The Vortex Carbide Chamfer/Countersink Cutter, ALTiN coated and built for precise 90° chamfers, is designed for CNC operators and workshop professionals who demand clean, repeatable edge finishing on aluminum, steel, and other non-ferrous metals. With a compact 4 mm diameter, it delivers consistent results in tight tolerances and busy production runs. Diameter: 4 mm Angle: 90° chamfer/countersink geometry for clean, flush edges Coating: ALTiN coating enhances hardness, lubricity, and heat resistance to extend tool life Material: Solid carbide for rigidity, wear resistance, and precision Applications: Ideal for chamfering and countersinking in aluminium, steel, and other non-ferrous metals Chip Evacuation: Optimized design and coating promote smooth chip flow and cooler cutting This cutter delivers consistent, burr-free edges that improve fit and finish and simplify fastener seating in assemblies. The ALTiN coating helps maintain cutting performance under higher heat, reducing wear across multiple passes, while the carbide core ensures repeatable results even on challenging materials.
