The short auger is bolted onto the end of the drill’s kelly bar to drill dirt and rock for jobs where the drilled shafts will stay open and not collapse.

- Sound wall foundations
- Drilled shafts for foundation piers
- Temporary shoring walls
- Permanent retaining walls
- Bracket pile underpinning
