5.0'' QL DHD COP Series DTH Hammers / down the hole hammers

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.
