But it did do what I wanted. The problem was that I needed to through hole tap, and the hole wasn't deep enough. Also, it takes several passes, just like tapping by hand, because of debris buildup.
Consider adding an air nozzle(s) close to the working bit, to move the chips out and away from the hole. You wouldn't need a running compressor while the mill is running, just a decent size storage tank that a small compressor could fill up earlier. A solenoid to actuate the air line at appropriate times, controlled by your CNC system, should do the trick.
