INLOK™ RC Drill Rods

INLOK™ RC Drill Rods

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.

The INLOK™ product range includes specifically engineered RC drill rods, inner tubes and safe handling equipment. The safe handling equipment is used to install and extract inner tubes from reverse circulation drill pipe and can be used on the slips table during normal drilling operations to avoid the unnecessary handling of heavy RC drill rods that can weigh up to 170kgs each.

The improvements in safe handling are only half the story. With the Harlsan RC Drilling INLOK™ system, inner tubes are “locked” stopping them from moving or spinning inside the rod. The elimination of this movement inhibits both O-ring and urethane seal grooving of the inner tube ends, reduces wear to the inside rod shoulder and circlip breakages are virtually eliminated.

The INLOK™ safe handling equipment only requires 100psi (689.5 kPa) of rig air to operate and comes contained in a hard case with all attachments for safe operation. The Harlsan RC Drilling INLOK™ System will reduce maintenance & increase the life of your reverse circulation drill string. Call today and find out more.
