Tired of moving the coolant nozzle to stay with various tools on a production part, I was looking for a quick-n-dirty, not to mention cheap, method of directing coolant where I want it. Poking around in my packrat treasure vault, I found some 5/16 plastic balls. No idea where I got them or what they are made of, but they fit just fine in 1/4" compression fittings (sans the ferrule of course). Drill a through hole, viola. A short length of 1/8" brass tubing allows easy pointing without tools. Drill the hole a touch larger and a short length of the same tube slides in temporarily to assist in aiming. First one I made up has about 1" of tubing extending from the nut. With just finger tightening, it locks tight enough to almost bend the tube before the ball slips. Just eyeballing it, looks like not quite 30 degrees of angle obtainable, more if I bevel the nut on the outside. Fittings are $1.49 each at the local hardware store, the plastic balls can probably be had cheap from McMaster.
