DTH drilling tools
Roschen's extensive range of tools for down-the-hole drilling
includes hammers, drill bits and tool systems for simultaneous
drilling-and-casing through difficult overburden. Combining
advanced materials technology with skillful design focusing on
performance, simplicity and endurance, our DTH tools give high
productivity, great reliability and low operating costs.
Features:
1. Valveless air distribution. More reliable.
2. Simple design of the piston. Long life.
3. More efficient energy transfer, fact drilling speed, lower air
consumption and lower oil consumption.
4. Fewer internal parts, simple structure, long life, less failure
and easier to maintain because all the parts are heat treated.
5. Easy to disassemble because the top sub, the drive chuck and the
external cylinder are connected by multi-step thread.
