What this does and does not mean
It means the maker positions GC4415 as the newer grade for the work GC4315 was used for. It does not say GC4315 is discontinued, and it does not say every insert shape and chipbreaker you buy in GC4315 exists in GC4415.
Before you switch:
- Check that your exact insert designation and chipbreaker are offered in GC4415 in the maker's current catalogue.
- Start from the maker's recommended cutting speed for GC4415, not the numbers you ran with GC4315.
- Run both grades until the edge is worn out on the same part and compare parts per edge. One part is not a result.
