With a 3.8 mm cutting diameter and three right-hand spiral flutes at a 38-degree helix angle, it delivers efficient chip evacuation and consistent cutting performance. The TiAlN coating extends tool life in demanding materials by reducing heat buildup at the cutting edge. The stub-length profile and 5 mm length of cut make it well suited for high-rigidity setups where minimizing deflection is critical. This tool is installed by machinists and CNC programmers working in job shops, tool rooms, and precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is rated for use across a broad range of workpiece materials, including hardened steels, cast irons, stainless steels, general steels, and high-temperature alloys, corresponding to material codes H, K, M, P, and S. The 6 mm Weldon flat shank provides positive drive and accurate tool holding in standard ER or side-lock collet systems. Its center-cutting geometry allows direct plunge entry as well as conventional peripheral and slot milling. The stub-length design keeps overhang minimal, which is especially useful in tight-tolerance finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3.8 mm cutting diameter with a mill diameter tolerance of -0.020 to 0.038 mm for precise fitment\u003c\/li\u003e\n  \u003cli\u003eThree right-hand spiral flutes at 38-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for extended tool life in ferrous and high-temperature alloy applications\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design permits plunge milling and ramping operations\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive rotational drive in side-lock and set-screw holders\u003c\/li\u003e\n  \u003cli\u003eIC900 material grade solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 6 mm Weldon flat tool holders.
