Been machining for a living for 18 years. One off and small runs. Been there, flood coolant, mist spray and now unless I'm doing steel or heavy aly, I have reverted to a 5 cc syringe with a thin needle and I spot the material or cutter as it runs with neat cutting oil. If I'm surfacing a plate or machining around a big block, I put a few drops of cutting fluid on it and then smear it with a 1.5 inch paint brush.
I think I have said this before, but, Castrol Ilocut 154 (think mine was called 64 when I bought a 20 litre drum 25 years ago and still using it daily) is a neat cutting oil that is fantastic. If I skim 2 bits of aly, one dry and one with oil, I can easily see the difference. Drip oil with deep pockets and then remove the swarf with compressed air. Running the mister all the time makes every thing sticky. I never mill aly without fluid. Aly friction welds to easily. Aliexpress, 20 syringes with needles for a couple of $$ I now have syringes next to the drill press, mill and lathe. I still use flood with steel if I have to remove heat. Flood if you have a fully closed in machine. Still use HSS for plastics. Seems to cut the best.
