PUNCH AND DIE LUbRICATION
Proper lubrication is essential to prolong punch
and die life, and is achieved by occasionally
fully submersing the punch and die in a small
container of the proper lubricant.
To further ensure a smooth cut and long punch
life, always lubricate the cutting path with
cutting oil. When cutting steel or stainless
steel, lubricate path of cut before starting work.
When cutting aluminum, lubricate path of cut
while making the cut. Since the punch cuts on
The corrugated nibbler is especially designed
for working with corrugated sheets of both
trapezoidal and rectangular profiles.
Always use both hands to guide the nibbler.
Do not use force; this will lead to premature die
and punch wear.
Before running the nibbler, be sure the punch
and die are properly lubricated. See "Punch
and Die Lubrication" section.
Never start the nibbler with the punch and die
in contact with the material being cut.
Always be sure material is resting on lower die
during operation.
Nibbling to a Scribed Line
or with a Template
Cuts may be executed easily by guiding the
nibbler along a template or a straight edge.

the downstroke, the upper side of the cut
should be lubricated.
When cutting steel, use a cutting oil or an SAE
30 weight oil.
When cutting aluminum, a mixture of 7 parts
kerosene and 3 parts turpentine should be
used.
Should punch jam, immediately switch off
nibbler, re-lubricate punch and die, and
remove tension from sheet.
Tool Tips
For internal cuts, a starting hole of .827"
(21mm) is required, so the die can be inserted.
When cutting, guide the unit with a slight thrust
in the cutting direction. Cutting takes place
during the downward movement of the punch.
The chips are ejected downward through the
knurled nut.
By rotating the die holder, cutting can be
preformed at a right angle to the forward axis
of the machine.
Loosen the winged screw and turn the die
holder (including the die and knurled nut ), to
the right or left by 90°. Re-tighten the winged
screw. The winged screw must engage one of
the holes in the die holder.
