Product Advantages

R.C. Drilling, referred to as "Centre Sample Recovery" or "Dual Wall Drilling", employs a Dual Wall Pipe where the drilling medium (normally high pressure air) is passed between the outer and inner tubes down to the face of drilling bit where it is returned up the centre tube along with the sample cut by the drill bit.

No contamination: The R.C. System collects sample through the recovery holes in the face of the drill bit immediately as the cuttings are formed. The drilled sample does not have to travel the length of the hammer where contamination and loss of sample occurs.
Higher Production: In broken and fractured ground conditions, the R.C. will often outperform conventional hammers in terms of penetration rates.
Dry Sample: Even in certain water-bearing strata, it's possible to collect a dry sample because cuttings are collected as they are formed through the face of the drill bit.
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. With bit matched to chuck size, recovery rates up to 98% are achievable.
