DTH hammers can fit the DTH bits with W shank. Due to its optimized
and robust design, in addition the superior material makes the DTH
hammer longer life, less air consumption and 15% higher penetration
speed than conventional DTH hammer in the market.
Drilling Dia. Range: holes from 90mm to 800mm
Application Fields: Widely used in open pit and underground
mining,Water well drilling.,Deep well,Foundaion,Anchor drilling
Outstanding Advantage:
Piston with swivel grooves to distribute air ensures high drilling
rate
With bush drive sub to distribute air and have a high location to
the bit
Outer Cylinder:Heavy duty cylinder for extended hammer life
