Largest Bottom Cleaning Bit that can be used on XXL Shapeoko

Hello Everyone!

I use a Shapeoko XXL. I am wondering the largest cutting diameter “bottom cleaning” router bit that can be used? I have some plunge cuts that are large is surface area and using a 1/4" diameter takes forever.


I presently am using a 1.312" (33mm) diameter cutter.


This link may help.


This is the end mill I use. It does well and leaves a great finish.
