4 series augers - up to 5t
Our 4 Series augers are specially designed for mini loaders, skid steer loaders, and excavators up to 5 tonnes. For efficient drilling, the key is an effective auger cutting head. Depending on the ground condition, you can choose between a bladed cutting head, a tapered cutting head, or a rotating rock pick design. Need to drill deeper? Digga has a full range of auger extensions available to suit your specific requirements. Digga Augers come complete with Easy PADLOC knock in and out teeth which require no special tools.
A4 earth
the A4 is the Contractor's choice able to drill holes in earth and clay and designed specifically for the tough Australian conditions. Available in Earth and Multi Faceted Tungsten (MFT) for general drilling.

Digga's RC4 Augers come with tapered tungsten TAPERLOC teeth, which are designed for drilling in earth, shale, asphalt, permafrost and fracturable rock.
