4 Inch High Air Pressure DTH Hammer for DHD340A Shank With Foot Valve 
 

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.
