TRUEGARD Cutting Oil D Plus - 275 Gallon Tote

It is formulated for machining difficult metals where a high level of active anti-weld protection is needed. However, it may stain non-ferrous metals such as copper, brass, or aluminum, so extra caution or an alternative product should be considered for those materials.

Active sulfur reacts with the metal surface under the extreme pressure and heat of cutting to prevent micro-welding and tearing, and it provides superior control of built-up edge on tools. The inactive sulfur and chlorine contribute additional lubricity without the same surface reactivity, together delivering a more complete performance package for demanding operations.

The anti-mist additive reduces the formation of airborne oil droplets during high-speed machining, which helps limit operator exposure to oil mist and keeps the work area cleaner compared to cutting oils without this feature.

In standard applications it is not suitable as a machine lubricant. However, its dual-purpose formulation makes it appropriate for use as both the machine lubricant and for low-pressure hydraulic systems specifically in automatic screw machines, where significant cross-contamination from lube oils is common.

By combining active sulfur, lubricity agents, and inactive sulfur and chlorine, the oil prevents welding and tearing at the tool-workpiece interface while controlling built-up edge formation - both of which are leading causes of premature tool wear and degraded surface finish.

Based on its formulation as a dark amber, sulfur- and chlorine-bearing active cutting oil - and its noted compatibility with machine lubrication and low-pressure hydraulic systems - this is a straight (neat) cutting oil intended for use as-supplied, without water dilution.
