Featuring excellent extreme pressure, anti-wear, and adhesive properties, it provides stable lubrication protection under high-impact conditions and extends equipment service life.
Rock drill oil is a high-quality heavy-duty lubricant specially designed to provide corrosion protection for rock drills and pneumatic tools under harsh operating conditions. It offers excellent anti-foaming properties and strong adhesion, enabling it to cling to high-speed pneumatic tools. With extreme pressure performance, it withstands the strong impacts generated during rock drilling, ensuring adequate lubrication. It protects critical parts of both rotary and impact drills, preventing wear and scoring. With superior extreme pressure, anti-wear, and adhesive properties, along with good thermal and oxidation stability, it effectively protects pneumatic machinery and extends service life.
