Hydraulic External Cutter Type WD-S
The Hydraulic External Cutter Type WD-S is an external pipe-cutting tool, which knives are hydraulically actuated by circulating drilling hydraulic load. It is usually connected with the washover pipe and can cut the fish at its any section. Compared with the mechanically-actuated one, it has the advantages of simple operation and quick cutting.
