The scratch brush is often used to remove the dead luster on, or to impart a smooth surface to an object. They are usually made of brass or steel wire and of a variety of shapes to suit the object. Some of the forms are shown in the figure.
The wheel brushes are used on the lathe, the objects being manipulated in contact with the rapidly revolving brush. The brush is usually kept moistened by a small stream of water while in use.
