This saves both time and money. Depending on the desired degree of crushing, numerous tooth combinations are available. The various cutter designs, with three to eleven teeth, can be exchanged quickly and easily, thanks to the modular design. You can quickly determine the degree of shredding yourself. The different geometries of the robust cutter cartridges enable the smooth shredding of various solids.
