HOCUT 4940 is recommended for heavy duty machining of a wide range of aerospace materials including aluminium alloys (series 2000 and 7000 in particular), high alloy steels and difficult aerospace materials such as titanium and nickel
alloys.
The product is suitable for both centralised systems and single-sump machines while the advanced boron-free technology extends emulsion life without the need for regular biocide treatments. The versatile formulation is designed to give low foam in soft water.

High lubricity: sophisticated package of mineral oil and polar additives extend tool-life
Very long sump-life: new Hocut 4000 series emulsion technology extends intervals between clean outs
Very stable emulsion: fewer additive treatments and lower usage costs
Inhibits aluminium staining: can be used for sensitive alloys eg 7000 series
Very low foaming: ideal for the highest speeds and pressures in soft water
Boron, formaldehyde, chlorine and Phenol-free: excellent EHS profile
