TRUEGARD Soluble Oil 100 - 5 Gallon Pail

TRUEGARD Soluble Oil 100 is formulated for heavy-duty machining and grinding and fits most cutting operations. Verified users have reported successful use in CNC lathes, vertical machining centers (VMCs), and bandsaws, making it a versatile choice for both large machine shops and individual operators.

A refractometer factor of 1.1 means you multiply your refractometer's Brix reading by 1.1 to get the actual concentration of this coolant in your sump. This correction factor is specific to each coolant's formulation, so using it ensures you're maintaining the correct mix ratio rather than relying on a generic water reading.

The anti-foaming agent prevents foam buildup during high-speed cutting, which can otherwise impair heat dissipation and lubricant delivery to the cutting zone. The anti-wear agents reduce tool and workpiece surface wear by maintaining a protective film between metal surfaces under load.

Based on user experience with this product, the coolant does not sour when machines sit idle between uses. The low-volatility, low-carbon formula also minimizes deposit buildup in the sump and on machine components during downtime.

A low-carbon formula means fewer residue deposits accumulate on machine surfaces, slideways, and coolant passages over time, reducing cleaning maintenance. Low volatility means the coolant does not evaporate quickly from the sump, helping maintain a consistent mix concentration during operation.

Yes, TRUEGARD Soluble Oil 100 contains corrosion inhibitors that protect both ferrous and non-ferrous machine components and workpieces. This protection is particularly important for coolant sumps, machine ways, and freshly machined part surfaces that are vulnerable between operations.
