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