WBM Casing Hammer

Weldco-Beales air driven Casing Hammers can be fitted to most standard rotary top drive drilling rigs. The drill thru feature of our design means the casing can be driven while drilling progresses. The operator can precisely control the energy output of the hammer and vary the number of blows per minute to adjust to the geological formations encountered. A single mechanical valve controls the air distribution which results in fewer problems. A simple adjustment to the Casing Hammer and removal of top anvil collar will allow up-driving for casing withdrawal.
