3M™ Cubitron™ 3 2-in-1 Wheel: cutting and grinding in a single abrasive

The 3M™ Cubitron™ 3 2-in-1 Wheel does the work of two wheels in a single pass: cutting and grinding without changing abrasives.

Its Precision-Shaped Grain technology ensures a clean cut and extended life, even on the most demanding steels.

Fewer stops, fewer wheels consumed, more productivity on the job site.

What is the 3M™ Cubitron™ 3 2-in-1 Wheel?

The 3M™ Cubitron™ 3 2-in-1 Wheel is an abrasive wheel designed to perform both cutting and grinding with one single tool. No more switching wheels mid-task.

It adapts to standard angle grinders and is aimed at professionals who work with steel, stainless steel, and ferrous metals daily.

Precision-Shaped Grain Technology: 3M's triangular abrasive grain

Cubitron™ 3 incorporates 3M's Precision-Shaped Grain (PSG) technology. The grains are made of sol-gel ceramic and cut into precise triangular pyramid shapes.

These micro-tips slice through material rather than rubbing it. The result: less heat, less grain crushing, and faster cutting than conventional random-grain abrasives.

The grain continuously self-sharpens during use: as one tip wears down, a new sharp edge appears. Performance remains consistent from the first pass to the last.

Here is what specifically sets Cubitron™ 3 apart from its predecessors and conventional abrasives:

• Extended life compared to Cubitron™ II
• Less pressure required on the tool
• Low heat generation on the workpiece
• Compatible with steel, stainless steel, and ferrous metals
• Dual function: cutting and grinding without changing the wheel

Product	Grain Technology	Primary Usage	Versatility	Target Materials
3M™ Cubitron™ 3 2-in-1	Triangular ceramic PSG	Cutting + grinding	✔ Dual function	Steel, stainless steel, ferrous metals
3M™ Cubitron™ II (cutting wheel)	Triangular ceramic PSG	Cutting only	✘ Single function	Steel, stainless steel
Norton Quantum (grinding wheel)	Random ceramic	Grinding only	✘ Single function	Steel, stainless steel
Conventional alumina abrasive	Brown/white fused alumina	General grinding	✘ Single function	Common steel

Two functions, one wheel: combined cutting and grinding

The 3M™ Cubitron™ 3 2-in-1 wheel does what most abrasives cannot: cut and grind with one single wheel.

No more changing wheels mid-operation. You cut, you deburr, you grind, without interrupting your work.

This dual usage is made possible by the precision geometry of the Cubitron™ 3 grains, which cut clean at 90° and work at an angle for grinding, depending on the chosen angle of attack.

In practice, this makes a big difference:

• Fewer wheels to store and transport on the job site
• Real time savings on mixed cutting and deburring operations
• Reduced risks associated with frequent accessory changes
• Only one reference to order, manage, and restock

The wheel remains effective on steel, stainless steel, and ferrous metals, whether for heavy-duty cutting or light finishing passes.

At Dagobert Industrie, this is exactly the type of product we recommend for workshops and construction sites looking to reduce downtime without sacrificing cutting quality.

Performance and technical characteristics of the Cubitron™ 3 2-in-1

The 3M™ Cubitron™ 3 2-in-1 wheel is based on precision-shaped triangular abrasive grain technology. These grains self-sharpen during use: they break cleanly rather than dulling, maintaining a high material removal rate throughout the life of the wheel.

Concrete result: fewer passes, fewer wheels consumed, and less downtime for changing abrasives.

Its dual-use design allows you to cut and grind with one single wheel, simply by changing the angle of attack. Flat, it cuts. Angled, it grinds. No tool manipulation, no wheel changes between the two operations.

Dimensional specifications and maximum speed

The Cubitron™ 3 2-in-1 is available in several standard diameters, compatible with market-standard angle grinders. The wheel thickness is optimized to combine rigidity for grinding with precision for cutting.

Comparison: Cubitron™ 3 2-in-1 wheel vs. competing abrasive wheels

The abrasive wheel market offers many references. Here is how the 3M™ Cubitron™ 3 2-in-1 Wheel positions itself compared to widely used solutions.

Comparison table of the market's main cutting/grinding wheels

Product	Manufacturer	Function	Abrasive Technology	Compatible Materials	Estimated Life
Cubitron™ 3 2-in-1	3M	Cutting + grinding	Precision-shaped triangular grain (ceramic)	Steel, stainless steel, ferrous metals	Very high
Cubitron™ II (cutting wheel)	3M	Cutting only	Precision-shaped triangular grain (ceramic)	Steel, stainless steel	High
Cubitron™ II grinding wheel	3M	Grinding only	Precision-shaped triangular grain (ceramic)	Steel, stainless steel	High
Flexovit Specialist cutting wheel	Flexovit	Cutting only	Alumina corundum	Steel, ferrous metals	Average

Pferd Inox 2-in-1 wheel	Pferd	Cutting + grinding	Alumina corundum special for stainless	Stainless steel, steel	Average

Most competing wheels are single-use: cutting or grinding, but not both. Changing wheels takes time and costs productivity.

The Cubitron™ 3 2-in-1 eliminates this compromise. A single wheel is enough to cut and grind on the same job site.

Its precision-shaped triangular grain technology (3rd generation) outperforms classic ceramic grains in cutting speed and longevity. Standard alumina corundum-based wheels wear out significantly faster under the same conditions.

Key advantages of Cubitron™ 3:

• Real versatility: cutting and grinding without changing wheels
• 3rd generation ceramic grain: cuts faster, lasts longer
• Low heat generation: protects the part and the operator
• Compatible with steel and stainless steel: no metal contamination

FAQ - 3M™ Cubitron™ 3 2-in-1 Wheel

1. What is the difference between cutting mode and grinding mode on this wheel?

In cutting mode, you use the edge of the wheel to cut steel or stainless steel.

In grinding mode, you tilt the tool and work with the face of the wheel to deburr or surface.

The Cubitron™ 3 2-in-1 is designed to handle both uses without premature degradation.

2. On which materials can it be used?

It is optimized for steel, stainless steel, and ferrous metals in general.

Its 3M Precision-Shaped Grain (PSG) slices cleanly without crushing the material, which limits heat buildup on stainless steel.

3. Can you really replace two wheels with one?

Yes, that is the central selling point of this product. A single wheel replaces a traditional cutting wheel and a grinding wheel.

In practice, this reduces wheel changes on the job site and limits the stock of abrasives to manage.

4. What is its lifespan compared to a standard wheel?

The Cubitron™ 3 technology incorporates third-generation PSG grains that self-sharpen during use.

The service life is significantly longer than that of a classic aluminum oxide abrasive wheel.

In intensive conditions, one typically observes a longevity 2 to 3 times higher than a conventional wheel of the same diameter.

5. Is this wheel compatible with all angle grinders?

It is compatible with standard angle grinders equipped with a 22.23 mm arbor (universal bore).

Check that your machine's maximum speed is less than or equal to the maximum peripheral speed indicated on the wheel before use.

6. Are there specific safety precautions?

Yes. In cutting mode, the wheel must never be used with excessive lateral pressure: it is not designed for aggressive face-grinding.

Always wear a face shield, gloves, and hearing protection. Respect the protective guard mounted on the grinder.

At Dagobert Industrie, we recommend always checking the visual integrity of the wheel before every use.
