Zeal Rock Drill oil series of lubricants are supreme performance Pneumatic Rock Drill & Tool oils, formulated with high quality base stocks fortified with sulfur-phosphorus additive system. They are designed to work efficiently in pneumatically operated rock drills in underground and surface mining operations. They offer optimum adhesiveness and emulsification with water to avoid adverse effects of rust and corrosion. Their excellent wear protection property helps in reducing component wear and maintains adequate lubrication film to carry high loads.
Product Description & Specifications
Features & Benefits
