The dimensions shown on the following illustrations are considered standard. Hook Tongue or
Safety Tang is safer to use if the punch is to be used in sections where weight or dimensions of
punch
are great, or where stripping pressure would create an extreme downward pull as in the
case of a
channel forming die.
SP-500 Punch and SD-125 Die
We do not recommend these for high production or where punch is cut into sections,
but it is an economical die set for light sheet metal.
