Missile Lube 5 EH is a hybrid water-soluble concentrate that combines vegetable oil, synthetic oil and mineral oil for lubricity. The coolant is designed to serve many applications and material types. The primary applications are boring, reaming and deep hole drilling of aluminum alloys. Because of the lubricity, the coolant can be used at lower concentrations than conventional oil-based coolants, according to the company. The coolant, says the company, has helped some companies switch from using straight cutting oils while still achieving the required surface finishes.
