I think too many people just suggest a 2mm bigger hole as a norm.
There is no norm.
Get the bulb in hand and drill then or have the knot prior to making the handle (best option and the one I use). I like to drill the hole then turn the handle.
As mentioned I like to have to push fit a knot, not just drop it in.
Also mentioned was the same knot was reinserted into a 7/8 hole for much better functioning brush. That's a lot of epoxy to make up for a sloppy hole.
