KB21
The all-rounder for ground investigation
The KB21 is the successor to the KB20: the same 54 kW output, but now with exhaust aftertreatment and therefore fully available for the EU market. The trade-off is a larger, heavier design, but it pays off, as the KB21 handles more demanding tasks than its predecessor.
As a result, it has become our best-selling model in recent years. The KB21 is particularly popular for ground investigation work: quick setup, easy operation, and compact dimensions compared to the competition all speak in its favor. It can be used for well drilling, geothermal drilling, ground investigation, and geological exploration.
