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.
