Built from M42 cobalt high-speed steel with a TiN coating, this tool handles tough ferrous and non-ferrous materials while maintaining edge integrity under heat. It features 4 flutes in a right-hand cutting and right-hand flute direction, a 3\/4 inch cutting diameter, and a 3\/4 inch length of cut. The 3\/4 inch shank diameter provides solid tool-holder engagement. Machinists and tool-and-die professionals use this end mill in vertical and horizontal milling machines for hogging stock before finish passes.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for general-purpose milling applications in job shops, production machining, and maintenance environments. The M42 cobalt substrate offers higher heat and wear resistance than standard M2 HSS, making it a practical choice when cutting alloy steels, stainless, and other difficult-to-machine materials. The non-centercutting geometry means plunge cutting is not recommended; use a ramp or helical entry instead. At 3 inches overall length, the tool fits standard short-reach setups with minimal overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand cut geometry optimized for roughing passes\u003c\/li\u003e\n\u003cli\u003e3\/4 inch shank diameter fits common ER and side-lock tool holders\u003c\/li\u003e\n\u003cli\u003eNon-centercutting design — requires ramp or helical entry, not direct plunge\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration for straightforward tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for standard 3\/4 inch ID milling chucks, ER collet systems, and side-lock holders used in vertical and horizontal knee mills and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard tooling procedures. Power down and lock out the machine spindle before seating or removing the tool. Verify holder runout with a dial indicator after clamping to minimize vibration and premature wear.
