Glass cutting oil is a specialized lubricant used during the process of cutting glass. It helps reduce friction between the cutting tool and the glass surface, allowing for smoother and more precise cuts. This oil also helps to cool the cutting tool, preventing it from overheating and prolonging its lifespan. In addition to improving cutting efficiency, glass cutting oil can also minimize the risk of chipping or breaking the glass. It is typically applied directly to the cutting area before using a glass cutter, ensuring a clean and accurate score line for easier breaking along the desired path.
