Thanks to its synthetic formulation, the fluid remains highly stable and helps prevent biological deposits from forming within the system.

Technical Specifications

Why Choose Defender Ultra

Selecting the correct metalworking fluid is not only about cooling performance. In practice, machine condition, coolant stability, system cleanliness, ease of maintenance, odour control, foaming behaviour, microbial resistance and corrosion protection are all equally important.

Defender Ultra has been developed specifically for these requirements. It delivers not only effective cutting-zone performance but also stable, predictable system operation over time.

Key Properties

Excellent cleaning performance

Defender Ultra ensures cleaner machine operation compared with conventional oil-based emulsions. This is essential where cleanliness, visibility, reduced deposits and easier maintenance are required.

Corrosion protection

The product contains a functional corrosion-inhibiting package that helps reduce corrosion risks on both machine components and workpieces when correct concentration and application procedures are followed.

High biostability

One of the most common issues in coolant systems is microbial growth, unpleasant odour, and fluid degradation.

Defender Ultra is formulated for high biostability and maintains performance when concentration and system hygiene are properly controlled.

Stable working solution

Its synthetic nature ensures a stable solution without the instability commonly associated with emulsion-based coolants.

Balanced performance

Defender Ultra provides a balanced combination of cooling, lubrication and cleanliness, making it suitable for a wide range of machining operations.

The Cutting fluid Defender LIGHT / Coolant-lubricant fluid Defender LIGHT message appeared first on Novohim.

Defender Pro is a premium semi-synthetic water-miscible metalworking fluid for mechanical metalworking operations. The product is supplied as a concentrate and, after mixing with water, forms a working solution for turning, milling, drilling, grinding, boring, honing, bandsaw cutting, and other metalworking operations.
The main feature of Defender Pro is its high content of functional components and high oil content. It is not a “light” synthetic fluid and not a standard entry-level emulsol. It is a higher-grade semi-synthetic metalworking fluid intended for cases where the following are required:

• enhanced lubricating properties;
• better tool protection;
• clean machining and good surface finish;
• stable operation on modern equipment;
• suitability for more heavily loaded conditions than standard universal products.

What Defender Pro is

Defender Pro is a semi-synthetic metalworking-fluid concentrate with a high content of functional components. To understand the product logic, it is important that it contains a very large share of an active functional system, including mineral oil, fatty-acid soaps, and other functional components that form its lubricating, cooling, cleaning, anticorrosion, and operating properties.
That is why Defender Pro occupies a different position from low-cost basic emulsols or light synthetic products. It is a metalworking fluid for more demanding tasks where a balance of lubricating properties, stability, machining cleanliness, and tool life is required.

What class Defender Pro belongs to

Within the economy — standard — premium classification, Defender Pro belongs specifically to the premium class.
This means it is not focused on the lowest concentrate price, but on more demanding working conditions where the following matter:

• enhanced lubricating properties;
• working-solution stability;
• low foaming;
• use on modern machine tools;
• surface quality;
• machining cleanliness;
• long working-solution life when the system is properly maintained.

What Defender Pro is used for

Defender Pro is used for:

• cooling the tool and workpiece in the cutting zone;
• reducing friction between the tool and the metal;
• reducing cutting-tool wear;
• improving machined surface quality;
• stabilizing the cutting process;
• providing corrosion protection for equipment and parts;
• operation in machine systems with low, medium, and part of high-speed machining conditions.

Where Defender Pro is most appropriate

Defender Pro is most appropriate where the following are required:

• a semi-synthetic metalworking fluid with high oil content;
• enhanced lubricating properties;
• machining of stainless steel, high-alloy steels, cast iron, aluminum, and its alloys;
• use on CNC machines, automatic and semi-automatic equipment;
• stable operation under heavier conditions than standard universal emulsols;
• low foaming;
• long working-solution life without constant corrective additions.

The product is appropriate for use in:

• machine building;
• production of stainless-steel parts;
• production of agricultural machinery components;
• metalworking shops;
• modern CNC equipment;
• general-purpose machinery where not just basic but enhanced lubricating properties are required.

Suitable materials

Defender Pro is suitable for machining:

• carbon steels;
• alloy steels;
• high-alloy steels;
• stainless steels;
• cast iron;
• aluminum and its alloys.

The phrase “for all grades of steel, including super-hard grades” should not be used as an absolute claim. A more correct phrasing is: the product is suitable for a wide range of steels, including high-alloy and difficult-to-machine grades, but actual performance always depends on machining conditions, tooling, the specific operation, and the correctly selected concentration.

What machining conditions Defender Pro is intended for

Defender Pro is designed for a wider range of operating conditions than classic oil-containing standard-grade emulsols. It can be used:

• on low-speed machines;
• in medium-duty conditions;
• in part of high-speed machining conditions where a combination of cooling, lubricating properties, and solution stability is required.

This does not mean the product is equally suitable for any extreme machining condition without limitations. But in the premium semi-synthetic metalworking-fluid segment, Defender Pro has a strong position exactly where standard emulsols are already weak and light synthetics may fail to provide the required lubricating effect.

