Hydraulic Powered Portable Roofbolters: Z DRILL
The hydraulic powered Z Drill may be configured to run off of any number of power sources and various pressures. All Z Drills may be configured to: run off high pressure (5000 psi) or low pressure (2175 psi) systems; reverse rotation; wet, dry and dust collection (vacuum) drilling.
MPI has the Long Z Drill, Short Z Drill and Mini Z Drill (low profile).
