Swiss Silver HM (Hard Metals)

Swiss Silver HM can be provided in both Type A and Type B:

Type A

For all metals, including copper and brass. It can also be used on plastics.

Type B

Contains an additive that increases tool life performance on ferrous metals and tough alloys, but can tarnish brass or copper unless parts are cleaned immediately.


Swiss Silver HM is a combination mineral oil and synthetic base, premium cutting fluid designed for hard-metal machining applications. The unique additive package was developed to migrate to the tool point and coat the tool to maintain the sharp edge and extend the longevity of the tool. It is a bright and clear fluid that affords exceptional visibility while allowing optimum operating speeds and stock removal. The low-foaming qualities and high performance make this fluid ideal for high-pressure coolant delivery systems. Utilizing state-of-the-art technology, Swiss Silver HM excels on stainless steels with high hardness factors, tough high nickel alloys, and titanium. In long-term usage, it provides high performance on all metals. It also out-performs conventional oils previously recommended by machine manufacturers.


The high flash point of Swiss Silver HM provides maximum safety. This fluid will not cause operator skin irritations and is non-hazardous. It contains no nitrites or ethanolamines.


Swiss Silver HM is a clear, low-viscosity mineral oil and synthetic-base oil. The unique formulation of this product results in a low-foam, low-smoke fluid that is cleaner than standard oils used in Swiss-style CNC turning machines. Since it is a clear liquid, it provides optimum visibility for the machine operator.
