Sampler Mole / Bürkle

The soil sampler made from iron consists of 3 parts: a handle with rod, optional extensions and the hardened drill bits. For determining soil properties, moisture
and structure. Extension rods can extend the working depth of the Mole down to 5 m. Individually customisable.

Drill bits for different soil properties:
Clay and damp soil: With narrow side panels for minimum soil friction/resistance. The soil adheres to the bit very well
Sand: With broad side panels and therefore a large retention capacity for the sand
Coarse sand: With extra broad side panels for sampling sandy soils and very dry soils
Combination: Retains both strongly cohesive and less cohesive soils
Riverside: Very suitable for drilling in hard, encrusted soils and soils mixed with fine gravel. The drill cutters project from the drill itself, so that friction is greatly reduced
Gravel drill: With slightly rounded, oblique scoops. Any stones present are clamped between the drill sides.
Stone catcher: The stone catcher is used to collect and remove stones that prevent proper sampling
