Our pier drilling bits range in size from 12 inch to 36 inch. The drill setup is mini excavator-mounted, has two speeds for varying soil conditions, and is capable of depths to 14 feet without stemming. This equipment is ideal for a wide variety of pier drilling operations.

Some circumstances may call for a larger bore or more depth. We have access to larger rigs when needed.
