About the auger

The Digga RC8 rock combo auger drills ground that mixes earth and rock, from heavy compacted earth through shale and asphalt to fracturable rock. It suits 10 to 20 tonne excavators and backhoes, on Digga drives from the PD10 to the PD22.

  • 15 diameters from 150 to 1,500 mm, all on a 75 mm square hub.
  • Tapered multi face tungsten teeth, 10 mm flights and a 1,500 mm overall length.
  • A 300 mm auger drills a true 300 mm hole, and the teeth knock in and out with no special tools.
  • Australian made. For earth only see the A8, and for hard rock the DR8.

XO75HD and XT75HD extensions for deeper holes are listed separately. Tell us your drive model when you order and we'll check the auger suits it before anything is ordered.
