TH----for wet drilling
Wadely applied to all kinds of rock boring hole drilling and excellent in projects for casing system and water well drilling.
Can be matched to various types of hammers popular in the world and drill the holes from 76mm to 1200mm in diameter.
TS----for deep hole and super deep hole drilling
Can be meet to the needs of drilling holes from 203mm to 660mm in diameters.
TG----for drying drilling
Have stable performance, fast speed, long service life in sleeves, and 10% less air consumption than other ordinary hammers, and can also work well without the foot valves.
Drill holes from 90mm to 254mm.
All our Hammers can be easily adapted to accept different types of bit shanks as COP, BR, DHD, SD, XL QL, MACH, Halco and Mission by simply changing a few basic components. Several models are available in Heavy-Duty format to suit particularly arduous and abrasive drilling conditions.
DTH hammer is one of our main products.It strictly matches with API standard and other Chinese industry standards.It is durable for being produced with advanced craftwork and good material.It also has the following advantages:
First,Can be used in hard rock application.
Second,it Can work on low to high pressure radius.
Third,High rate of penetration while utilizing less air.
