A hand sander is a hand-held tool used to sand down rough materials and uneven surfaces.
The aim of the tool is to speed up the sanding process when working on large areas. It also prevents possible injury to the user’s hands and fingers, in addition to reducing the fatigue of manual sanding, compared with using sandpaper alone.
A hand sander is designed with an ergonomically structured handle. Sanding can cause aching to the hands and wrists after a while, and so the rounded handle is designed to prevent this sort of discomfort during long jobs.
Using a hand sander is also much quicker than just using sandpaper. This is due to the fact that the large, flat surface of the hand sander applies even pressure over the area being worked upon, allowing the user to cover a greater area in less time.
