Fully synthetic water soluble grinding fluid for High speed steel grinding in toolroom applications, typically done with a very friable abrasive grain because of the difficulty of grinding these materials.
Molylub SynGrind HS
mineral oil-free, water soluble HS steel grinding coolant concentrate
Molylub SynGrind HS is a water soluble metalworking coolant concentrate for grinding operations of High Speed alloyed and unalloyed steel, sharpening of HSS bits, HSS lathe tools
Due to specially chosen polar lubricity improvers the product can also be used for machining of aluminium and yellow metal.
Product profile:
- free from boric acid, amine containing coolant concentrate
Product properties / advantages:
- improved tool life due to well-balanced additives
- good load carrying capacity
- good filtration properties
Technical data:

Application:
HSS steel grinding, and chipless operations
Remarks:
Correct preparation of a fresh solution is ensured by slowly pouring the concentrate into water while stirring continuously. Alternatively, an automatic mixing device may be used.
The recommended concentration depends on the application and the materials to be machined:
HSS grinding : 7 % – 12 %
The concentration of the in-use solution may be checked using a refractometer. The refractometer reading must be multiplied by the refractometer factor to arrive at the concentration.
When intending to machine aluminium or yellow metal alloys, we suggest checking in advance the tendency of the alloy to stain. When necessary add biocide to the solution in use.
Shelf life / storage conditions:
stable for 12 months when stored at a temperature of 5 °C to 40 °C in unopened containers
Comments:
Minor variations in colour and appearance are possible due to the raw materials chosen. However, these have no influences on the functionality of the product.
All information on safe and proper handling can be found on the MSDS.
