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.
