ASTRO-CUT BCL LF

ASTRO-CUT BCL LF

Product & Safety Datasheets

Overview

ASTRO-CUT BCL LF is a low foam heavy duty BIOSTABLE semi-synthetic general purpose metalworking coolant containing approximately 20% mineral oil. This product, when diluted with water, forms a translucent amber emulsion which offers excellent workpiece visibility, good lubricity, very low foaming and superior cooling. ASTRO-CUT BCL LF is designed for the machining and grinding of virtually all metals, except magnesium, and contains chlorine as an extreme pressure additive for greater lubricity.

Applications

ASTRO-CUT BCL LF is designed for use in metal removal operations such as all CNC milling, turning, drilling, tapping, and grinding. ASTRO-CUT BCL LF is also excellent on conventional machining processes and sawing applications.

When mixing coolant, it is best to use an automatic proportioner which accurately and thoroughly mixes coolant. To maintain recommended concentration, make-up or top-off should be added at one-half of the desired concentration. Never add concentrate directly to the machine; this could cause inverted emulsions.
