During machining, Defender Ultra forms a stable working solution that simultaneously cools the cutting zone, reduces friction and efficiently removes chips.

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 Lubricant-coolant fluid Defender Standard / Cutting fluid Defender Standard message appeared first on Novohim.

Defender Zoom is intended primarily for applications where lubricating action needs to be concentrated directly at the contact zone between the cutting tool and the workpiece. Its thick consistency makes local application possible without filling the entire machine circulation system with the product.
The product is water-washable. This is useful when the paste needs to be removed with water after local machining or when the same product is intended for both local application and use as a water-miscible MWF.

Key characteristics

When Defender Zoom is a suitable choice

• thread cutting;
• drilling and deep-hole drilling;
• gear cutting and other demanding local operations;
• applications where a paste is required for brush application or direct application to the tool or cutting zone;
• small machine tools where it is convenient to use one product both locally and in the circulation system.

When to consider an alternative

If an MWF is used continuously in a large circulation system, Defender Zoom should be compared with a dedicated circulating fluid such as Defender Pro. Defender Zoom can perform well in circulation, but for larger system volumes a dedicated circulating MWF will often be more economical.
For more severe local machining operations, Master Rez or Defender Oil 210 can also be considered. Defender Zoom differs in that it is water-washable and can be prepared as a water-based working mixture.

Depending on production conditions and customer requirements our specialists will select the most suitable modification Coolant Biol or Defender for drilling, tapping and other heavy metalworking operations.

Application

1. Undiluted paste — primary mode of use
Defender Zoom can be used without dilution. Apply the paste directly to the cutting zone, tool or workpiece. This mode is appropriate when a thick consistency and concentrated local delivery are required.
2. Dilution to obtain a convenient consistency
If the undiluted paste is too thick for the selected application method, Defender Zoom can be diluted with water. At approximately 30–50% product content, a thick paste-like working mixture is obtained, which may be convenient for application with a brush.
The 30–50% range should not be interpreted as the recommended concentration for a circulation system. It is intended as a practical range for adjusting consistency during local application.
3. Use as a circulating MWF
Defender Zoom can also be used as a water-miscible circulating metalworking fluid. The working concentration is selected from 5% upward depending on the operation, machining load and actual system performance.
This approach can be particularly practical for small machine tools and low-volume tanks: part of the product can be used as a paste for demanding local operations, while the remainder can be used to prepare the circulating MWF. For a large system, the concentrate consumption and working-fluid cost should also be compared with a dedicated circulating MWF.

Materials and compatibility

The current Defender Zoom product page lists applications involving steel, stainless and high-alloy steel, cast iron, aluminium, copper, brass, bronze and titanium. This list should not be interpreted as a claim that the product is suitable for every metal under all conditions. The application mode should be selected with regard to the specific material, machining operation, load and contact time.
If the main task is demanding local machining of non-ferrous metals and a different type of product is preferred, Master Rez should also be considered.

Preparation and use

• Before local application, remove excessive contamination from the machining area where practical.
• Apply Defender Zoom directly to the cutting zone in an amount appropriate for the operation.
• To reduce thickness, prepare a mixture with water to the required consistency; approximately 30–50% product is a practical reference range for a thick paste-like mixture.
• For circulation use, prepare the water-based working fluid separately by adding the concentrate to water while mixing.
• Select the initial circulating concentration from 5% upward and adjust it according to machining load and actual performance.

Operation

For local use, make sure that paste remains available in the cutting zone and reapply it when required. When Defender Zoom is used in circulation, monitor concentration, working-fluid condition, system contamination and circulation stability.

Storage and safety

Follow the current product documentation and standard industrial hygiene practices during use. Storage conditions and shelf life are not stated in this version because they require confirmation against the current Defender Zoom documentation.

FAQ

Does Defender Zoom have to be diluted with water?
No. Its primary mode of use is undiluted as a local machining paste. Dilution is used when a different consistency is required or when the product is prepared as a circulating water-miscible MWF.
Why dilute Defender Zoom to 30–50%?
This range can provide a convenient paste-like consistency for local application, for example with a brush. It is not the recommended concentration range for a circulation tank.
Can Defender Zoom be used in a machine circulation system?
Yes. Defender Zoom can be used as a circulating water-miscible MWF from 5% concentration upward, with the actual concentration selected according to the operation and machining load. This can be especially practical for small machine tools and low-volume systems.
Which is better for continuous circulation: Defender Zoom or Defender Pro?
Defender Zoom is primarily a paste for demanding local operations, although it can also be used in circulation. Defender Pro is designed specifically for circulating service, so for large tanks or continuous operation the required concentration, machining result and concentrate consumption should be compared.
How does Defender Zoom differ from Master Rez and Defender Oil 210?
Defender Zoom is a water-washable paste concentrate that can be used undiluted, diluted with water to adjust consistency, or prepared as a circulating MWF. Master Rez and Defender Oil 210 are alternatives for more severe local operations and follow a different application concept.

Ordering and selection

Defender Zoom is a suitable option when one product is needed for local application in drilling, thread cutting and other demanding operations, with the additional flexibility to adjust consistency with water or use the product in a small circulation system.

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.

What BIOL is

BIOL is a concentrated water-miscible metalworking fluid used to prepare a working solution that is delivered to the cutting zone between the tool and the workpiece.
When correctly prepared and maintained, the working solution performs several main functions:

• removes heat from the cutting zone;
• reduces friction between the tool and the workpiece;
• helps remove chips and machining residues;
• supports corrosion protection of metal surfaces.

The performance of a metalworking fluid depends not only on the concentrate itself, but also on the working concentration, water quality, machining conditions, equipment condition and proper system maintenance.

