REVERSE CIRCULATION PERFORMANCE TOOLING
 

Reverse-Circulation (RC) drilling is used to collect rock samples quickly and efficiently using a large rotary drill and air compressor. The high speed and lower cost per meter of RC drilling makes it ideal for obtaining mineral samples in the early phases of an exploration project.

Reverse Circulation Drilling Rods

 

Roschen offers drill rods in both Metzke and Remet-type threads for complete compatibility with other systems. Our robust drill pipe provides 360°of contact from inner tube collar to outer tube, and is designed to be easily replaced in the field, minimizing costly downtime.

 

Metzke 
 

Metzke-type thread is one of the recognized standard threads used in reverse circulation drilling. Roschen Metzke-type drill pipe features high-grade alloy tool joints and inner tube assemblies, and easily replaceable inner tubes with special joints that offer superior stabilization with minimal flow restriction. Metzke-type thread uses a strong 4 threads per inch design and more robust 90°tool joint mating surface.


Remet 
 

Remet-type thread is another recognized standard in RC drilling. Roschen Remet-type drill pipe features high-grade alloy tool joints and inner tube assemblies. Its easily replaceable inner tubes with special joints offer superior stabilization with minimal flow restriction. Remet-type RC pipe features sealing o-rings on the pin portion of the inner tube assembly, providing optimal inner tube sealing and airflow.
