What this does and does not mean
It means the maker positions ACP2000 as the newer grade for the work ACP100 was used for. It does not say ACP100 is discontinued, and it does not say every insert shape and chipbreaker you buy in ACP100 exists in ACP2000.
Before you switch:
- Check that your exact insert designation and chipbreaker are offered in ACP2000 in the maker's current catalogue.
- Start from the maker's recommended cutting speed for ACP2000, not the numbers you ran with ACP100.
- Run both grades until the edge is worn out on the same part and compare parts per edge. One part is not a result.
