The Vortex Carbide End Mill is a precision tool built for machinists and CNC operators milling aluminum and non-ferrous alloys. With a 4 mm diameter, 50 mm reach, DLC-coated carbide construction, and a 3-flute variable hi-helix design, it handles tight pockets and complex contours with consistent results. Diameter: 4 mm Overall Length: 50 mm Flutes: 3 Helix Geometry: Variable hi-helix Coating: Diamond-like Carbon (DLC) Substrate: Premium solid carbide construction Applications: Optimized for aluminum and non-ferrous milling Chip Evacuation: Efficient removal to prevent clogging Cutting Performance: Low friction and heat buildup support higher-speed milling and stable geometry Designed to deliver stable cuts and high-quality surfaces, this end mill reduces downtime and tool changes. The solid carbide substrate provides rigidity and wear resistance, preserving geometry during high-speed aluminum milling. The DLC coating minimizes friction and heat buildup, preventing aluminum from sticking to the edge and often reducing the need for cutting fluids. The 3-flute variable hi-helix geometry minimizes vibration and chatter while promoting aggressive chip evacuation, which is especially important for the sticky nature of aluminum. The 4 mm diameter with a 50 mm reach enables access to tight pockets and extended contours, while its non-ferrous optimization helps prevent chip recutting and built-up edge, ensuring consistent dimensions across production runs. Whether prototyping or running high-volume aluminum work, expect predictable performance, smooth surface finishes, and extended tool life compared with uncoated tools.
