When using the bore option in Fusion 360, what is the recommended endmill size to hole size?
Specifically, for a 3.3mm diameter hole, is a 3.175mm diameter endmill small enough? It seems Fusion lets me generate the toolpath, but is there enough of a difference in the diameters?

In addition, that last topic I saw when searching the internet was that, for boring holes, conventional cut with only 1 pass gave the best holes. Is that recommendation still applicable today with a Shapeoko 3 and HDZ?
Edit: So it figures, just after posting this, I found a Winston Moy video where he recommends a 10% difference. I’m not sure if that is material independent as in the video he was working with wood
