The breaker hammers are an excellent low-cost tool for taking soil samples. They provide high impact energy to drive the soil sampling tubes quickly into the ground. All hammers though have their own specific tool retainer; this implies that cross-overs are required in order to attach the DPT sounding rods.
Gouda-Geo supplies insert hammer heads for the most common breaker hammers on the market today. They are easy to use and fit directly into the tool retainer of the hammer. Made of high quality steel assuring longevity.
