These form indexable inserts have
two cutting edges in the new condition.
They can be employed on both
the right-hand and left-hand sides.
The indexable inserts can be reground.
Regrinding entails surface
grinding of the cutting faces, but on
one side only.
When regrinding sets, note the difference
between right-hand and lefthand
indexable inserts.
