To install the punch, insert it into the punch holder with
its cutting edge facing forward so that the pin in the
punch holder fits into the groove in the punch. Install the
screw and lock nut. Then tighten them securely.
NOTE:
• When installing the screw and lock nut, be sure
to tighten securely. If they become loose during
operation, the tool may break down.

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
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 lubri-
cated 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
Cutouts can be done by first opening a round hole of
about 42 mm (1-5/8") diameter or more in the material.
