So I invested in a coolant sprayer for the lathe that hooks up to the shop air and draws coolant from a container with a flexible plastic hose. Vacuum in the spray head pulls the coolant up to the nozzle. You can adjust the amount of spray with the valve on the unit. I picked up a bottle of water based coolant that is supposed to be good for everything. It was all smiles and chuckles until I read the label on the coolant jug. It is toxic! You are instructed to avoid all contact with skin and eyes. If it touches you a flush with water and trip to the emergency room is recommended. Sheesh. Who are these jokers? This stuff is being sprayed on a rapidly rotating workpiece. It will splash everywhere. I will be coated head to foot in it and breath it to boot. Are they kidding? Is there a better option for a water based coolant? What do people use in these spray systems? Or should I order a HazMat suit and hang biohazard signs on the door of the shop?
