Solcut QLB2 is a versatile solution suitable for a broad spectrum of applications. Whether you’re engaged in brass and aluminum machining within large transfer systems or tackling steel machining in smaller, single sump machines, Solcut QLB2 has you covered.

This semi-synthetic biostable machining and grinding fluid forms transparent emulsions, which can become semi-translucent when used with hard water. Solcut QLB2 brings together the cleanliness and detergency typically associated with synthetic products while avoiding the sticky residues often encountered with such alternatives. It’s a reliable choice for various machining operations.


Use Solcut QLB2 at concentrations varying between 2% and 5% depending on the machining application but in general grinding is satisfactory at 2% concentration and other machining applications require between 3% and 4% concentration. For brass machining, good results have been had at concentrations of 6% and for aluminum 10%.


  • Solcut QLB2 emulsions are non-staining when used with aluminum, preserving the material’s appearance.
  • Provides excellent corrosion protection for ferrous materials.
  • Enhances cleanliness and extends the lifespan of the fluid in the sump.
  • Under normal operating conditions, around 90% of any tramp oil present in emulsions with Solcut QLB2 will separate and float to the surface during a weekend shutdown. This facilitates easy removal of tramp oil and further extends the emulsion’s sump life.
  • Like other biostable cutting fluids from Vesta, Solcut QLB2 emulsions can be easily treated with conventional effluent treatment techniques, minimizing disposal costs and environmental impact.


Solcut QLB2 is compatible with most commonly used polymer hose and seal materials. However, due to the wide variety of materials available, specific recommendations should be sought from your distributor or Vesta representative.


If the following criteria are adhered to, Solcut QLB2 can be stored for at least six months.

Maximum recommended long-term storage temperature:                                                                                                40°C. Minimum recommended long-term storage temperature:                                                                                                  0°C. Keep drums/containers tightly closed when not in use.

Store containers/drums in a dry and well ventilated area.

Vesta suggests that the equipment manufacturers’ recommendations for performance requirements and general operating conditions should be checked prior to use.
