DiaMill HEF 1100 is a high performance product based on hydrocrack oils. It has nearly no odor, has high shearing stability, is resistant to aging and is physiologically safe (no aromatic content). DiaMill HEF 1100 does not contain chlorine or any heavy metals. 

High performance additives, in combination with interfacial active substances, allow for high-cutting speeds and quality surface finish. Tool life is increased while the formation of a built-up cutting edge is prevented.

Its low tendency towards vaporization and misting results in a high level of safety during use and also in high profitability. This product is not aggressive towards varnishes and elastomers. DiaMill HEF 1100 has a high flash point, greater than 302° F (150° C), even with its low viscosity.

DiaMill HEF 1100 is an ideal alternative to water soluble cooling lubricants for turning, milling, drilling, hobbing, and cutting operations in modern CNC-controlled machining centers. DiaMill HEF 1100 is especially designed for use with high alloyed steel, cast iron, or non ferrous metals.
