Threading paste Defender Zoom / Cutting fluid for tapping and drilling

What is Defender Zoom

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.
