The Vortex ALTiN-coated 90° chamfer/countersink cutter is built for precise edge finishing in metalworking. Designed for professional machinists and DIY enthusiasts alike, it delivers clean, repeatable chamfers and countersinks with extended tool life. Shank Diameter: 12 mm Angle: 90° chamfer/countersink angle for accurate entry and finishing Coating: ALTiN coating boosts hardness, lubricity, and heat resistance Material: Solid carbide construction for rigidity and long life Applications: Suitable for aluminium, steel, and other non-ferrous metals Chip Evacuation: Optimized geometry and coating promote smooth chip flow and reduced heat buildup With its robust carbide core and ALTiN finish, this cutter delivers crisp, repeatable chamfers and countersinks, helping you achieve professional surface finishes and precise deburring. The 90° angle is ideal for edge finishing, hole deburring, and accurate part assembly, minimizing the need for secondary operations. The ALTiN coating enhances wear resistance, extending tool life in demanding cutting conditions, while reducing friction for smoother cuts. This makes the Vortex cutter a dependable choice for shops and makers working with aluminium and other non-ferrous metals, as well as certain steels, where consistent performance matters most.
