| | Cutting Fluid Types |
| |
| Straight oils | Not mixed used straight |
| Mineral oils, | Petroleum based mineral oils are used in light duty machining where cooling is not a factor. Extends tool life and improves surface finish, good rust inhibitor |
| Fatty oils | Animal fat based oil used in medium duty machining where cooling is not a factor. Extends tool life and improves surface finish recommended for tapping and threading |
| Soluble oils | Concentrate mixes with water |
| Mineral Based | Suited for high speed machining where cooling is a factor improves surface finish and tool life, good rust inhibitor |
| Fat Based | Suited for high speed machining where cooling is a factor improves surface finish and tool life |
| Synthetic oils | Water based no minerals or animal fat |
| True Solution | Rapid heat removal, good rust inhibitor, recommended for grinding, poor lubricant leaves sticky residue on work and machine after water evaporates |
| Wet Solution | Rapid heat removal, good rust inhibitor, recommended for grinding, better lubricating leaves no sticky residue |
