Fitment of the teeth also allows them to be changed in less than two minutes. The teeth fit into slots placed around the wheel and each slot is wedge shaped, as is one side of the tooth. The tooth is held in the slot by a "keeper block" and a single bolt through the top.
The bolt, which is protected against damage, is fastened to a removable nut below the tooth assembly. The wedge shape ensures that teeth are always tight and the design allows for fast removal and replacement of teeth using a small Allen wrench.
The overall result is smooth cutting, less wear on teeth and less stress on the machine. For more details, see www.multi-tip.com.
