Product information "Bürkle, Mole Drill Bit, Riverside, #5350-1035"
Various drill heads are available for the Maulwurf, each designed for very specific soil conditions:
Clay and damp soils
With narrow flanks that cause the least friction/resistance in the soil. As damp soils are generally highly cohesive, the soil still adheres well to the auger.
Sand
With wide flanks, providing a larger contact surface area in which the sand can grip firmly.
Coarse sand
With extra-wide flanks that close the auger even more tightly, thereby holding coarse sand soils or very dry soils firmly in place.
Combination
Holds both highly cohesive and less cohesive soils.
Riverside
Highly suitable for drilling in hard, encrusted soils and soils mixed with fine gravel. The drill blades extend beyond the core drill, thereby significantly minimising friction.
Gravel auger
Features slightly curved, angled blades that pull themselves downwards through the gravel. Any stones are trapped between the drill flanks. The finer soil material (coarse sand with fine gravel) is retained inside the drill.
Stone catcher
The stone catcher can be used to catch and extract stones that prevent smooth sampling with any of the drill heads.
Sterility: No
