GG-VS-CAST IRON ADI+
Cast iron tapping
GG taps are made of high-speed PM steel with low cuting angles, which combined with accentuated back ridges, make this type of tap suitable for machining abrasive materials such as CAST IRONS. They have an extra tolerance (6HX) and a TiAlN coating additionallu to a surface micro-finish. On request, they can be supplied with a short E-chamfer (1.5 - 2 x P) for tapping with a reduced exhaust chamber. News, besides 25° worm taps are available for application on ferrous cast irons (steel castings).
