Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers the heat and wear resistance needed for cutting harder ferrous and non-ferrous materials. The 3-flute geometry with a high helix angle and right-hand cutting and flute direction promotes efficient chip evacuation and reduces vibration during roughing passes. At 0.375 inches in diameter with a 0.75 inch length of cut and a 2.5 inch overall length, this tool fits standard 3\/8 inch collet or end mill holders. It is center-cutting, allowing plunge entry into workpieces.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations on a CNC machining center or manual knee mill where fast stock removal is the priority. The cobalt M42 grade construction makes it a practical choice when cutting alloy steels, tool steels, stainless steel, and similar tough materials at elevated spindle speeds. The single-end configuration is standard for general shop use and toolroom work. Machinists and tool-and-die technicians typically use this style of roughing mill before transitioning to a finish end mill to bring parts to final dimension.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction provides elevated heat and wear resistance compared to standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e3-flute high-helix design promotes rapid chip evacuation during heavy roughing cuts\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without pre-drilled starting holes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for use in conventional spindle setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains sharp edge geometry out of the box\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter matches standard collet and end mill holder sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for any milling machine or machining center equipped with a 3\/8 inch collet, end mill holder, or Weldon-style tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine powered off and the spindle fully stopped.
