Abstract
A side outlet, self-stripping punch adapted to be mounted in a bore in a die board. The self-stripping punch includes an elongated, cylindrical base having a cutting edge on the top end and a pair of locking ears on the bottom end to prevent rotation of the punch in the die board. The locking ears are formed by upsetting them from the punch base, and they each have a flat face disposed on a common plane passing through the longitudinal axis of the punch.
