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.

Face shape Features
Concave Face
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
Flat Face
1. Have a superior performance in hard, abrasive and broken rock conditions
2. They however have a slower penetration rate in comparison to a concave face bit
Convex Face
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
The appearance of the picture is different from that of the actual product, and the actual product is the standard.
