NOTE: When punching larger diameter holes or alloy steels, set the down stroke of the machine
so that the punch stops just above the plane of the die, approximately fifteen thousandths
of an inch (.3mm). This will reduce the punching shock encountered in these applications.
Rated on mild steel having 65,000 psi tensile.
MAXIMUM MATERIAL THICKNESS IS 1 INCH (25MM).
