I've seen this topic asked before, but I can't find a definitive answer.
I'm working on a picture frame project where the work piece needs to be cut on both sides.
Because of that, after I cut one side, I need to flip it and do the other.
For that, I'll drill two holes in my spoil board and place a 3/8" dowel in each, then drill two holes
in my work piece so it's correctly aligned.
In VCarve, added the holes and used a 1/4" UC EM to create the 3/8" hole,
but it left a core. I could use a 1/4" twist drill, but the
hole is too small and that size dowel is not sturdy enough.
I have a 3/8" forstner bit with a 1/4" shank, but I don't feel
comfortable using it in my router.
So, how can I drill or cut a clean 3/8" hole?

Re: Hole Drilling
Don't use the "Drill function" for that. Make the hole a Pocket cut (inside a 3/8" diameter vector circle) or a Profile cut (inside the circle).

I'd use a Profile Toolpath with a 1/4" EM, Inside Machine Vector and Spiral ramp.

Re: Hole Drilling
Amana Tool #51694 but you'll need a 3/8 collet for it.

Re: Hole Drilling
Why is a 1/4 dowel not sturdy enough? I use 6mm dowels all the time for double sided work, they are simply for alignment so they don't need to be sturdy
I tend to use 3 dowels rather than 2 with 2 there is still a small risk of movement (depending on job size) but then I am a belt & braces type of person

Re: Hole Drilling
Finding this 2 yrs later on a search on how to drill - this works really well. I needed a series of 1/4" holes and used a 1/8" compression EM bit set up as you suggested. Works perfectly. You'd think the drill function would be how to do it, but nooooo... at least not with an EM.
