Part of the SECO JS413 series, this single-end mill features a 0.3937 inch cutting diameter, a 1.5748 inch length of cut, and a 3-flute spiral geometry with a 40-degree helix angle. The right-hand cut, right-hand flute configuration delivers efficient chip evacuation and stable cutting action. Micrograin carbide construction provides edge retention in demanding machining environments. This tool is intended for use by machinists and CNC operators working in production or job shop settings.\u003c\/p\u003e\u003cp\u003eThe 02881817 is suited for milling non-ferrous metals such as aluminum, brass, and copper alloys where a high-helix, centercutting end mill is preferred. The extended length-of-cut design supports deeper slotting and profiling passes without requiring a tool change. The straight-cylindrical shank with h5 tolerance ensures consistent runout in standard collet and end mill holders. This tool fits the extended length classification and is appropriate for applications where standard-length reach is insufficient.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.3937 inch cutting diameter with e8 tolerance for precise fit and finish\u003c\/li\u003e\n\u003cli\u003e1.5748 inch length of cut supports deep slotting and full-depth profiling\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry with 40-degree helix angle optimized for non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and wear resistance\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for aluminum and other non-ferrous applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement end mill for use in CNC machining centers and manual mills accepting a 0.3937 inch straight-cylindrical shank.
