QuakerHoughton Aquacut 9/8

A water-mix metalworking fluid designed for the machining of high order steels & alloys


AQUACUT 9/8 is a high performance, long life metalworking coolant with EP properties. It is highly suitable for medium to heavy duty metal cutting operations on a variety of materials including Stainless and High Chromium Steels and Nimonic alloys which have typically utilised neat oils for the more arduous machining operations such as deep hole drilling and tapping.
