ARCCUT® AM445 Low-Oil Semi-Synthetic Coolant
Low-oil semi-synthetic formula with excellent cooling and lubricating properties, extended service life, and reduced overall machining costs.

Product Overview
ARCCUT® AM445 is a low-oil semi-synthetic coolant from ARNOCO. Formulated with mineral oil base stocks and synthetic esters, it leverages advanced emulsifiers and additive systems. This product maintains the superior cooling performance of semi-synthetics while reducing mist and residue through its low-oil formula.
The specially optimized antimicrobial formula extends product life, ensuring the fluid remains fresh and odor-free for 12-18 months under normal maintenance. Suitable for turning, milling, drilling, and grinding operations on steel, cast iron, aluminum alloys, copper alloys, and other metals. Ideal for centralized coolant systems and high-volume continuous production environments.
Core Advantages
Low-oil semi-synthetic formula
Scientifically balanced blend of mineral oil and synthetic esters to optimize lubrication and cleaning while minimizing oil residue buildup.
Superior Cooling Performance
Excellent thermal conductivity and flowability; rapidly dissipates cutting heat to prevent workpiece thermal deformation.
Ultra-long service life
High resistance to corrosion; lifespan of 12-18 months under normal use conditions, reducing total cost of ownership.
