NEAT Metal Cutting fluid
Neat cutting oils, sometimes referred to as straight oils, are non-emulsifiable lubricants used in metal cutting and forming operations without dilution. They are typically formulated from highly refined mineral oils, synthetic bases, GTL oils, or biodegradable vegetable oils, and further enhanced with EP (extreme pressure) and anti-wear additives. Unlike water-miscible coolants, neat oils provide superior boundary lubrication at the cutting zone, forming a stable lubricating film that minimizes metal-to-metal contact.
This results in lower cutting forces, reduced tool wear, improved dimensional accuracy, and extended service life of both tools and machines. Due to their excellent thermal stability, oxidation resistance, and high flash points, neat cutting oils are especially suited for demanding operations such as thread rolling, gear hobbing, broaching, deep-hole drilling, and carbide grinding on difficult-to-machine materials, including tungsten carbide, titanium alloys, cobalt-based alloys, cermets, and specialized composites.

At Lubeco, we engineer a complete portfolio of neat metal cutting oils designed to meet the precise demands of modern machining environments. Our formulations combine optimized viscosity profiles for efficient chip evacuation, low-volatility base stocks for safer operation, and additive technologies that deliver superior EP performance, anti-corrosion protection, and minimal residue formation. Available in synthetic, mineral, GTL, and vegetable-based variants, Lubeco’s oils ensure multi-metal compatibility, low mist and smoke generation, and non-staining performance on sensitive alloys. By focusing on both operational efficiency and compliance with global health and environmental standards, Lubeco provides cutting fluids that not only extend tool life and improve surface finish but also enhance overall process reliability in high-precision machining.
