Deep exploration drilling 140mm PR54R /PR54 RC drill bit, with hard formation
Description
Mainly used for deep exploration drilling, and stope ore controlling.
Main product features:
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.
In broken and fractured ground conditions, the R.C. will often out perform the conventional hammer in terms of penetration rates.
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.
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.
