These units provide two sided punching in round or square tubes.

Each assembly top and bottom contains a Punch to pierce two holes in-Iine on each side of the tube. The tubing is supported on all sides during punching.

If only one hole is desired, the removal of the bottom Punch accommodates this option. The Units require upper and lower Templates. One template is attached to the Ram of the Press, the other to the bed.

A tube is placed into the lower assembly, the Ram is then lowered for line up adjustment, and the units are then secured to the Templates and are ready to punch holes. Due to lack of Die, unsupported tubes distort when punched.
