Digga 10 & 11 Series augers: 20-50T

Our 10 & 11 Series augers suit Backhoes, Excavators, large Telehandlers, and machines up to 50t. For efficient drilling, we designed effective auger cutting heads, so depending on ground conditions, you can choose between a tapered cutting head, or rotating rock picks. For extra length, we also have a full range of auger extensions.

Australian made quality

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.

RC10/RC11 earth/rock

Digga’s RC10 & RC11 Augers come with tapered tungsten TAPERLOC teeth, which are designed for drilling in earth, shale, asphalt, permafrost and fracturable rock.

DR11 dedicated 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.
