Product Description

Product Description

WD-J type mechanical external cutter is an automatic spring-fed cutter that provides fast, efficient, smooth external cutting and recovery of long sections of tubing, drill pipe and casing. The spring-fed feature prevents excessive strain on the knives which could have caused the knives to burn or break when the cutter is being applied on the rig floor.

Work Principle
Connect the tool with the washover pipe and lower it to the predetermined cutting position. Lift the cutter, the circlip above the clamping sleeve inside the cutter holds the shoulder of the drill pipe (fish) sub. As we continue to lift the cutter, through the shear  pin, the body pushes the feed ring upwards, compressing the spring. When the lifting force exceeds the shear pin cut-off load, the shear pin cuts off, releasing the compressed spring. The spring repels, moving the feed ring in a downward direction, guiding the knives to rotate towards the cutter center. At this instance, rotate the tool, the release of spring's elastic potential energy gradually pushes the feed ring and knives downward until the drill pipe (fish) is cut. After cutting, the clamping sleeve clamps on to the cut tool joint, allowing it to be extracted with the cutter.

When ordering please specify:

• Hole size;
• Pipe O.D to be cut;
• Top connection.
