Higher Production 5" RC Hammer RE542 For Deep Exploration Drilling

Hole Range 113mm-130mm Higher Production 5“ RC Hammer RE542

Introduction of R.C. Drilling

RC series reverse circulation DTH Hammer is the latest developed product of our company. It is mainly used for deep exploration drilling and ore grade control.

The use and the advantages of the R.C. DTH Hammer

I) 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 strata, 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

4) Higher Sample Recovery
Because the sample is collected through the face of e 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.
