View Full Version : Carbide insert number question

11-12-2011, 10:27 PM
I see on e-bay some inserts that I use but the third number is smaller. Is that the insert thickness?
VNMG331MS and I have VNMG332?? Do you think it will work with my holder?

The third number in your example is just the radius on the cutting tip. The smaller the number the smaller the radius. Yes, they will work. http://www.arwarnerco.com/warner_products_inserts_chart.html

The third digit should be the nose radius, in 64ths, I think.

I just ran across this page that will detail an insert as you type it in.
Since I always get confused with the charts I like this one better:

Nice for metric ISO-labeled inserts, not-so-much for ANSI. Maybe I'm doing something wrong, but it doesn't seem to take CNMG 432, the most common insert in the world.

For the record, I do know that a CNMG 432 is, in ISO language, a CNMG 120408.

This one will give both, though you have to read it rather than input data.
