Hey Kyle,

this is not the right bit for this. I would mill such pockets with a 8 mm bit, not a 29 mm bit. And at 24,000 rpm.

Also the milling motor you use is not made for this, neither for such large diameter bits, nor for stationary use in a cnc machine. It’s a [hand router](https://forum.onefinitycnc.com/t/does-radial-runout-change-as-the-router-heats-up/13258/9)!

I fully agree with what the others said.
