**COMACCHIO CX 20A DD** is an exploration rig for diamond core drilling. The method recovers continuous rock cores for geological investigation. Controlled rotation and feed support the coring process; the barrel, rods and drilling fluid are selected for the formation and required sample diameter.

The CX 20A DD has a particularly long feed stroke within the CX 20 class. This arrangement supports long rod elements with the corresponding coring equipment.
