DTH hammers transmit intensive impact energy with low energy loss. This results in good rock breakage, high penetration rates and high productivity.
There are mainly four types of end face design forms used by down-the-hole drill bits: namely, end face convex type, end face plane type, end face concave type and end face deep concave center type. Cemented carbides are mostly made of ball teeth, spring teeth, or the common tooth distribution method of ball teeth and spring teeth.
