Coastal Premium Rock Drill Oils are blended from highly refined base oils and special additives which produce an outstanding lubricant for air powered equipment. The naturally high viscosity index provides optimum lubrication for both low start-up temperatures and high operational temperatures. Extreme pressure additives prevent wear and withstand the high loads commonly encountered in rock drills, jack hammers, pavement breakers, and down hole drills both in the construction and mining industries and other pneumatic equipment.
