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.
