ISO Code System for Turning Inserts Explained: A Complete Guide
Learn how to decode the ISO code system for turning inserts. Understand shapes, relief angles, and tolerances to choose the perfect CNC tool.www.cutwel.co.uk
For ceramics, CBN etc, there is no real standard. The further into the ISO code you go, reading from left to right, the more manufacturer-dependent it becomes (e.g. for standard carbide insert, a Sandvik Axyz carbide grade number will not be the same as Iscar Axyz grade, even assuming Iscar use that number at all).

Don't suppose you have the email handy.I normally email MSc technical help, get the insert code then search eBay![]()
Interesting no tips come up in eBay using CNMG 1204.Just to add, CNMG 1204**
Those two options are suggested but I though a broader search would be more productive.Plenty come up for me so not sure why you didn't get any.
You could try CNMG 120404 or CNMG 120408 ETC.
