COMACCHIO X CX 20 RC Reverse Circulation Drill Rig
COMACCHIO CX 20 RC is an exploration rig for air reverse-circulation drilling. Cuttings return through the inner tube of a dual-wall drill string to the sampling equipment at the surface. The air supply, hammer and sampling system are selected for the diameter, depth and formation.
The CX 20 RC increases pullback capacity for heavier RC drill strings. Available mast versions can be matched to rod length and the operating sequence.
