They require drilling / milling a lot of holes. I was making the holes 1/8" the same size as the end mill which is ok but I think it would be better if they were a little bigger. So what is the better thing to do get a 3/16" bit or instead of drilling them mill them out with the 1/8" end mill?
The other complication is I am using a dremel for the spindle which only will take up to 1/8" so can I even get a 1/8" shank 3/16" end mill?
I used the helical drill command under drill in estlcam. It worked pretty good but not as nice of results as I got from just straight drilling. I saw chipping and out of roundness on the top side of the piece.
Pretty sure for that, you’d need a downcut bit. Though never use a downcut bit to make a hole that’s the same size as the bit. Needs a place for the chips to go.
