Dowel holes reamer or interpolation?

Nothing great but thanks for the compliment.

you right that you risk making the hole conical. but that is why you would run a number of spring passes. Personally I do not like to run slot mills in plunge mode as you get birdnesting even if you peck drill. With 2-3mm endmills though you are correct, if you do not need to have an accurate position, spot, drill, ream.
