The helical cutterhead is equipped with 4-sided
indexable carbide inserts. Each insert can be
removed, rotated, and re-installed to use any one
of its four cutting edges. Therefore, if one cutting
edge becomes dull or damaged, simply rotate it
90˚ (as shown below) to use a sharp cutting edge.
The inserts have a reference dot on one corner.
The position of the reference dot on installed
inserts can be used to track which edges are
sharp/unused and which edges are dull or dam-
aged. Replace inserts once the reference dot has
been rotated back to its original position.
