CONTINUOUS FLIGHT AUGERS AND BITS Finger bit type multi-purpose A tough, multi-purpose auger head for full range drilling. Uses replaceable borium or carbide insert bits depending upon the formation encountered. Borium tip bits are suitable for work in light to moderate soil formations such as silt, sand, fine gravel and shale. Tungsten carbide bits are used for more abrasive conditions or for longer bit life in any of the above formations, but are not recommended for nonuniform formations such as gravel where impact or shock might be encountered. Bits are held in place by malleable iron bit wedges that deform as necessary to grip bits within the head. Cutterhead sizes are identified by the hole size, not actual flight diameter.

CONTINUOUS FLIGHT AUGERS AND BITS Bulldog head A tough, multi-purpose auger head for full range of drilling. Uses replaceable cone-shaped carbide insert bits depending upon the formation requirements. Bits are designed to revolve during the cutting action for a more uniform wear pattern and longer service life. Recommended for abrasive conditions and difficult hard formations. Note: Bits are furnished with lock rings installed. Drill head O.D. is approximately 10% larger than corresponding auger flight O.D. Sizes are identified by the hole size, not actual flight diameter.
