Each of the dies at the angle iron shearing station
have four different mounting positions to use a
different set of cutting edges.
Because of the critical positioning in relation to
each other, these dies cannot be sharpened.
When they become damaged or dull, call Grizzly
Tech Support at (570) 546-9663 to order new
ones.
To re-install the angle iron shearing dies, use the
same tools, clearance specification, and proce

dures used in re-installing the flat stock shearing
dies (refer to Page 45).
