Hand Threading -water jet maintenance

1.Secure the coned tubing in a tube vise. No more than the recommended length of tubing should 

extend beyond the face of the vice. See Table 2-10, Recommended Extension Length.

2.Apply cutting oil to the end of the tube and slide the threading tool on the tubing.

3.Grip the handles of the tool firmly, apply steady pressure and turn the tool counter- clockwise. 

Approximately every half turn, reverse direction to break off and remove the chips.

Apply cutting oil frequently and liberally throughout the cutting operation. A medium weight 

cutting oil with high sulfur content is recommended.

4.Continue threading until the proper thread length is reached, see Table 2-9, Column L. Remove 

the tool from the end of the tubing.
