Neat cutting
Neat cutting oils
Non-water-miscible neat cutting fluids used for specific applications like tool grinding, gear machining, spark erosion, threading, honing, finishing, lapping and deep hole drilling. Molylub CutOil series innovative non-water-miscible neat cutting fluids influence on the process and the quality of the machined parts, but also make a major contribution to the safety and working conditions in the production halls.

Non-soluble Molylub CutOil oils
Non-soluble Molylub CutOil product series are comprised of cutting fluids designed with highly refined mineral or synthetic oils or high-quality esters. They ensure an increase in productivity, a long life of the product in circulation, and allow to reduce the tool’s wear, preventing the piece, tool, or machine from rusting.
Neat oils for metal cutting operations
Non-soluble Molylub CutOil Bio product series are formulated with biodegradable vegetal or synthetic oils, becoming an environmentally friendly range based on non-polluting additives. Bio Ester-based and low viscosity. Recommended for machining and microspraying operations cast iron, steel and stainless steel. Recommended for medium and high requirement processes.
