| Orbit Sander |
Finishing sanders come in two main types: block sanders and random orbit. Although either tools can be used as a finishing sander, they excel at different applications. Random orbit sanders are better for sanding large areas quickly. However, finishing/block sanders provide a better finish while also have the obvious advantage of being able to get closer into the corner as they do not have a circular base like orbital sanders.
Further, block sanders can use standard sandpaper that you cut down to shape, while random orbit sanders need specific circular sheets and this can make the running cost higher. If you only have the money for one of these sanders, we recommend a block/finishing sander.
