XIIW 3800W Concrete Grinder with 4 Grinding Heads – energy-saving, precise, and versatile

Uneven concrete surfaces, stubborn adhesive residues, or old coatings are often difficult to remove with conventional tools. The XIIW 3800W Concrete Grinder was developed for the efficient processing of larger floor areas and is ideal for renovation, restoration, workshops, and construction sites.

The 4-head grinding system ensures even material removal and stable guidance. Thanks to the long handle and balanced weight distribution, the machine can be guided across the surface in a controlled way without requiring sustained high pressure.

Key benefits

• Powerful 3800W motor: High removal performance on concrete, screed, mortar residue, tile adhesive, and old coatings.
• 4-head grinding system: Four simultaneously working grinding heads enable even processing of larger surfaces.
• 6 adjustable speed settings: The speed can be adjusted to match the material and the accessories used.
• Up to 6000 rpm: Suitable for rough material removal, surface cleaning, and preparatory sanding work.
• Dust-reduced operation: Connection option for a suitable industrial vacuum cleaner.
• Additional water supply: The included submersible pump can be used to reduce dust in accordance with the operating instructions.
• Grinding close to edges: The foldable protective cover makes it easier to work along walls and edges.
• Long guide handle: Enables a more comfortable posture when working on floor surfaces.
• Extensive accessories: Various grinding, polishing, and cleaning attachments are already included in the scope of delivery.

Efficient processing of concrete and floor surfaces

The four grinding heads distribute pressure evenly across the surface. This makes the machine particularly suitable for sanding down uneven areas, removing old residues, and preparing floors for new coatings, tiles, or floor coverings.

The machine's own weight supports the grinding process and reduces the amount of manual pressure required. The long handle improves control and makes it easier to guide across larger areas.

6 speed settings for different tasks

Depending on the surface and the accessories used, the speed can be set in six stages. Lower speeds are suitable, for example, for controlled polishing and cleaning work, while higher speeds allow greater material removal.

Before starting work, the speed should first be tested on a small, inconspicuous area.

Dust extraction and water supply

Fine dust is produced when grinding concrete and screed. The XIIW concrete grinder therefore has a connection option for a suitable industrial vacuum cleaner. This reduces dust generation and improves visibility of the work area.

In addition, a submersible pump and a water hose are included in the scope of delivery. The water supply may only be used in accordance with the operating instructions. Electrical components, switches, plugs, and the motor must not come into contact with water.

Suitable applications

• Grinding down uneven concrete surfaces
• Processing screed and cement-based substrates
• Removing tile adhesive and mortar residue
• Removing old paint and floor coatings
• Preparing floors for new coatings
• Cleaning and processing natural stone surfaces
• Renovation work in garages, basements, and workshops
• Restoration work indoors and outdoors

With the appropriate accessories, the device can also be used for selected polishing, cleaning, and surface tasks. The accessories used must always be suitable for the respective material and the set speed.

Frequently asked questions

Can the concrete grinder be connected to a vacuum cleaner?

Yes. The machine has a connection option for a suitable industrial vacuum cleaner. For fine concrete dust, a vacuum cleaner approved for this purpose with a suitable filter system should be used.

Is the machine suitable for wall surfaces?

The concrete grinder is mainly designed for horizontal floor surfaces. Due to its weight of about 8.6 kg, it is only suitable to a limited extent for longer work on vertical surfaces.

Can the machine be used to remove tile adhesive?

Yes. With the right diamond grinding cups, the device is suitable for removing many cement-based adhesive, mortar, and coating residues. The result depends on the hardness and thickness of the material.

Which grinding discs are compatible?

Use only grinding attachments with the correct diameter, a suitable M10 mount, and sufficient speed rating. Before buying additional grinding discs, the exact mount should be checked.

Can the machine be used with water?

The included submersible pump allows controlled water supply in accordance with the operating instructions. Water must never come into contact with the motor, switch, cable, plug, or other electrical components. For additional safety, the use of a suitable residual current device is recommended.

For renovation, restoration, and demanding floor work

The XIIW 3800W Concrete Grinder combines four grinding heads, adjustable speed, and a long guide handle in a powerful floor processing machine. It is suitable for DIY users, renovation companies, and professional users who want to grind concrete surfaces efficiently, clean them, or prepare them for the next work step.

Note: Always use suitable protective clothing, safety goggles, hearing protection, and respiratory protection. Before each use, check whether the grinding attachments are correctly mounted, undamaged, and approved for the set speed.
