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.

Face shape Features
1. Capable of drilling straighter holes in medium to hard rock
which is broken or less consolidated
2. Offers high penetration rate in the above stated rock conditions
3. Has excellent air flushing characteristics
4. Predominant face style for majority of drilling conditions
1. Have a superior performance in hard, abrasive and broken rock
2. They however have a slower penetration rate in comparison to a
concave face bit
1. This face has been designed to offer high penetration rate in
soft rock such as shale, limestone etc
2. They are recognized for having excellent capability for drilling
into moderately consolidated rock conditions
