This self contained ‘C’ Frame Unit utilizes pilot pins in the bottom of the holder for mounting on 1/2" thick Templates with nothing attached to the Press Ram. The tubing is supported on all sides during punching. The Units provide straightthrough holes with one punch. The top hole has distortion, which varies depending upon Punch size, tube OD, wall thickness and material type. The bottom hole is punched into a die, providing minimal distortion.
