Testimonial

“Reverse circulation drilling has proved to be an effective means of providing large representative and high quality samples in open pit gold mines for over three decades. Applying this drilling methodology to underground grade control at Sunrise Dam has demonstrated that it can be as effective as surface RC for defining ore.”

The INLOK Drill Rod Range

QUICKER. SAFER. MORE EFFICIENT.

Any driller who has used a sledgehammer to manually remove a collapsed Inner Tube from an RC drill rod or pipe will know how unsafe it can be. The whole procedure is inefficient and involves injury risk from the associated manual handling.

The Harlsan RC Drilling INLOK™ product range provides a safe and controlled solution to these problems.
