QL80 COP84 DHD380 M80 SD8 DTH Hammers , High Pressure mining hammer 8.0''
In DTH hammers, the rock drilling bit is a continuation of the
shank, which the rock drill piston strikes directly. Since the
piston is in direct contact with the drill bit, little energy is
lost. This gives DTH hammers a nearly constant penetration rate
regardless of hole length.