Main properties and advantages of Defender Pro

Main product properties:

1. semi-synthetic water-miscible metalworking-fluid concentrate;
2. high oil content;
3. high content of functional components;
4. enhanced lubricating properties;
5. low foaming;
6. suitability for more difficult operations and more heavily loaded conditions;
7. good machined surface quality;
8. clean part surfaces after machining;
9. stable working-solution life under proper operation;
10. corrosion protection;
11. suitability for modern equipment, including CNC machines.

One point should be emphasized separately: Defender Pro is not just a universal fluid, but a product with a strong focus on lubricating performance. This is what makes it effective for stainless steels, high-alloy steels, cast iron, and other materials where ordinary products may work less effectively.

What high oil content and high functional-component content provide

The high oil content and strong functional system in Defender Pro provide several practical effects:

• better boundary lubrication;
• lower tool wear;
• better surface quality;
• more stable performance in difficult operations;
• better suitability for steels and stainless materials;
• a higher working level compared with basic semi-synthetic or low-cost emulsion products.

This does not mean the product automatically outperforms any imported equivalent. A more accurate statement is: within its class, Defender Pro is designed for a high working level and can successfully compete with expensive products where lubricating performance, machining quality, and long solution life are important.

Practical operating experience with Defender Pro

In stainless-steel machining

In production trials, Defender Pro showed:
• high machining quality;
• good lubricating properties;
• stable working-solution performance;
• long service life in the system when concentration was controlled and operating practice was correct.

In production of agricultural machinery parts

Under production conditions, Defender Pro showed:
• reduced tool wear;
• high cleanliness of the machined surface;
• stable operation without pronounced foaming problems;
• long working-solution life without constant addition of corrective components.

On a bandsaw machine

During production trials on a bandsaw machine, Defender Pro showed a significant increase in saw-blade life compared with the product used previously. Under specific conditions, blade life was up to 2.5 times longer.
This result is explained by the combination of lubricating properties, working-solution stability, and the correctly selected concentration. The actual effect depends on:
• material;
• cutting conditions;
• blade type;
• machine condition;
• blade tension;
• operating conditions;
• correct working-solution management.
For that reason, this result should be treated as a practical production case, not as a universally guaranteed result for all conditions.

Recommended working-solution concentrations

• Turning: 3%
• Drilling: 4%
• Deep drilling: 5%
• Broaching: 3%
• Gear cutting: 5%
• Rolling and thread cutting: 5%
• Milling: 4%
• Boring: 3%
• Honing: 3%
• Bandsaw cutting: the working concentration should be selected according to actual cutting conditions, material, and machine operating mode.

Recommended concentrations may be adjusted depending on:

• material;
• machining conditions;
• tool type;
• system condition;
• supply method;
• water quality;
• actual operating load.

How to use Defender Pro correctly

To obtain a stable result, the following is recommended:

1. Fill the system with clean water.
2. Add the concentrate to the water.
3. Prepare a working solution of the required concentration.
4. Mix until homogeneous.
5. Supply the working solution to the cutting zone through the coolant system.
6. Check concentration with a refractometer during operation.

Before preparing the working solution, the concentrate must be thoroughly mixed until homogeneous.

Important note on water

The old text says that Defender Pro is easily prepared with ordinary tap water without additional treatment. That wording should not be left as an absolute claim.
A more accurate version is:
Defender Pro can work normally with ordinary tap water in many production environments, but actual water quality still affects working-solution stability, foaming, corrosion protection, and metalworking-fluid service life.
That means:
• it is not as water-sensitive as classic oil-containing emulsols;
• but it is still wrong to claim that water quality does not matter at all.

Storage

Defender Pro concentrate should be stored:

• in tightly closed containers;
• indoors;
• at temperatures from +5 °C and above;
• without freezing;
• without prolonged exposure to direct sunlight.

If you have a real upper storage limit of +40 °C, it is better to keep that as a separate technical parameter in the product card or technical data sheet.

Economics of use

At working concentrations of 3–5%, the cost of the ready working solution is many times lower than the cost of the concentrate. This is one reason why Defender Pro may be economically justified even when the concentrate itself is more expensive than simpler products.
The product should be evaluated not only by the price of the canister or drum, but by:
• solution life;
• tool wear;
• surface quality;
• consumption;
• system stability.

When Defender Pro may not be the best choice

Defender Pro should not be presented as the only correct product for all tasks.
In other cases, the following may be more appropriate:
• synthetic metalworking fluids, if the main criteria are system cleanliness, lower oiliness, and higher operating stability;
• specialized products for non-ferrous metals, if the main task is copper, brass, or bronze;
• narrowly specialized formulations, if the application involves extremely heavy conditions requiring special EP lubrication.
The strength of Defender Pro is not in a slogan like “for everything,” but in the fact that it is a premium semi-synthetic metalworking fluid with high oil content for serious metalworking.

Conclusion

Defender Pro is a premium semi-synthetic water-miscible metalworking fluid with a high content of functional components and a high oil content. The product is intended for modern metalworking where enhanced lubricating properties, good surface quality, low foaming, stable solution life, and suitability for more heavily loaded conditions than standard emulsols are required.
The product is most appropriate for machining steels, including stainless and high-alloy grades, cast iron, aluminum, and its alloys, as well as for operation on modern equipment, including part of CNC machines. When used correctly, Defender Pro provides not only cutting-zone performance, but also normal overall system stability.
