Matrix Reverse Circulation Dual Tube Drill Rod for Underground Drilling
Roschen drill rods feature a combination of exclusive heat treatments and innovative engineering to provide the ultimate in performance and longevity. Roschen RC drill rods expand your drilling capabilities and lower your total drill rod cost per meter/foot in deep, deviated, and demanding wireline coring applications.
REVERSE CIRCULATION DRILL PIPE
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.
Roschen Drilling Products is the recognized industry leader in RC Drilling Tools. Roschen RC tools are distinguished by their superior performance, reliability, and durability. 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.
We address the underground RC drilling operations with our M3.25 RC Drill Rod. Surface mineral exploration applications utilize our M4 – 4.5” – 5.5” – 6” RC Drill Rod while additional larger diameter RC Drill Rods 7″ – 9 5/8″ – 10.75″ are used for bulk sampling, mine dewatering, and water resource applications.
