Just a note on the mist coolant. Normal soluble, semi and full synthetic coolant that are designed for flood coolant should never be used in a mist system. Some are chlorinated and are definitely a hazard to breathe. There are mist coolants designed specifically for the purpose, and they don't linger in the air as long as the flood type, nor are they considered hazardous on the lungs. I use a mist system at times, and use Kool-Mist brand coolant. No problems with it.
