Model LM-TX Rotating Spear

For LM-TX rotating spear, a bearing system is installed between the mandrel and spear rod. During the cutting operation, the mandrel joint drives the tubular column at the lower end of the mandrel to rotate together through the connecting screw threads, which greatly reduces the friction resistance in the process of rotation and improves the cutting efficiency.
