A6 Earth Auger Bits
Digga's auger bit range has been designed from over 35 years of manufacturing and designing experience for the ultimate in performance, quality and cost effectiveness. With the A6 range, you benefit from its 1 3/4 hex drive pilot over the square drive - giving machines with higher down pressure and higher torque greater strength. The A6 suits Skid Steers and Excavators up to 8 tons for drilling in earth.
The A6 is a flat tooth auger bit with chisel ripping teeth on inner pockets. Ideal for general earth & clay drilling. With multi facet tungsten teeth fitted, granulated and soft fracturable rock conditions can be drilled. This auger has been designed with a double start single carry flight configuration. Its flight pitch is shallow for greater soil retention, and its heavy duty body allows for greater reliability in tough conditions.

RC6 Combination Earth & Rock Auger Bits
RC6 auger bits are available with a range of different teeth options to suit most ground conditions including earth, hard soils, shale, clay, and permafrost.
Basically, with the RC6, you get all the benefits of the A6 plus the superior penetrating ability of the B7 taper tooth head. The RC6 comes complete with all purpose taper teeth perfect for combination drilling in all conditions - from earth to medium rock, providing a clean hole every time.
RC6 teeth are easy to install and remove with Digga's ingenious knock in, knock out tooth locking systems which eliminates the need to use extra tools to remove the teeth.

DR6 - Dedicated Rock Auger Bits
Digga’s DR6 auger bits feature rotating rock picks and are specially designed for drilling from soft fracturable rock to very hard rock.
DR6 auger bits also feature short flighting to encourage regular spoil removal, allowing cool air to enter the hole and facilitate regular inspection of its carbide bullet teeth.
For
smaller holes, or smaller drilling drives, Digga has made available DR4 auger bits. For larger diameter holes or larger drilling drives, DR11 auger bits are also available.
