We offer a full range of reverse circulation down the hole hammers and bits, to suit all depths and ground conditions.
Due to its high-quality sample results, and speed of operation for shallower holes, reverse circulation drilling is becoming increasingly popular around the globe. In fact, it’s the most widely accepted chip sampling method.
High penetration rates in all rock conditions.
Quality samples from areas of lost circulation.
Large, uncontaminated sample return.
Increased longevity means lower cost per meter.
The option of diamond-enhanced carbide bits for deep and abrasive drilling conditions, with no bits sharpening required.
