the required depth is reached , rotation is reversed carefully,
whereupon the reamer swings in , allowing the drill bit assembly to
be pulled up through the casing.

Casing tubes that are to be left in the drill hole should be sealed
at the bottom of the hole by means of cement grout or some other
sealing agent.
