Product & Safety Datasheets


ASTRO-CUT HIGH PRESSURE HD is a heavy duty BIOSTABLE semi-synthetic high pressure metalworking coolant. ASTRO-CUT HIGH PRESSURE HD combines the superior chemical flexibility of synthetics with mineral oil and a chlorinated extreme-pressure additive. ASTRO-CUT HIGH PRESSURE HD has exceptional foam control, hard water stability and tramp oil rejection. It provides outstanding extreme-pressure lubricity for machining and grinding virtually all metals, particularly Aluminum, Stainless Steels and other hard to machine alloys. ASTRO-CUT HIGH PRESSURE HD is not recommended for use on Magnesium.


ASTRO-CUT HIGH PRESSURE HD is designed for use in high and low pressure metal removal operations such as all CNC milling, turning, drilling, tapping, grinding and sawing.
