4 Flute T-Slot Carbide End Mill TiSiN HRC 55

4 Flute T-Slot Carbide End Mill for Aluminum and Non-Ferrous Material Machining

The 4 Flute T-Slot Carbide End Mill is specifically engineered for precision CNC machining of T-slots, undercut grooves, keyways, and complex profile features in aluminum alloys, copper alloys, plastics, and other non-ferrous materials. Manufactured from premium ultra-fine grain solid carbide and enhanced with a wear-resistant TiSiN coating, this cutter provides excellent rigidity, cutting stability, and extended tool life in demanding machining environments.

Designed with a precision-ground T-slot cutting profile, the tool enables efficient machining of T-shaped grooves and undercut features that cannot be produced using conventional square end mills. The optimized 4-flute geometry delivers smooth chip evacuation, reduced vibration, and improved surface finish, making it an ideal solution for precision mold components, machine tables, fixture plates, aluminum structural parts, and custom CNC-machined components.

The reinforced cutter head provides exceptional strength during side cutting and slot forming operations, allowing stable machining performance even in deeper grooves and long production runs. Whether used for roughing, semi-finishing, or finishing applications, this T-slot cutter ensures excellent dimensional accuracy and repeatability.
