| Sandblaster
|
|
Machine which wears away a coating, by use of sand, grit or other substance in a high-pressure air stream as it hits the surface. The air pressure and the size and shape or opening of the nozzle help to vary the force or coverage of the stream. Different abrasive materials, in different sizes, can be used depending on the reason for the use, such as whether it is a delicate or sturdy surface. |

| Sander, orbital
|
|
Vibrating sander that moves in a circular motion along the surface, which removes sanding marks with a finer sandpaper to create a smooth surface. |
| Sander, straight line
|
|
