TITLE OF THE INVENTION EXTRUSION PUNCH AND METHOD OF CONSTRUCTION ABSTRACT OF THE DISCLOSURE An extrusion punch, especially for use in a back extrusion process, wherein a hard wear resistant material is joined on one end to a steel punch body. The hard wear resistant material is joined at the tip of a steel body so as to prevent wear due to abrasion on the punch caused by the material being extruded in a die means. The hard wear resistant end cap on the tip of the steel body is joined so that it may easily and quickly be replaced when the punch is in position on the machine thereby providing less down time for maintenance on the extrusion press. The method of joining the hard wear resistant end cap to the steel body minimizes the conditions which tend to fracture hard wear resistant material.
