OPERATION

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
► Fig.8
Hold the tool so that the cutting head is at a right angle
(90°) to the workpiece being cut. Move the tool gently in
the cutting direction.
Cutouts
► Fig.9
Cutouts can be done by first opening a round hole over 21
mm in diameter which the cutting head can be inserted into.

metals.
Always hold the tool body parallel to the grooves with
the cutting head at a right angle (90°) to the cutting
surface as shown in the figure.
