Carboloy insert identification

[OrangeAlpine]

I have several old Carboloy inserts. I would like to identify them in order to determine if they would be appropriate for the kind of machining I do. Anybody know where this information may be found? An example: The card some of the TNMG inserts are mounted on says "433E" and "370". The TNMG is decipherable, the rest means nothing to me.

These numbers are relates to size and radius of the cutting tip, also the carbide grade, 320 softer but less brittle, 370 harder, lasts more on hard steels but is more brittle. So if you are turning over slots it will chip or break.The 433 is the ASA, Almost all catalogs will have the full explanation, search the net for carboloys nomeclature.

Thanks for the explanation. I have not been able to find any catalog nomenclature explanation that I can decipher. It seems there is a certain level of understanding and intelligence required and I'm not there.

Be patient, is not rocket science, let my do more research. If carboloy uses the ANSI STANDARD, the 370 is as said, the carbide and cermet class, the higher the number, the harder but brittler. The last number on the 433, means a radius of 3 mm,
the 4 means size. The E i dont know and the mid 3 neither.
I just found all about it on page 741 and 742 of Machinerys Handbook. The 4 means the number of eigths of an inch of the inscribed circle of the poligon. The E means the relief angle is 20deg.
