Detailed introduction

The Mechanical Internal Cutter Type NG is used to cut casing, oil tubing and drill pipe. It features a device that permits the operator to set the cutter to any depth, and reset it to another depth without coming out of the hole. After mechanically anchored, it is pressured to rotate for cutting the drill string. If it is equipped with the spear, cutting and recovering can be completed at the same time.
