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.
