Guide to Selection of TerraMacs Horizontal Directional Drilling Machines
Note - The following table is offered as a comparative guide only and a means to readily identify the most likely drill rig to suit your needs. TerraMacs accepts no liability whatsoever where machines fail to perform to stated levels, as ground conditions, drill operator techniques, fluids, tooling and machine speeds are all highly variable and contribute to the effectivity and productivity of the drilling operation. It may be possible to drill larger diameters over shorter lengths or smaller diameters over longer lengths. We strongly recommend that you discuss your requirements with your distributor or contact TerraMacs before making a final machine selection.

Many of our drills have specification and feature options which are not shown in this table to aid clarity. Mini Mac (Pit Drill & Surface Launch) TX150B Midi Mac Mighty Mac
