			I only drilled the center part of the nozzle for the water. I used about 4 drill bits and gradually went up in size. Did it all by hand cause they are so small i didnt want them to break off in the tip.i bought a set of like 10 bits. The largest size you need is just under 1mm. So if you get a set of 1 mm and under you should be good.
