What's included?


Digga A8 Earth Auger Bit
The A8 is a flat tooth auger bit with chisel-ripping teeth on the inner pockets. Ideal for general earth & clay drilling. With multi-facet tungsten teeth fitted, granulated and soft fracturable rock conditions can be drilled.

This auger bit has been designed with a double start single carry flight configuration. Its flight pitch is shallow for greater soil retention, and its heavy-duty shaft allows for greater reliability in tough conditions.

Digga’s True Cut Auger Bits boast a heavy-duty design with high-efficiency cutting heads to maximize your drilling performance. Each Auger Bit is fitted with a range of quality wear parts providing superior wear and performance.

Features

  • Variety of hub options (Hex, Round and Square)
  • Heavy-duty shaft manufactured from high-grade steel
  • Shallow pitch flights for optimum removal of spoil
  • True Cut design ensures a 12” auger drills a 12” hole
  • Full range of drive adapters & extensions available to maximize drilling depth

The angle and geometry of the teeth to the pilot are the key to the unmatched performance unlocked by the A4 series. Available in earth or multi-faced tungsten (MFT) braised onto the face of the teeth, providing longer wear life and greater cutting performance. Not suited to harder fracturable rocks.
