Extrusion Punch

The bullet punch is used to manufacture extruded edges from a pre-existing hole. These extruded holes are typically used to accept sheet metal screws, provide spacing in panels, strengthening holes in parts that are mounted with rods or bolts, or to allow tapping into a deeper distance past the material thickness. On what applications do you use extruded holes?

Urethane Strippers

Stripping material is a crucial part of the punching process. The video on the left shows the standard stripper assembly on the Piranha P-50 ironworker. The yellow base is the stripper foot and the black tubes on either side of the punch are the urethane strippers. When released the urethanes press down on the stripper foot. The stripper foot then strips the material off the punch.

The photos on the right show the different urethane strippers we stock. Unlike the black Piranha strippers, the red and blue strippers slide over the punch to strip the material. The colors signify different hardness/durometer of urethane. The harder urethane (red) is used for thicker material, while the softer urethane (blue) is used for thinner material. It’s important to use the correct urethane to ensure the material will not distort while stripping. When the urethane starts to crack, it is time to be replaced. This helps ensure quality holes and extended tool life.
