This Auger has a set screw that clamps it to the bottom of a pipe that would be screwed into the mud or sand.
This works great in river banks where the current would slide the pipes out of the mud.
The auger grips into the ground and screws in for install and unscrews for removal.
The turning of the pipe can be done with the pipe puller found here in the dock tools category.

To avoid confusion when buying pipe that fits in this, the industry standard calls the pipe size as 1.5″ schedule 40 but the O.D. is actually 1 7/8″.
