RC Drilling Rods

Boart Longyear 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
Remet
Metzke

Metzke-type thread is one of the recognized standard threads used in reverse circulation drilling. Boart Longyear 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. Boart Longyear 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.
