Cutting oils and additives cool, lubricate, and help prevent damage to machinery, tools, or workpieces in machining operations. Direct-application cutting lubricants are applied directly to workpieces or cutting tools. Electrical-discharge machining fluids conduct an electrical charge to remove small amounts of material from a submerged workpiece. Cutting oils lubricate parts during cutting, threading, grinding, or milling. Way oils reduce friction between sliding parts to prevent wear and allow them to move smoothly. Machining fluid additives control bacterial growth or foaming that can contaminate machining fluids or reduce their effectiveness. Cutting tool cleaners remove lubricants, grease, and coolants from cutting tools to prevent damage to the tools and extend their life.
