Welcome to our combined EZ-Kool and Koolit Metalworking fluids Store. Other Synthetic and Semi-Synthetic Metalworking coolants contain at least 50% to as much as 80% water. Our Super Concentrates ships WITHOUT the water component which saves you money. EZ-Kool allows you to buy the amount of coolant that fits your budget. Choose our EZ-Kool brand for conventional strength 10:1 - 20:1 ratio coolants. Choose our Koolit brand 2X concentration 20:1 - 40:1 ratio coolants to save on freight. This series is like two pails or drums in one! Check out our unique methods and save!
