RC drilling tools offer a cost effective heavy duty sampling system for obtaining continuous, high quality geological samples.
 M a ximizing energy output and minimizing air consumption, environmentally,good cutting flushing,thereby combining excellent drilling performance,usually applied in mineral exploration drilling.
1 . The samples can be flushed via inner pipe smoothly under small resistance.
2. The rock cutting will not be flushed into the air, it is a environmentally drilling solution. 
3. Low air consumption.
4. Accurate sampling
5. Inner pipe, shrouds and sample tube are produced by special alloy steel,all of their flushing surface are strengthened
