Manufacturers seeking outstanding cutting performance and improved tool life now have a proven solution with
Oemeta’s Estramet S95. The new coolant is a translucent, water-miscible metalworking fluid based on synthetic ester technology that is transforming how companies approach demanding operations on difficult materials.
Described as a true ‘all-rounder’ with excellent performance on everything from turning and milling to drilling, threading, honing and grinding, Estramet S95 is said to be a sustainable high-performance coolant that delivers superior lubrication characteristics. Completely free from mineral oil, boron, formaldehyde, fungicide, and active sulphur, Estramet S95 puts employee and environmental welfare first.
Perfect for demanding machining operations on high-alloy steels, stainless steels and aluminium alloys such as titanium and Inconel, the new cutting fluid delivers sustainability credentials without compromising on performance or cost-effectiveness.
Traditional mineral oil-free coolants, particularly polymer-based alternatives, often struggle to match the lubricity and tool life performance of conventional products. However, Estramet S95 breaks this boundary its advanced synthetic ester formulation.
Tooling cost challengesWith carbide prices reaching unprecedented levels and cutting tool costs escalating, Estramet S95 is a simple solution to halt the impact of rising tooling costs. With carbide tooling costs climbing by more than 25%, the tool wear reduction characteristics of Estramet S95 through its ester technology have proven to reduce tool wear by more than 25%. This new product counteracts the cost challenges of cutting tools while reducing the environmental impact of machining operations.
At the heart of the cutting fluid’s performance is its high-performance ester oil base – making it better for staff, the environment and the shopfloor. Unlike standard ester coolants, the formulation provides superior lubricity even at lower oil concentrations.
For manufacturers, there are a multitude of operational benefits. The low oil content significantly reduces drag-out and carry-out on components, translating to lower consumption rates and extended sump life. Despite the reduced oil loading, tapping torque analysis consistently demonstrates the lubrication performance exceeds alternatives with much higher oil content.
The translucent, semi-transparent appearance provides immediate visual feedback on sump condition and contamination levels, making maintenance monitoring straightforward. This clarity, combined with outstanding stability, contributes to a service life that exceeds competing products.
The formulation maintains its performance characteristics with outstanding foaming resistance that ensures consistently high performance.
Estramet S95 excels in demanding operations, including deep drilling and reaming, where consistent lubrication and effective chip evacuation are critical to component quality and tool life. Its pH value of 9.3 at 5% concentration provides outstanding corrosion protection, with corrosion test results meeting the stringent K0 4.0 classification under DIN 51 360/2.
One of the most valued characteristics is its exceptional washing power. Components emerge from machine tools noticeably cleaner than with conventional coolants, frequently eliminating the need for subsequent washing cycles. This removes an entire process step from the production sequence, reducing both cycle time and environmental impact. Machine sumps and work areas remain cleaner, reducing maintenance requirements and improving the working environment.
For manufacturers operating lights-out machining, the fluid combines superior lubricity and low consumption characteristics, which means machines can run extended periods without interruption.
Tramp oil rejection characteristics represent another operational benefit. The synthetic ester emulsifiers effectively separate hydraulic oils that inevitably enter coolant systems. This prevents smoking and burning issues that can effect facilities running conventional coolants with poor tramp oil rejection.
Estramet S95 is supplied as a concentrate with a density of 984kg/m³ and a kinematic viscosity of 51mm²/s at 40°C. The recommended concentration range of 5 to 15% provides flexibility to optimise performance for specific applications, with higher concentrations available for particularly demanding operations.
The product's refractive index of 1.437 enables straightforward concentration monitoring using standard refractometers.
Estramet S95 is particularly suited to manufacturers seeking to balance sustainable machining with improved workplace conditions and machining performance, with Oemeta presenting a product that targets productivity gains rather than competing on price per litre.
For manufacturers processing aerospace, automotive, or medical components where tolerances must be maintained over long cycles, Estramet S95 is said to deliver measurable benefits in both productivity and component quality.
