Molub HK is an inactive type of oil used at heavy metalwork operations, such as cold forging, as well as at light metalwork operations, such as cold deformation and punching of all steel types. Contains selected additive package, ensuring extremely high pressure persistence, along with good machining results. It does not have adverse impact to non-ferrous metals, so it can be used for more complex machining of copper and copper alloys. This type of oil provides good cooling and lubrication, resulting in long tool service life.
