Oemeta ESTRAMET S 77

100% Ester-Based Lubricity
Uses high-performance esters instead of mineral oil to provide strong lubricating film performance for deep-hole drilling and reaming operations.

Aerospace Material Compatibility
Formulated for sensitive aluminum and titanium alloys, helping reduce staining and intergranular corrosion concerns on critical parts.

Translucent Process Control
The semi-transparent emulsion supports clearer visibility of the tool-to-workpiece interface during precision machining.

Mineral Oil & Boron-Free
Free of mineral oil, boron, formaldehyde-releasing agents, fungicides, and active sulfur for a cleaner chemistry profile and modern workplace compatibility.

Extreme Washing Activity
High-detergency properties help keep machine housings and workpieces cleaner by carrying away fine swarf and reducing sticky residue buildup.

Superior Foam Control
Designed for stable low-foam performance, including in softer water conditions starting around 10 °dH, to support consistent cooling in high-pressure systems.

Extended Sump Stability
Provides strong physical and chemical stability to support longer fluid service life and fewer premature change-outs.

Unified Production Strategy
Oemeta ESTRAMET S 77 solves the logistical complexity of high-stakes manufacturing for both specialized job shops and large aerospace facilities. By bridging the gap between heavy-duty cutting performance and environmental safety, it enables plant-wide standardization on difficult materials like Titanium and Inconel. Its ester-based engine provides the lubricity required for deep-hole drilling while maintaining the stability necessary for central systems.

Technological Strength Meets Precision
Represents the pinnacle of modern, water-miscible fluid technology. By replacing mineral oil with a 100% synthetic ester backbone, this fluid eliminates the mess issues associated with traditional coolants. Its mineral-oil-free nature ensures that even the most difficult machining processes are completed without the sticky residues often associated with heavy-duty fluids. Its robust corrosion protection guarantees that high-value aerospace components remain protected throughout the production cycle.
