The PREMIUM tube brushes from Tyrolit are characterized by the simplest handling and universal applicability. The galvanized rotating wire and the simple fill spiral make polishing or cleaning of complex workpieces, such as nozzles, much easier. This tool can be used hand-held / freehand / hand-guided as well as on drilling machines, taking into account the max. permissible speed, and delivers the best surface results. The abrasive bristles are also effective on the sides to achieve edge rounding at bore transitions.
