TRUEGARD Cutting Oil D Plus - 55 Gallon Drum

It is formulated for machining difficult metals where a high degree of active anti-weld protection is required. However, it may stain non-ferrous metals such as copper, brass, or aluminum, so it is best suited to ferrous metal applications unless staining is acceptable.

The inactive sulfur contributes lubricity without chemically reacting with the workpiece, while the active sulfur chemically engages at the cutting zone to provide superior control of built-up edge on tools - the condition where workpiece material welds onto the tool tip. This combination prevents welding and tearing, produces better part finishes, and extends tool life on demanding cuts.

The anti-mist additive reduces the formation of airborne oil mist that typically occurs during high-speed machining. This helps maintain a safer breathing environment for operators and also reduces product loss during high-speed operations.

Under normal circumstances it cannot be used as a machine lubricant. However, in equipment with considerable cross-contamination from lube oils - such as most automatic screw machines - TRUEGARD Cutting Oil D Plus is formulated as a dual-purpose oil that can serve as both the machine lubricant and for low pressure hydraulic systems.

Yes. The product is specifically noted for use in automatic screw machines where lube oil cross-contamination is common, allowing it to function as both the cutting fluid and machine lubricant in those environments. A verified customer has also confirmed it performs well in older Brown & Sharpe screw machines.

A Safety Data Sheet (SDS) is available for this product and covers handling, storage, and hazard information. A product specification datasheet is also available. Both documents should be reviewed before use, particularly given the product contains active sulfur and chlorine compounds.
