Rotating/Replacing
Cutterhead Inserts
figure 31. insert rotating sequence.
the spiral cutterhead is equipped with indexable
carbide inserts that can be rotated to reveal any
one of their four cutting edges. if one edge of the
insert becomes dull or damaged, simply rotate it
90° to reveal a fresh cutting edge, as shown in
figure 31.
5. remove the torx screw and the insert, then
clean all dust and debris from both parts and
the pocket they were removed from.
Note: Proper cleaning of the insert, Torx
screw, and the cutterhead pocket is critical to
achieving a smooth finish. Dirt or dust trapped
between the insert and cutterhead will slightly
raise the insert, and make noticeable marks
on your workpiece the next time you cut.
Tip: Use low-pressure compressed air or a
vacuum nozzle to clean out the cutterhead
pocket.
6. replace the insert so that a fresh cutting
edge faces outward.
— if all four insert cutting edges have been
used, replace the insert with a new one.
Always position the reference dot in the
same position when installing a new insert
to aid in the rotational sequencing.
7. Lubricate the torx screw threads with a very
small amount of light machine oil, wipe the
excess off, and torque the screw to 50–55
inch/pounds.
Note: If too much oil is applied to the threads,
the excess will attempt to squeeze out of the
threaded hole as you install the insert and
force it to raise slightly, which will make it out
of height alignment.
