DTH Button Bit DHD350 with Dia140mm,Concave or Convex face in 5'' High Air Pressure
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.
