• 1. What is a Random Orbital Sander?

  The random orbit sander belongs to the group of orbital sanders and is particularly suitable for fine sanding. The round The grinding disc is eccentrically mounted and can therefore oscillate in a circle. Via an additional dust extraction system grind in a healthy and environmentally friendly way.

• 2. How is the random orbital sander used correctly?

  In contrast to other grinding machines, the random orbital sander is only switched on when it is on the workpiece. In addition, you should always keep it parallel to the work surface, since otherwise notches can quickly appear in the wood. In addition, make sure that the dust extraction of the random orbital sander is always switched on.

  Our tip:

  Instead of increasing the pressure when working with an eccentric sander (if the sandpaper is blunt), it should be changed beforehand. Due to the increased pressure on the grinding disc this slows down and the material removal decreases.

• 3. Which grain size do I use for the random orbit sander?

  In general, there are two models of abrasive paper: The eccentric sander 125 and the eccentric sander 150. The number stands for the size of the grinding disc in millimetres. Which grain You use depends on what you're doing with the orbital sander. The higher the number of grains, the finer they are and the less material is removed. We recommend using a a slightly coarser grain before fine grinding.

• 4. How high should the performance of the random orbit sander be?

  In principle, the higher the number of watts, the higher the performance of the random orbital sander. The higher the power of the random orbit sander, the faster the grinding wheel moves. The more the grinding wheel moves, the higher the removal rate of the machine. There is a suitable random orbit sander for every application. Our devices of the brands Makita, Bosch, Triton and Mafell have a power consumption between 280 and 750 watts. Here you will find random orbital sanders from Festool.
