Your benefits at a glance

Optimized 3-disc system – grind more controlled & evenly

The newly developed 3-disc design with counter-rotating grinding heads supports a more even distribution of force during grinding. This reduces lateral pulling and strong vibrations, allowing the machine to be guided more smoothly and with greater control, especially on larger surfaces. The result is a more even grinding pattern with more comfortable handling.

Powerful 3800W motor with 6 speed settings

The powerful 3800W motor is designed for demanding grinding and renovation work. With the 6-stage speed control, the grinding performance can be adjusted flexibly to the material, surface, and task at hand. At a speed of up to 3000 rpm, the machine is suitable for removing, smoothing, and preparing a wide variety of surfaces.

Ergonomic work while standing

Instead of having to work large floor areas for long periods in a bent-over or crouched position, the approx. 2 m long guide handle enables a more comfortable working posture. The sturdy 3-wheel guidance supports controlled movements in different directions and makes it easier to guide the machine over larger surfaces. Ideal for longer renovation and refurbishment work.

Dry or wet grinding – suited to the working environment

Depending on the application, the XIIW concrete grinder can be used for dry or wet grinding tasks. When dry grinding, the resulting dust can be captured directly via the existing extraction port.

For water-resistant work areas, a water connection is also available. When wet grinding, the water supply helps bind dust and cool the grinding discs. The included submersible pump and water hose make water supply easier during work.

Note: Dry and wet grinding are used separately depending on the material and working environment.

Edge grinding near walls and corners

The removable edge cover makes it easier to work in close proximity to walls, edges, and hard-to-reach areas. This allows floor surfaces to be worked as far as possible right up to the edge without having to switch the entire machine.

Additional handle for flexible applications

In addition to the long guide handle, the machine features a straight auxiliary handle. This provides extra control in different working positions and also makes selected grinding tasks on vertical surfaces easier.
