Iscar IC5500: the maker lists IC8355 as its successor
ISCAR puts Iscar IC8355 against IC5500 in its own catalogue material. We publish the pair only because the maker published it; the source is below.

ISCAR calls the old grades phased out in this announcement, which covers its BTA deep-hole drilling inserts.
What this does and does not mean
The maker marks the old IC5500 items it lists as discontinued, phased out or obsolete and names items in IC8355 as their replacement. That record is per insert: your exact IC5500 insert may point to a different grade or have no successor.
Before you switch:
- Check that your exact insert designation and chipbreaker are offered in IC8355 in the maker's current catalogue.
- Start from the maker's recommended cutting speed for IC8355, not the numbers you ran with IC5500.
- Run both grades until the edge is worn out on the same part and compare parts per edge. One part is not a result.
