Vortex Carbide End Mill For Aluminium & Non-Ferrous - 3 Flute Variable Hi Helix -DLC Coated - 4mm x 100mm

The Vortex Carbide End Mill is a professional-grade cutting tool engineered specifically for aluminum and non-ferrous metal machining. With its signature iridescent DLC coating, variable hi-helix design, and 3-flute geometry, this 4mm x 100mm end mill delivers the smooth cuts, superior chip evacuation, and extended tool life that production shops and precision machinists demand.

• Diameter & Length: 4mm diameter with 100mm overall length, providing balanced rigidity and reach for pockets, slots, and contoured parts without excessive deflection
• 3-Flute Variable Hi-Helix Geometry: Three flutes are a performance-enhancing alternative to 2 flute end mills with faster feed rates for aluminum roughing applications. Variable flute spacing reduces vibration and harmonic buildup for cleaner edges and tighter tolerance work
• DLC Coating (Diamond-Like Carbon): DLC coatings are extremely hard with very low coefficient of friction, preventing aluminum from sticking to the cutting edge while providing a mirror-like surface finish. The coating increases wear resistance and extends service life by 2-3 times
• Premium Carbide Substrate: High-quality carbide construction ensures rigidity during high-speed cutting and superior wear resistance compared to high-speed steel (HSS)
• Best-Used Materials: Optimized for aluminum alloys, copper, brass, and other non-ferrous metals where chip sticking and surface finish are critical concerns

The DLC coating minimizes friction and heat buildup, enabling higher cutting speeds in aluminum and soft metals while preventing the built-up edge that degrades tool life and part surface quality. Three flute end mills offer an excellent balance between chip removal and surface finish, especially useful in scenarios where chip evacuation might be a concern but smooth surface finishes are still essential. The variable helix design improves chip evacuation, reducing vibration for consistent performance across production runs and prototyping work alike. This combination reduces tool changes, boosting overall milling efficiency and lowering per-part costs on both roughing and finishing operations.
