KB drilling buckets are suitable for drilling in water-bearing cohesive and non-cohesive soils, whilst KBF augers are designed for breaking and ripping dense soils up to medium-hard rock. For emptying the bucket, the hinged revolving bottom gate can be opened automatically. A vent tube prevents the creation of a vacuum as the bucket is withdrawn from the borehole.
The drilling buckets are available in a wide variety of configurations:
With flat teeth or round shank chisels
Single or double start type
Different pilot bits
With or without collar ring
Diameter range 520 mm – 2500 mm
