Twisted Brushes Design Specifications

Brush Diameter

The diameter of the twisted brush will vary within the different constructions and range from .020” up to 8”. Brushes can be stiffened by either shortening the trim length or using a larger diameter bristle, or the brushes can be softened for an extended life by using a smaller bristle diameter. This diameter determines the classification of the brush.

Brush Part Length

The brush part is the working function of any twisted brush. Generally the brush part is only on one end of the brush, but you can elect to have the brush part centered with stem wire on either side. Another choice, depending on the stem construction, is having a brush part on both ends. Your made-to-order brush can have a brush part varying from 1/2” or larger.

Stem Materials and Construction

There are other twisted brush characteristics that need to be determined to find the most effective brush for your application needs including stem material, stem gauge/diameter and overall length of the brush. The most common stem wire materials used are galvanized steel and stainless steel, although brass stem wire is also available.

The stem gauge is the diameter of the stem wire construction when twisted together. The stem wire after the brush part is often referred to as the handle length. Overall length is measured from the tip of the brush part length to the end of the brush and can range from 3/4” or larger. We offer various accessories to extend the overall length including a plastic tube, steel tube, hex-shank, threaded coupling or wood or plastic handle, which can be attached to the stem wire.

Brush Tip Styles

Twisted brushes can be machined with many different brush tip styles, depending upon the stem construction and fill material selected. For example, a twisted brush with wire filament is not best suited for a turned tuft brush tip.

Below are the most common brush tip styles:

•  Continuous end
•  Broken end
•  Turned tuft
•  Vinyl tip
•  Tied tuft
