DRK Deep Hole Extreme Pressure Cutting Oil 810 Series for Deep Hole Boring Machines

Deep Hole Boring Machine Cutting Oil Product Performance: Deep hole boring machine cutting oil is refined from premium mineral oil with the addition of various extreme pressure agents. This product is a transparent oily metalworking lubricant with excellent lubrication, cooling, and extreme pressure resistance properties. Applications and Scope: This product is primarily used for the cutting processing of ferrous and non-ferrous metals under high-load, low-speed conditions, such as drilling, boring, slotting, gear hobbing, thread cutting, reaming, tapping, and lubrication for specialized gun drilling in high-precision hole making. It can also serve as a lubricant for high-speed metal cutting, scraping, and roll forming processes. Based on different base oils and additives, this product is categorized into several grades, suitable for deep hole processing of ordinary carbon steel, copper, aluminum, stainless steel, titanium, nickel, and other alloy steels.
