Walter WSP45S: the maker lists WSP45G as its successor

What this does and does not mean
The maker marks the old WSP45S items it lists as discontinued, phased out or obsolete and names items in WSP45G as their replacement. That record is per insert: your exact WSP45S 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 WSP45G in the maker's current catalogue.
- Start from the maker's recommended cutting speed for WSP45G, not the numbers you ran with WSP45S.
- Run both grades until the edge is worn out on the same part and compare parts per edge. One part is not a result.
