To install the punch, insert it into the punch holder with
its cutting edge facing forward so that the pin in the

OPERATION
CAUTION:
Hold the tool firmly with one hand on the main
•
handle when performing the tool.
Pre-lubrication
Coat the cutting line with machine oil to increase the
punch and die service life. This is particularly important
when cutting aluminum.
Cutting method
013359
Smooth cutting is achieved by holding the tool upright
and applying gentle pressure in the cutting direction.
Apply tool oil to the punch about every 10 meters (32.8
feet) of mild steel or stainless steel to be cut. Light oil or
kerosene should be used to keep an aluminum
lubricated continuously. Failure to lubricate aluminum in
the cut will cause chips to adhere to the tool, dulling the
die and punch and increasing load on the motor.
Cutouts
013360
Cutouts can be done by first opening a round hole of
about 42 mm (1-5/8") diameter or more in the material.
