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 scribed lines - For straight
cutting, secure the die from rotating, by
tightening the retaining screw. Straight cuts
are easily made by guiding the nibbler along a
ruler 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.
Curve cutting - For curve cutting, loosen the
retaining screw. The die is then free to rotate
and position itself in the direction of cut.
Internal cuts - For internal cuts, a starting hole
of 9/16" (16mm) is required, so the die can be
inserted.
Nibbling to template - The bottom of the die
traces the template. Note that due to a
distance of 3/16" (4.5mm) between the
template and cutting edge of the die on either
side, the cut-out and template size do not
correspond exactly. The retaining screw must
be loosened.
Freehand cutting - For easy movement of die
about the punch, additional accessories are
required. Accessory die holder and dies for
corrugated or flat stock may be purchased
from your Bosch distributor. See the Bosch
Catalog for accessory part numbers.
