The axial and radial forces that occur during countersinking operations are greatly reduced due to the newly developed geometry of the SpyroTec cutting edges. Due to convex different radii of the cutting edges with variable helical pitch provide a stable and low-vibration countersinking process. The specially designed TiAlN coating ensures a higher wear resistance and high-temperature hardness which guarantee longer tool life of nearly all materials and applications.
