I have a ccmt insert in front of me thats bigger than a 06 but smaller than a 09......... it measures 8mm across the cutting edge. I can't seem to find anywhere that mentions a 08 size. has anyone seen them before?
Any idea what it is from? Could it be something other than a CCMT? For example I have some Stellram boring bars that take EPMT inserts which at first glance look similar to a CCMT.
good call hood, I will get out to the workshop in the morning and have a proper measure of the angles and see if theres difference. il take a few pictures too .
its an insert for one of the tools out of my line borer, they are like small boring bars. I have small ones which take ccmt06's big ones which take ccmt09's and the middle sized one is the odd one out!!
curiosity got the better of me so I just ran outside to check, it looks like the angle is slightly less on the middle sized insert, so I looked at the EPMT inserts as you suggested and the are 75 degrees instead of the ccmt 80 degrees. !!
I think you may have solved the problem, il check properly tommorow
they are not a matched set as such, just three different sized sets of bars. if that makes sense.
