The Vortex Carbide End Mill is designed for precision aluminum and non-ferrous milling, delivering superior surface finishes and dependable performance at high speeds. Built for rigid setups, its compact 4 mm diameter and 75 mm overall length enable detailed work with repeatable results. Diameter: 4 mm Overall Length: 75 mm Flutes: 3 Geometry: Variable Hi-Helix design reduces vibration and chatter, improves chip evacuation, and supports higher feed rates without sacrificing surface finish Coating: Diamond-like Carbon (DLC) coating with multiple layers minimizes friction and heat at the cutting edge, protects against built-up edge, and enables faster spindle speeds on aluminum Construction: Premium carbide construction delivers exceptional hardness and wear resistance for consistent performance over extended cutting cycles Material Focus: Optimized for non-ferrous materials such as aluminum, brass, and copper, with chip control and surface finish in mind Applications: Ideal for high-speed pocketing, profiling, slotting, and detail work with tight tolerances and clean edges Usage Notes: For optimal results, use with appropriate coolant and ensure your setup remains rigid during continuous milling The combination of 3-flute variable helix and DLC coating reduces cutting forces and thermal stress, delivering smooth, burr-free edges even at higher speeds. The DLC coating lowers friction at the edge, enabling quicker material removal from aluminum while protecting the tool from built-up edge. Built with premium carbide, the end mill maintains sharpness through extended cutting cycles, extending tool life and reducing downtime. Designed specifically for non-ferrous materials, it helps you achieve precise pockets, clean slots, and consistent surface finishes in demanding production runs.
