DiaMill HEF 1100 from oelheld is a high-performance product based on hydrocrack oils. It has nearly no odor, has high shearing stability, is extremely resistant to aging, and is physiologically safe (no aromatic content). DiaMill HEF 1100 does not contain chlorine or any heavy metals. Its good viscosity/temperature relationship guarantees maximum flushing and cooling properties over a wide temperature range.

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

Its extremely 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 reportedly the ideal alternative to water-soluble cooling lubricants for turning, milling, drilling, hobbing and cutting operations in CNC machining centers. DiaMill HEF 1100 is especially designed for use with high alloyed steel, cast iron or nonferrous metals.
