3M™ Scotch-Brite™ CG-ZS Non-Woven Wheel

3M™ Scotch-Brite™ CG-ZS non-woven wheel: industrial stripping and cleaning without damaging metal

The 3M™ Scotch-Brite™ CG-ZS non-woven wheel is the reference tool for stripping, deburring, and cleaning metal surfaces in industrial environments.

Its non-woven abrasive acts gently: it removes oxides, rust, and residues without scratching or deforming the metal.

Designed for use on stationary machines, it offers a long service life and consistent results from one piece to the next.

What is the 3M™ Scotch-Brite™ CG-ZS non-woven wheel?

The 3M™ Scotch-Brite™ CG-ZS non-woven wheel is a rotary abrasive tool designed for stripping, cleaning, and finishing metal surfaces in industrial workshops.

It mounts directly onto angle grinders or spindles. Its open structure continuously clears away residues, which limits clogging and extends the tool's lifespan.

At Dagobert Industrie, we recommend it for operations that require a clean result without deforming or marking the base metal.

Scotch-Brite non-woven technology: operating principles

A non-woven abrasive is not a conventional grinding wheel. It consists of entangled synthetic fibers, impregnated with abrasive grains bonded by resin.

Result: the wheel works gently and flexibly. It follows the contours of the part without creating localized pressure points, unlike a rigid disc.

As the surface wears, new abrasive grains are revealed from within. Effectiveness therefore remains constant from the beginning to the end of the wheel's life.

Key advantages of this technology:

• No overheating of the metal: risk of deformation or oxidation minimized
• Homogeneous and reproducible treated surface
• Compatible with steel, stainless steel, aluminum, and non-ferrous alloys
• Generates little fine dust compared to rigid abrasives

Technical specifications of the Scotch-Brite™ CG-ZS wheel

The 3M Scotch-Brite™ CG-ZS wheel is a non-woven wheel designed for stripping, deburring, and cleaning metal surfaces without attacking the base metal.

It is manufactured from non-woven synthetic fibers impregnated with abrasive grains. This open structure prevents clogging and dissipates heat better than a conventional abrasive disc.

The grain used is zirconia alumina (ZS), known for its controlled aggression and longevity. It is particularly suitable for stainless steels, carbon steels, and alloys.

Main areas of application:

• Removal of rust, mill scale, and oxides
• Stripping of welds and weld beads
• Surface preparation before treatment or painting
• Cleaning without changing the geometry of the part

Here is how the CG-ZS positions itself against other common non-woven wheels:

Product	Abrasive	Aggression	Main usage
3M Scotch-Brite CG-ZS	Zirconia alumina	High	Stripping, steel/stainless deburring
3M Scotch-Brite CG-AS	Aluminum oxide	Medium	Finishing, light surface cleaning
Mirka Mirlon non-woven wheel	Aluminum oxide	Low to medium	Wood and metal finishing
Norton Bear-Tex wheel	Aluminum oxide / SiC	Medium	Cleaning and satin finishing

The non-woven structure of the CG-ZS gives it natural flexibility. It adapts to irregular shapes without leaving deep scratches, unlike conventional grinding wheels.

Applications and materials compatible with the CG-ZS wheel

The Scotch-Brite™ CG-ZS wheel is designed for stripping, deburring, and cleaning metal surfaces without altering their geometry or leaving deep marks.

It is used on raw or machined parts, where it is necessary to eliminate rust, mill scale, oxidation, or welding residues while preserving the integrity of the metal.

Compatible materials:

• Steel and stainless steel
• Aluminum and light alloys
• Cast iron
• Titanium and non-ferrous metals

Typical applications:

• Deburring of mechanical parts after machining
• Stripping of welds and weld beads
• Removal of rust and oxidation
• Cleaning of surfaces before surface treatment or painting
• Finishing and light satin finishing

The non-woven structure of the CG-ZS wheel allows it to adapt to the contours of parts. It works gently, with no risk of material gouging or excessive heating.

It is suitable for work in boilermaking workshops as well as for industrial maintenance operations or surface preparation in locksmithing.

Comparison: Scotch-Brite™ CG-ZS wheel vs. other stripping discs on the market

The Scotch-Brite™ CG-ZS wheel is not an abrasive like others. Here is how it positions itself against common industrial stripping solutions.

