Extension for mole

The extension rod is an accessory for the Mole hand auger that allows deeper drilling depths to be reached. The rod is 1 m long and is inserted between the T-handle and the auger head. The precisely manufactured connection points prevent wobbling of the auger rod and ensure that the soil core remains securely in the sampling chamber. Even with the extension, the centering and guidance of the Mole remain reliable.

· Increases maximum sampling depth by 100 cm per extension
· Quick assembly/disassembly in the field

Used in geology, agriculture, and environmental analysis for soil investigations when samples are needed from deeper horizons (e.g., for nutrient or contaminant profiles). With the extension, groundwater-near layers can also be sampled without the need for expensive machine drilling – ideal for preliminary surveys. The Mole extension rods make the hand-operated soil auger a flexible tool that can be adapted to each project: leave it out for shallow samples or add as needed for deeper ones – professional, modular, and effective.
