Product Description:
DTH drilling is very simple method for the operators for deep and straight hole drilling. In the hole range 100-254 mm (4” ~ 10”), DTH drilling is the dominant drilling method today (especially when the hole depth is greater than 20 meters).
SOLLROC can supply clients full range parts for DTH drilling tools chain, including DTH hammers, bits (or bits equivalent function tools), sub adapters, drill pipes (rods, tubes), RC hammers and bits, dual-wall drill pipes and hammer breakout benches and so on. Our DTH Drilling tools are also well designed and manufactured for mining, water well drilling industries, exploration, construction and civil engineering.

1. Good hole quality, with smooth and even hole walls for easy charging of explosive.
2. Simplicity of operation and maintenance.
3. Good hole cleaning, with plenty of air for the hole cleaning from the hammer.
4. Less amount of drilling fluid and additives are required.
5. Efficient energy transmission and deep hole drilling capacity, with constant penetration and no energy losses in joints through the drill string from start to finish of the hole, as with top hammer.
