I must have erased the Easel file for drilling out the holes. I would suggest a plunge rate of 2/3 recommended since you’re going to effectively be drilling instead of milling. Can’t find my CNC journal to give you any examples, so I would keep the feeds and speeds consistent with what you would use on MDF with the bit you’re going to use. I’d recommend an upcut bit, to help remove the dust and save your bit from dulling.
