A cutting lubricant is a fluid or compound applied to the cutting area during machining operations, such as band saw cutting or milling, to reduce friction, dissipate heat, and facilitate chip removal. Cutting lubricants can be oil-based, water-based, or synthetic, and may be applied as a liquid, paste, or aerosol, depending on the specific application and material being cut. Proper use of cutting lubricants can improve cutting performance, extend tool life, and prevent workpiece damage.
