The blades of this auger bit are slightly broader and rounder than those of the clay type, permitting a good hold of moderately cohesive soils, while cohesive soils can easily be removed. The bit is elongated allowing easy augering in stiffer soil.
Available in several diameters from 4 cm to 10 cm
They are used with Eijkelkamp bayonet type T-handles and extensions which are sold separately.
