    High Air Pressure 4"DTH Hammers and bits SD4/QL40/DHD340/M40 for mining and water well
     

    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.

    Applications

     
    • Underground mining
    • Down the hole rock drilling

     

    Competitive Advantage
     

    •  Valveless air distribution, more reliable.

    •  Simple design of the piston. Long life span.

    •  More efficient energy transfer, faster drilling speed, low air consumption and lower oil consumption. 

    •  Fewer internal parts, simple structure, less failure and easier to maintain.

    •  Easy to disassembled because the top sub, the drive chuck and the external cylinder are connected by       multiple steps thread.
