Why would I not expect the same results?
Because it is the one thing that you changed.
If everything else has not changed and you changed one thing - that would be the most suspect.
In systematic troubleshooting - you want to eliminate the easiest things first.
So - by cutting the same program in the same wood - but with a "known" good cutter - you will possibly eliminate the bearing and also the insert cutter as suspects, OR - prove beyond any shadow of doubt that there is still a problem - depending on the results. Doing the test will provide information that you do not have now.
Going after the bearing is not the easy stuff - and that may not be the problem.
No one has yet addressed the possibility of bearing failure. Still wondering if that is the cause????????
