For optimum adaptation to various soil conditions, the GRUNDOMAT soil displacement hammers can be equipped with movable crowned or stepped heads. Both versions operate with equal precision, stability and efficiency, each in their own way.
Our users appreciate the crowned head especially in loose, stony and densely packed soils, thanks to its aggressiveness and enormous penetration force in hard ground conditions. Experienced drilling professionals are of the opinion: "This head lets nothing hold it back in achieving its goal".
The stepped head, which has been tried and tested for decades, is universally applicable in all displaceable soils and is the "classic" among the soil displacement hammers.
