A typical cutting head would have 12 or more cutting teeth (in pairs, in pockets) compared to 6 or 8 teeth on a MULTI-TIP wheel.
A single M10 ‘hex head’ bolt is then passed through the keeper block into a threaded insert under the tooth assembly. The bolt does not require high tension, since the forces are taken through the wheel, not the tooth.
All that is needed to change a tooth is an 8mm allen key. No chocking the wheel. No breaker bars!
The whole tooth assembly can be removed in under 30 seconds.
The wheel slot is wedge shaped so that the angled tooth is drawn down into the slot using the keeper block. This ensures the tooth is always held rigidly in place.
