This helical cutterhead is equipped with indexable
carbide inserts. Each insert can be rotated to reveal
any one of its four cutting edges. Therefore, if one
cutting edge becomes dull or damaged, simply rotate
it 90˚ to reveal a fresh cutting edge (see Figure 41).

To rotate or replace helical cutterhead insert:
1. DISCONNECT MACHINE FROM POWER!
3. Open pulley cover to expose cutterhead pulley.
4. Rotate cutterhead pulley to provide access to
insert(s) to be rotated/replaced.
5. Put on heavy leather gloves for protection.
6. Remove any sawdust or debris from head of
insert, Torx screw, and surrounding area.
7. Remove Torx screw and insert, then clean all
dust and debris from both parts and pocket they
were removed from.
Tip:
Use low-pressure compressed air or vacuum
nozzle to clean cutterhead pocket.
8. Re-install insert so that a fresh cutting edge
faces outward, making sure it is properly seated
in cutterhead pocket.
— If all four insert cutting edges have been
used, replace insert with a new one. Always
position reference dot in same position when
installing a new insert.
9. Lubricate Torx screw threads with a small
amount of light machine oil, wipe excess off,
and torque screw to 48–50 inch/pounds.
Note:
If too much oil is applied to the threads,
excess will attempt to squeeze out of threaded hole
as you install insert and force it to raise slightly,
making it out of alignment.
2. Remove cutterhead guard from table, and lower
infeed and outfeed tables as far as they go to
provide access to cutterhead (see Figure 42).

Each insert has a reference dot on one corner. As the
insert is rotated, the reference dot location can be
used as an indicator of which edges are used and
which are new. When the reference dot revolves back
around to its starting position, the insert should be
replaced.
