I use a brass tube for making holes in balsa. Sharpen the inside of one end of the tube with an exacto knife. Drill out 1/8'' deep at a time, cleaning the tube every 1/8''
Kinda hard to chuck 5/8" brass tube into a 3/8" drill chuck....
You can make yourself an entire set of balsa bits using brass tubes. I use dowel rods inside and turn or sand one end down to fit my drill press chuck. Simple, cheap and works great.
