The TC-OS 18/187 Li-Solo cordless orbital sander from Einhell is a lightweight, handy orbital sander with active dust extraction that fits perfectly in the hand thanks to its ergonomic soft-grip handle. It can be used flexibly, especially for sanding larger, flat surfaces such as formwork or cladding. The sanding paper can be easily attached with micro Velcro or clamped with a clamping device. The scope of delivery includes a dust collection bag and a suction adapter, but without a battery and without a charger. The separately available 18-volt system battery from the Power X-Change series, which is also used in Einhell tools and garden tools, is required to operate the TC-OS 18/187 Li-Solo cordless orbital sander.

Specifications

Same summary

The Einhell TC-OS 18/187 Li-Solo cordless orbital sander enables efficient sanding of wood and other flat surfaces where there is no access to a power outlet or where cables get in the way. Due to the larger diameter of the sanding disc, it is suitable for fast processing of wider surfaces, but slightly less so for very precise work or sanding in narrow corners. This model does not come with a battery or charger, so it is the most sensible choice for users who already have compatible Einhell battery systems. Users who need a multi-purpose tool for different materials or more demanding specialized tasks should make sure that the type of sander is also suitable for their needs before purchasing.

User view

Typical users of this cordless sander are home craftsmen and hobbyists who often renovate furniture, parquet floors or carry out small finishing works on wood - especially where there is no direct access to electricity or where the cable hinders movement. The tool is also practical for projects on terraces, gardens or in the garage, when we want more freedom of movement and a quick transition between tasks.

More users are choosing Einhell tools because of their broad battery platform, which allows one battery to be used for several different devices, providing greater flexibility when working at home or in the field.

Answers to frequently asked questions

Can I also use this sander to sand painted surfaces or varnished wood?

Yes, an orbital sander is suitable for sanding painted, varnished or raw wooden surfaces. It is recommended to choose the appropriate grit of sandpaper depending on the desired level of material removal.

Which battery fits this model?

The TC-OS 18/187 Li-Solo is compatible with all 18V batteries from the Einhell Power X-Change series. If you already have a tool from this series, you can use your existing batteries.

Is the sander light enough for working overhead or at height?

Without a battery, the sander is light enough to work comfortably for long periods of time, even when sanding overhead or on wall surfaces. However, we recommend taking breaks during longer jobs.

Is the tool also suitable for sanding close to edges or in tight corners?

Orbital sanders with larger disc diameters are more effective on flat and wider surfaces. For very precise work on edges or corners, a smaller or specialized sander is more suitable.

What supplements do you recommend for optimal results?

In addition to high-quality sandpaper of the appropriate grit, we recommend using dust extraction accessories if you are sanding indoors. This ensures a cleaner working environment and better visibility of the surface.
