Digga RC4 Rock Combo Auger: RC4 rock/combo auger render

About the auger

The Digga RC4 rock combo auger is for ground that mixes earth and rock: earth, shale, asphalt and fracturable rock. It suits excavators up to 5 tonnes, plus mini loaders, skid steer loaders, tractors, telehandlers and truck cranes, on Digga PDD, PDX, PDX2, PDX3 and PD4 drives.

  • 12 diameters from 150 to 600 mm, on a 50.8 mm (2 inch) round or 65 mm round hub. Not every size comes in both hubs.
  • Tapered multi face tungsten teeth for heavy compacted earth, chalky rock and fracturable rock.
  • 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 A4TL, and for hard rock the DR4.

X4 extensions for deeper holes are listed separately. Not sure which hub your drive has? Tell us the drive model and we'll match it before anything is ordered.
