Geopower – Excavator Mounted Geotech Drill

MPP’s excavator mounted Geopower drill, was developed for geotechnical and multi-purpose drilling requirements. The rig can easily be adapted to mount on most mid sized excavators. Featuring our PII top drive with high speed coring option, the Geopower excavator mounted drill can be used for auger, air rotary/odex and diamond core drilling. An SPT auto hammer, hydraulic head slide winch and auto hammer mounting arm are all standard features ideal for typical geotechnical work. The Geopower excavator mounted drill mast is a simple, efficient unit and an inexpensive alternative to a complete drill.


  • Can be mounted on most mid-sized excavators
  • Multi-purpose geotechnical machine – Auger, diamond core & air rotary
  • Auto hammer, winch, hydraulic head slide all standard components
  • Inexpensive alternative to full drill rig
