Depending on ground conditions, you can choose a bladed or tapered cutting head, or rotating rock picks. For deeper holes, a full range of auger extensions are available for your specific requirement.
With over 30 years of auger design and manufacturing using the highest quality material, Digga augers boast extremely efficient cutting head designs, heavy duty tubing, and optimum flight pitches to provide maximum spoil removal in all ground conditions.
Digga's RC4 Augers come with tapered tungsten TAPERLOC teeth, which are designed for drilling in earth, shale, asphalt, permafrost and fracturable rock.
DR augers feature rotating rock picks for drilling from soft fracturable rock to very hard rock. Featuring short flighting, the design encourages regular spoil removal, allowing cool air to enter the hole, and facilitate regular tooth inspection. Watch our rock auger overview video.
