brushes are also available in other dimensions and materials. When ordering spécial sizes please mention full spécification: total length, filling length, filling material, diameter and quantity.
Hole Cleaning Brushes Thèse
brushes have a wooden handle. The model 561.304 has the filling material conically eut. Interior
brushes with zinc coated twisted wire and single spiral. Due to the filling of aluminium oxide or silicon carbide their usage is more flexible than with conven-tional interior
brushes. They are the perfecttoolfor debur-ring of bores, cross bores, o-ring recesses and for polishing and cleaning of small bores. Also
brushes with diamond filament are available. With diamond filament a more aggressive surface of the
brush is reached. *You can only use the
brush with the maximal peripheral speed, when the
brush is inserted fully into the tool. Generally it is the best if the shank sticks out 10 mm when the
brush is mounted and before the
brush starts rotating. 44 LESSMANN
