REVERSE CIRCULATION

The mineral exploration industry utilizes reverse circulation drilling to economically collect representative samples when searching for ore bodies to develop. The reverse circulation method is used predominantly in tough, broken, and abrasive formations. This method offers several economic advantages over diamond coring in these environments as well.

We manufacture a complete line of reverse circulation drilling tools and support the range with a comprehensive array of associated purpose specific accessories including – Interchanges- Rock Bit Adaptors – Subs – Back Reamers – Hoisting/ Lowering – Drill Collars – Swivels – Fishing Tools and much more.
