Meet the Vortex Carbide End Mill — a purpose-built tool for aluminium and other non-ferrous metals. With a long length and 3-flute, square-edge design, it’s optimized for deep pockets, slots, and extended reach without sacrificing finish. Diameter: 4 mm Overall Length: 75 mm Flutes: 3 End Geometry: Square edge for flat bottoms and precise pockets Material: Solid carbide for stiffness and wear resistance Helix Angle: 55° to facilitate chip evacuation and reduce cutting forces Material Suitability: Effective on aluminium and non-ferrous metals The 3-flute, long-reach design excels in deep milling tasks where standard-length tools struggle. The 55° helix promotes aggressive chip evacuation, helping maintain a clean cut and preventing built-up edge on soft metals. Carbide rigidity delivers consistency and long tool life, while the square edge yields precise, square-bottom pockets and accurate finishing in pockets, slots, and contours. This end mill is ideal for workshop machinists and production environments that require reliable performance in aluminium and non-ferrous alloys, with predictable results across multiple passes and feeds.
