RC(Reverse Circulation) Hammers

Our products are widely used in open-pit or underground mining, hydraulic engineering, bridge engineering, construction engineering, geotechnical engineering.

Oil gas drilling and other field. Our main products include DTH (down-the-hole) hammers and bits with capacity of drilling holes from 64mm–1020mm in diameter, DTH drilling tools with large diameter for deep hole drilling, eccentric casing system (ODEX) and concentric casing system, reserve circulation hammers and bits, drilling rig, rock drilling accessories and other relative equipment. With strong technical strength, we are making effort to create the best brand of Chinese drilling tools, and to be the top manufacturer in the world.

Advantages
Accurate sampling;
Environmental operation;
Compared with conventional drilling tools, RC tools flush cuttings inside the pipe with small resistance to effect easy flushing;
Special custom made alloy steel is adopted for sampling tube and shroud, and the surface of flushing pipe is hardened;
Good quality sealing rings are selected as follows:Reverse Circulation Drilling Tools

A drilling system that flushes cuttings out from inside the pipe; Low air consumption; Drilling depth no more than 600m;Each bit should be matched with corresponding shroud.

Operating mechanism

Compressed air flows into the annular space of the double-wall drill pipe, then into the inner pipe from the drilling tools in the bottom of hole, and carries cuttings out to the ground through the inner pipe.

Applications

RC tools are used in geological exploration, water well drilling etc
