Medium Size Rig

Comacchio MC450P & MC450P.1

The MC450P is the big brother of the MC405. Whilst still very compact, not much bigger than the MC405, this machine is considerably more powerful, allowing boreholes to be drilled deeper and faster.

The MC450P.1 is the same basic machine, fitted with a mechanised drill rod handling arm.
