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. This is largely due to our innovative designs, and we're continuing to develop the capabilities of this valuable sampling method. Partner with Sandvik for your reverse circulation down hole hammer drilling.

Advantages

• 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
