1. A tough, multi-purpose auger head for full range drilling.
2. Uses replaceable cone-shaped carbide insert bits depending upon the formation requirements.
3. Bits are designed to revolve during the cutting action for a more uniform wear pattern and longer service life.
4. Recommended for abrasive conditions and difficult hard formations.
