Built from M42 cobalt high-speed steel, it delivers heat and wear resistance where standard HSS tools fall short. The tool features a 3\/4-inch mill diameter, a 3-inch length of cut, and a 5-1\/4-inch overall length. The bright, uncoated finish is suited for applications where coating is not required or where re-sharpening is anticipated. Right-hand cutting and right-hand flute direction are standard. This tool is installed and used by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is intended for use in milling operations on ferrous and non-ferrous metals where high material removal rates are the priority. The 4-flute, spiral-flute geometry with a 30-degree maximum helix angle and chipbreaker-style roughing profile reduces cutting forces and manages chip evacuation in slotting, peripheral milling, and roughing passes. It is not center-cutting, making it appropriate for side milling and peripheral roughing rather than plunge cuts. The 3\/4-inch shank diameter matches the mill diameter for straightforward toolholder setup in standard end mill holders and collet chucks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat resistance and tool life in harder materials\u003c\/li\u003e\n\u003cli\u003e3\/4-inch mill diameter with matching 3\/4-inch shank diameter for balanced toolholder fit\u003c\/li\u003e\n\u003cli\u003e3-inch length of cut suitable for deep roughing passes\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — compatible with re-sharpening and general-purpose roughing\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute, single-end design in regular length series REM710\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style single-end roughing end mill for use in standard 3\/4-inch end mill holders, milling chucks, and collet-style toolholders on vertical and horizontal milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists and CNC operators using standard end mill holders or collet chucks sized for a 3\/4-inch shank. Ensure the machine spindle is fully stopped and locked out before installing or removing the tool. Verify shank seating depth and holder runout before beginning a cut.
