The Vortex Carbide End Mill is a 2.5 mm diameter, 3-flute square-end milling tool designed for machinists who tackle hard materials. Built for durability and precision, it excels in demanding applications up to HRc55. Diameter: 2.5 mm Flutes: 3-flute design for stability and accurate cuts End geometry: Square end for perpendicular, clean bottoms Material: Carbide for enhanced hardness and wear resistance Hardness compatibility: Suitable for materials up to HRc55 Chip evacuation: Efficient chip removal to reduce heat and improve surface finish Applications: Ideal for high-precision milling and demanding, challenging milling tasks With its 3-flute design and carbide core, this end mill provides consistent cutting action, tighter tolerances, and smoother finishes on hardened workpieces. The square cut enables precise slotting and profiling, while the robust construction stands up to repeated passes in HRc55 material. Expect longer tool life, lower cycle times, and fewer tool changes in tough milling jobs, thanks to efficient chip clearance and stable cutting.