Conventional abrasive discs (corundum or zirconia grain) remove material quickly, but they scratch, heat, and risk deforming thin parts. The CG-ZS, however, works gently on the surface without attacking the metal in depth.

Compared to a rotary wire brush, the non-woven wheel generates far fewer sparks and does not leave ferric particles embedded in stainless steel, a decisive advantage in food or pharmaceutical environments.

Product	Type	Material removal	Risk of overheating	Typical usage
Scotch-Brite™ CG-ZS (3M)	Non-woven wheel	Low to moderate	Very low	Stripping, cleaning, stainless finish
Scotch-Brite™ EXL (3M)	Non-woven wheel	Low	Very low	Finishing and gentle polishing
Zirconia fiber disc (e.g., 3M 787C)	Rigid abrasive disc	High	Moderate to high	Grinding, steel deburring
Rotary wire brush	Steel / stainless brush	Moderate	Moderate	Descaling, rust stripping
Corundum flap disc	Flexible abrasive disc	Moderate to high	Moderate	Sanding, general-purpose deburring

The CG-ZS stands out for its ability to strip without creating localized heat zones. It is the ideal tool when the part must remain dimensionally stable after treatment.

For finishing operations on stainless steel, aluminum, or treated steel, it clearly outperforms rigid discs. It effectively complements an abrasive range without replacing them: it is used where precision takes precedence over removal speed.

Usage tips and safety for the CG-ZS non-woven wheel

The 3M™ Scotch-Brite™ CG-ZS non-woven wheel gives its best results when used under the right conditions. Some simple rules to follow to work efficiently and safely.

Machine settings and precautions for use

The CG-ZS is designed to be mounted on an angle grinder or stationary machine. Always check that your machine's speed does not exceed the maximum allowable speed indicated on the wheel.

It is imperative to use a mandrel adapted to the wheel's bore diameter. Improper mounting causes vibrations, premature wear, and a risk of breakage.

Apply light and even pressure to the part. The non-woven wheel works through progressive abrasion: forcing it does not accelerate the result; it simply reduces the abrasive's service life.

For stripping stainless steel, avoid any prior contact of the wheel with ordinary steel. Cross-contamination can cause corrosion on stainless steel.

Systematically wear the appropriate personal protective equipment:

• Safety glasses or face shield against debris
• Cut-resistant gloves
• Hearing protection if used for prolonged periods
• Dust mask when working on treated metals

Store the wheel away from humidity and impacts. A non-woven abrasive damaged before use can become unbalanced during rotation.

FAQ - 3M™ Scotch-Brite™ CG-ZS non-woven wheel

1. What exactly is the 3M™ Scotch-Brite™ CG-ZS non-woven wheel used for?

The CG-ZS is designed for stripping, deburring, and cleaning metal surfaces without damaging them. It removes rust, oxides, welding residues, and old layers of paint.

2. On which materials can this wheel be used?

It is suitable for steel, stainless steel, aluminum, and most non-ferrous metals. Its non-woven abrasive works gently: it does not tear away base metal, unlike a conventional grinding wheel.

3. What is the difference between the CG-ZS and a standard Scotch-Brite™ wheel?

The CG-ZS incorporates a zirconium grain, which is more aggressive and resistant than standard alumina. It lasts longer and cuts better on hard materials. An alumina grain Scotch-Brite™ wheel would be preferred for light finishing or soft metals.

4. Can it be used on a standard angle grinder?

Yes. The CG-ZS wheel is compatible with standard threaded spindle angle grinders. Simply verify that your machine's maximum speed does not exceed the limit indicated on the wheel before use.

5. Does the wheel leave marks on stainless steel?

No, that is one of its great advantages. The Scotch-Brite™ non-woven material does not contaminate stainless steel and does not leave burn marks. The surface remains clean, ready for finishing or surface treatment.

6. What lifespan can be expected from this wheel?

Lifespan depends on the pressure applied and the material being worked. Thanks to the self-sharpening zirconium grain, the CG-ZS maintains its performance longer than an equivalent alumina grain wheel. Proper use, without excessive pressure, significantly extends its service life.
