Casing Cutters Functions:
When a string of casing is stuck in a drill hole , a portion of it can be salvaged by cutting the casing above the stuck zone with a casing cutter. The casing can be cut at any desired point in the string.
The cutter connects directly to the drill rods and the pressure of the circulating water against a piston forces the steel or tungsten carbide tipped cutters out against the casing. After the casing is cut the pressure is released and the cutters retract.
