What this does and does not mean
The maker marks the old MT9015 items it lists as discontinued, phased out or obsolete and names items in MP9015 as their replacement. That record is per insert: your exact MT9015 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 MP9015 in the maker's current catalogue.
- Start from the maker's recommended cutting speed for MP9015, not the numbers you ran with MT9015.
- Run both grades until the edge is worn out on the same part and compare parts per edge. One part is not a result.
