A brush is a tool with bristles, wire or other filaments, used for cleaning, grooming hair, make up, painting, surface finishing and for many other purposes. It generally consists of a handle or block to which the filaments are affixed either parallel or perpendicular, depending on the way the brush is to be gripped during use. The material of both the block and bristles or filaments is also chosen to withstand hazards of its application, such as corrosive chemicals, heat or abrasion.

A common way of setting the bristles, brush filaments, in the brush is the staple or anchor set brush in which the filament is forced with a staple by the middle into a hole with a special driver and held there by the pressure against all of the walls of the hole and the portions of the staple nailed to the bottom of the hole. The staple can be replaced with a kind of anchor, which is a piece of rectangular profile wire that is anchored to the wall of the hole, like in most toothbrushes. Another way to attach the bristles to the surface can be found in the fused brush, in which instead of being inserted into a hole, a plastic fiber is welded to another plastic surface, giving the option to use different diameters of bristles in the same brush.

Configurations include twisted-in wire (e.g. bottle brushes), cylinders and disks (with bristles spread in one face or radially).


 

Brushes used for cleaning come in various sizes. They vary in size from a that of a toothbrush, to the standard household version accompanied by a dustpan, to *6" deck brushes. There are brushes for cleaning tiny cracks and crevices and brushes for cleaning enormous warehouse floors. Brushes perform a multitude of cleaning tasks. For example, brushes lightly dust the tiniest figurine, they help scrub stains out of clothing and shoes, they remove grime from tires, and they remove the dirt and debris found on floors with the help of a dust pan. Many kinds of specialty brushes are used for cleaning vegetables, cleaning the toilet, washing glass, finishing tiles, and sanding doors.

Paintbrushes are used for applying ink or paint. Paintbrushes are primary used by artists for painted pictures. A special kind of drawing is the so called paintbrush-drawing, drawings only done with paintbrushes instead of pencil or pen.


 

The styles of brush tip seen most commonly are:

• Round: pointed tip, long closely arranged bristles for detail
• Flat: for spreading paint quickly and evenly over a surface. They will have longer hairs than their Bright counterpart.
• Bright: shorter than flats. Flat brushes with short stiff bristles, good for driving paint into the weave of a canvas in thinner paint applications, as well as thicker painting styles like impasto work.
• Filbert: flat brushes with domed ends. They allow good coverage and the ability to perform some detail work.
• Fan: for blending broad areas of paint.
• Angle: like the filbert, these are versatile and can be applied in both general painting application as well as some detail work.
• Mop: a larger format brush with a rounded edge for broad soft paint application as well as for getting thinner glazes over existing drying layers of paint without damaging lower layers.
• Rigger: round brushes with longish hairs, traditionally used for painting the rigging in pictures of ships. They are useful for fine lines and are versatile for both oils and watercolors.
• Stippler and deer-foot stippler: short, stubby rounds
• Liner: elongated rounds
• Dagger
• Scripts: highly elongated rounds
