Theodore A, Matt G: This is a punch designed for use with spirol pins. Look closely and you will see that little ole round protrusion at the end of the punch. That little difference causes the spirol to contract its diameter and thus easily removed. Of course, some PB Blaster helps also...These punches are readily available. I've seen 'em at Case/IH dealers, for example.
