Product Overview
High Press Dth Hammer
DTH Hammer has a wide range of use in all kinds of hard and abrasive rocks.
FEATURES AT A GLANCE
It has following advantages:
It has following advantages:
Bit without foot valve will avoid the problem of foot valve broken or thermal expansion
Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher
than the one with foot valve.
Less parts, simplified, and with parts proper heating treated.
Extend the life of using and easier to repairing.
