Powerful 20V sander for rough & hard sanding jobs on larger surfaces

Powerful 20V eccentric sander. Thanks to the high speed and number of movements per minute, the machine quickly removes any old layer! This eccentric machines from VONROC, unlike other types of sanders, makes both a circular as well as an orbital sanding movement. These movements allow you to quickly remove old paint or varnish layers from large surfaces. Perhaps the biggest advantage of this random orbital sander is that thanks to its double action, you are less likely to see circular marks on the sanded surfaces.

Where do you use this sander with eccentric movements?

Thanks to the high speed up to a maximum of 10,000 rotations per minute, this sander quickly removes a lot of material! The speed is variable adjustable, so you can easily choose the right sanding speed for the material which you are sanding.

This makes it ideal for the following jobs:

  • Rough sanding jobs: for example, sanding bare surfaces such as doors and door frames
  • Rounded & curved surfaces: the rotating disc also allows you to sand rounded surfaces, such as the bottom of a boat.
  • Different materials: this orbital sander is not only suitable for sanding wood, but also for metal and plastic.
  • Other surfaces: for example, sanding furniture with curved edges or removing scratches from synthetic window frames.

VONROC Power 20V Platform - Which type of battery do you need for your sander?

This cordless sanding machine is supplied without a battery and charger. This is because the sander is part of the VONROC VPower 20V Platform. You can optionally order the interchangeable 2.0Ah or 4.0Ah battery. If you want to combine the sander with another machine from the VONROC VPower 20V Platform, one battery and a quick charger is enough! Choose only what you need and that, for a competitive price!
