Characteristic：
» Computer analysis and laboratory trials have been used to optimize the number of buttons as well as their size and positioning throughout the bit front.
» Carbide has been carefully designed to minimize the risk of button loss and button failure
» The design of the bit body and the frontal sludge grooves provides uniform flushing with reduces steel wash on both bit and the hammer.
» Material processes and multiple heat treatment have focussed on achieving maximum resistance to fatigue failure.
» Special bit designs such as Concave and Convex/CB are available on request.
