SD5 Down The Hole Hammer DTH Hammers And Bits For Mining And Quarrying
SD5 down the hole hammer is ideal for use in hard, stable rock drilling applications and overburden drilling applications that require casing systems. Compared to conventional air-powered DTH hammers or top hammers, water-powered DTH hammers offer a wide range of advantages, including low energy consumption, a cleaner environment, minimal hole deviation, deeper drilling capabilities, a high power output ratio and minimal impact on the surrounding ground.
