What cutting fluid is used for turning graphite?

It is recommended to use fully synthetic cutting fluid, because fully synthetic cutting fluid does not contain oil, so it will not stick graphite dust together to produce sludge, and the water-based cleaning performance is good, which will not cause the equipment to feel dirty. If cutting fluid is not used, the tool will be seriously worn in the process of machining graphite. If oil is used, graphite dust will absorb a lot of oil, causing unnecessary waste.
