Metalworking Fluid Premium MHDM is a water emulsifiable fluid concentrate for general machining e.g. turning, milling,
drilling and sawing of cast iron, steel, high-alloy steel and aluminium.
Thanks to its specially chosen top grade emulsifier system, modern technology and excellent lubricity additives, the product
is highly versatile. Metalworking Fluid Premium MHDM works particularly well in both soft and hard water.
• free from boric acid, amine containing
• polar lubricity improvers and tight control of the in-use pH achieve optimum results when machining aluminium
Properties / advantages:
• good technical stability
• produces stable emulsions in make-up water from 10 °dH to 30 °dH; emulsion in use is stable up to 60 °dH
• good cooling and detergency properties
• a universal metalworking fluid for both freestanding machines and central systems

Correct preparation of a fresh emulsion 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:
Machining of cast iron, steel and aluminium: from 6 %
Medium to heavy-duty machining: from 8 %
The concentration of the in-use emulsion may be checked using a refractometer. The refractometer reading must be
multiplied by the refractometer factor to arrive at the concentration.
Based on current knowledge Metalworking Fluid Premium MHDM could be used for processing of most aluminium
alloys. However the tendency of the alloy to stain should be checked in advance.
Where necessary, the compatibility of the emulsion with yellow metals may be improved by the addition of DELTA MS
Shelf life / storage conditions:
stable for 12 months when stored at a temperature of 5 °C to 40 °C in unopened containers
Minor variations in colour and appearance are possible due to the raw materials chosen. However, these have no influence
on the functionality of the product.
All information on safe and proper handling can be found on the MSDS or in the instructions for use.
