12.0 INCH DHD1120 High Pressure DTH down hole hammer / rock hammer
12.0 INCH DHD1120 High Pressure DTH down hole hammer / rock hammer
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.
