Auger drive attachments for excavators, backhoes and skid-steeer loaders

The EBA range of auger drive units allows you to quickly convert your excavator, backhoe or skid-steer loader into a drill rig by simply changing the attachment.

These auger drive units are ideal for drilling shallow holes in soft to compact soils, cobbles and in soft rock with compressive strengths up to 50 MPa. For use in harder rock, KEMROC have developed special drilling tools to ensure higher drilling speeds.

EBA-D range:
Direct drive, short and heavy duty construction, hexagonal drive shaft

EBA-P range:
Planetary gear drive, high torque in a compact size, square drive shaft

  • High torque hydraulic motor
  • Robust and rigid bracket
  • Heavy duty bearings
  • Wear resistant augers
  • Auger drives for tough applications
  • Allignment monitor to garuantee vertical drilling

Notes for drilling with KEMROC auger drive units:  When mounted on an excavator arm, the augers are not supported in a feeder. Due to the natural curve of the excavator arm, augers can be bent during drilling. Therefore, special care must be taken to ensure that the augers are always working ver­ctially. Only by keeping the auger in the vertical position can you guarantee a straight bore hole. Take great care to avoid bending the augers. Exces­sive bending of the auger can result in the hex drive breaking and damage to the auger drive. Select the auger rotation speed that corresponds to the auger diameter and material being drilled. Generally, rotation speeds should be lower for larger diameter augers or when drilling in harder material.
