The Advantages of the Rotating Sander
In Comparison to its brothers, the Belt Sander and the Angle Grinder, the Rotating Sander has a lot of advantages.
When buying sanding discs, you can't go far wrong in terms of dimensions and hole spacing, as these hardly differ even between sanding discs from different manufacturers. Depending on the task at hand, you can choose freely here. It does not hurt to compare the sanding disc and the rotating sander before buying. However, the quality of the sanding discs plays a major role, and you should pay attention to this when buying!
Compared to a belt sander, the material removal rate is lower with an rotating sander and a hard edge is less likely to form on the edge of the sandpaper due to the eccentric movements. This means that sanding does not have to be done quite as carefully to avoid unevenness in the material. However, the removal rate is higher than with the classic orbital sander, which noticeably reduces the working time.
