The cutting edge of the auger has a tapered tip similar to the shape of a Tensiometer or soil water sampler. Thus, the bore hole is large enough to insert the shaft, but the cup will have a tight and perfect fit to the soil.
The not recommendable slurrying of the cup with quartz clay can be avoided.
A divisible auger set includes:
Cutting edge with tapered tip
Handle with hammering head
Parts have threaded connection and can be extended with one or more 100 cm extension rods.
