Auger Torque’s boring heads are designed with a constant spiral cut. Teeth are located so that each makes its own fresh cut on every revolution and are angled to direct spoil towards the centre of the auger. The tooth cutting angle ensures spoil is broken up thoroughly to avoid any clogging.

Replacing worn teeth is simple, just knock out the old pin with a standard hole punch and the tooth will slide out of the holder with ease. You will never need to worry about fitting spare teeth due to losing them again.
