Accordingly, how does an orbital sander work?

Orbital sanders work by elliptically rotating a sanding disk. No matter the wood grain's direction, an orbital sander will smooth the surface without leaving marks. Because of this, you can easily sand two pieces of wood at the same time, even if their grains are in different directions.

One may also ask, what should I look for in an orbital sander? If you want to choose the best one for your project, here's what you should look for.

1. Variable speed. When shopping for a random orbital sander, it is recommended that you get one with variable speed.
2. Vibration control.
3. Dust Collection.
4. Weight.
5. Changing sanding grit paper.
6. Good grip.
7. Long cord.

In respect to this, what is the difference between an orbital sander and a sheet sander?

Sheet sanders are designed to work with partial sheets of standard sandpaper, whereas random orbital sanders require round disks, typically attached to the sander base with either adhesive or hook-and-loop type fasteners. Sheet sander pads (and the sandpaper on them) are square, so the tool can get into corners.

Why do orbital sanders have holes?

Anyway, the reason you want those holes is to allow the sander to suck away the sawdust and throw it in the dust collection bag or chamber. If it doesn't do that, the dust gets trapped under the sander disk and keeps it from sanding efficiently. The hole patterns are more or less standardized, .
