What this does and does not mean
The maker marks the old WPP20 items it lists as discontinued, phased out or obsolete and names items in WPP20G as their replacement. That record is per insert: your exact WPP20 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 WPP20G in the maker's current catalogue.
- Start from the maker's recommended cutting speed for WPP20G, not the numbers you ran with WPP20.
- Run both grades until the edge is worn out on the same part and compare parts per edge. One part is not a result.
