"Down The Hole" (DTH) hammers provide the most versatile and cost effective rock drilling method available to date.
Drilling Supply offers an extensive range of DTH hammers suitable for a wide variety of drilling techniques and environments.
1. Advantages of construction method
Use:DTH Hammer drilling is a good way to drill through cave formation and avoid stuck problem
Cave:When encountering caves,drill bit inclines to the cave.The stabilizer ensures the hole straightness
Bit stuck；One reason is cave encounter,the drill bit deviates,and the entire set of drilling tools inclines in the hole.The other,is hole collapse.A large number of rock or clay catch the drill pipe,resulting in bit stuck.Steel casing and stabilizer can resolve this problem.
2. Detailed structure information
DTH hammer series can match to different shank bit like
TH3.5/COP32/DHD3.5/COP34/MACH303/BR33
TH4/DHD340/COP44/MACH44/SD4/QL40