Key characteristics

Long-term industrial use and successive formulation updates have kept BIOL relevant for serial production, maintenance workshops, machine-building plants and metalworking operations.
BIOL can be considered for:

• serial metal machining;
• repair and machine shops;
• machine-building plants;
• production of metal parts and components;
• local metalworking-fluid circulation systems;
• centralized systems where the operating conditions and equipment are suitable.

More demanding materials, severe cutting conditions or special technical requirements may call for a more specialized metalworking fluid.

Machining operations

BIOL is primarily intended for standard machining operations, including:

• turning;
• milling;
• drilling;
• boring;
• threading;
• grinding.

For severe cutting conditions, deep-hole drilling, broaching and other operations with high tool loads, the suitability of BIOL should be checked against the requirements of the specific process.

Workpiece materials

The main application range of BIOL includes:

• carbon and structural steels;
• low-alloy and alloy steels;
• stainless steels;
• cast iron.

For aluminium and its alloys, copper, brass, bronze, titanium and other special materials, the product should be selected with regard to the specific machining operation and surface requirements.
For such applications, a more specialized metalworking fluid from the product range may be a better choice.

When BIOL is a practical choice

BIOL is worth considering when:

• a water-miscible metalworking fluid is required for standard machining operations;
• the plant works mainly with steels and cast iron;
• a balance between working performance and product cost is important;
• there are no special requirements for particularly severe cutting conditions;
• there are no elevated environmental requirements for the formulation;
• the system allows the working concentration and solution condition to be monitored correctly.

Typical working concentration: 5%

The typical BIOL concentration for initial system filling is 5%.
The concentrate is mixed with water in the quantity required to prepare a 5% working solution.
The concentration should not be reduced arbitrarily simply to lower consumption.
An excessively low concentration may reduce:

• lubricating performance;
• corrosion protection;
• stability of the working solution.

Increasing the concentration above the required level does not automatically improve machining performance and increases concentrate consumption.
For typical operating conditions, 5% is the starting concentration.
Why a 2% solution is recommended for make-up
During operation, part of the working fluid is lost with chips and workpieces, while part of the water evaporates.
Water evaporates much faster than the components of the concentrate.
If these losses are continuously replaced with a 5% solution, the concentration of the metalworking fluid in the tank may gradually increase.
For this reason, a 2% BIOL solution is recommended for routine make-up.
A practical approach is:

• initial system filling — 5%;
• monitor the condition and concentration of the working solution during operation;
• use a 2% solution for routine make-up;
• if the actual concentration deviates significantly, correct it based on the measured value.

This principle applies to water-miscible metalworking fluids in general: make-up should take into account both mechanical losses of working fluid and the preferential evaporation of water.

Water quality

Water makes up most of the working solution, so its properties have a direct effect on metalworking-fluid performance.
Excessive hardness, high salt content or other deviations may contribute to:

• deposit formation;
• foaming;
• changes in working-solution stability;
• corrosion-related problems;
• shorter periods of stable fluid operation.

The public product page should not make the absolute claim that BIOL performs identically with water of any hardness.
Before preparing a large volume of working solution, it is advisable to know the main characteristics of the process water used at the facility.
See also the Novohim Reference Centre article on water preparation for metalworking fluids.

Monitoring during operation

The condition of the working solution should be checked periodically.
Particular attention should be paid to:

• concentration;
• unusual odour;
• foaming;
• contamination by chips and sludge;
• tramp-oil contamination;
• deposits in the tank;
• signs of corrosion on parts or equipment.

Concentration can be monitored with a refractometer using the procedure specified for the particular product.

Main limitations

BIOL should not automatically be used:

• for every metal without checking suitability;
• for particularly severe cutting conditions;
• for deep-hole drilling without confirming the process requirements;
• for non-ferrous metals without checking compatibility;
• below the recommended concentration without a technical justification;
• after mixing with a product of unknown composition;
• in a contaminated system without prior cleaning.

Correct metalworking-fluid performance depends not only on selecting the concentrate but also on proper system maintenance.

Storage and safety

Store BIOL concentrate in its tightly closed original packaging in accordance with the conditions specified in the manufacturer’s documentation.
Do not allow the concentrate to become contaminated with foreign substances.
When handling the concentrate and working solution, follow industrial hygiene practices and use personal protective equipment in accordance with the product documentation.

FAQ

Is BIOL supplied ready for use or as a concentrate?

BIOL is supplied as a concentrate. A water-based working solution is prepared before use.

What is the typical BIOL concentration?

For initial system filling, the typical concentration is 5%.

What solution should be used for routine make-up?

A 2% solution is recommended for typical make-up because water evaporates faster than the components of the concentrate during operation.

Why not use a 5% solution for every make-up addition?

If the initial concentration is used for every make-up while water continues to evaporate, the metalworking-fluid concentration in the tank may gradually increase.

Can only water be added?

Adding only water without concentration control is also undesirable. Working fluid is also lost with chips, workpieces and other mechanical losses, so a weaker working solution is used for routine make-up.

Can BIOL concentration be checked with a refractometer?

Yes. The correct procedure and product-specific data should be used. The necessary technical information is supplied separately to customers.

Can BIOL be mixed with another metalworking fluid?

Not without checking compatibility.

Which materials is BIOL intended for?

Its main application range includes structural, alloy and stainless steels, as well as cast iron. Suitability for non-ferrous metals and special alloys should be checked separately.

How does BIOL differ from BIOL Universal?

BIOL is a traditional cost-effective metalworking fluid for common machining operations. BIOL Universal places greater emphasis on modern environmental requirements for the formulation.

Does the working solution have to be replaced after a fixed period?

No. Its condition depends on operating conditions, water quality, contamination, concentration and maintenance. One universal service interval for all systems would be incorrect.
