The design of our drilling bits is simple and reasonable, with the characteristics of high flat degrees, smooth holes, high rigidity, fast punch speed, low failure rate, stable drilling, high penetration rate. The drilling depth exceeded customer expectations and was well received by customers.

THE USE AND THE ADVANTAGES OF THE R.C.DTH HAMMER And Bit

1. No contamination
The R.C. System collects sample through the recovery holes in the face of the drill bit immediately as the cuttings or sample is formed. The drilled sample does not have to travel the length of the hammer where contamination and loss of sample takes place.
2.Higher Production
In broken and fractured ground conditions,the R.C. will often out perform the conventional hammer in terms of penetration rates.

3. Dry Sample
Even in certain water bearing stratas it is still possible to collect a dry sample because the cuttings(sample)are
collected as they are formed through the face of the drill bit.

4. Higher Sample Recovery
Because the sample is collected through the face of the drill bit there is no loss of sample when drilling through broken or fractured ground.And since the bit matched to the chuck size ,there is very little bypass of sample and recovery rates of up to 98% are generally achievable.
