What Are Tube Brushes?

Tube brushes are used for cleaning inside of holes and other hard-to-reach areas such as tubes, internal bores, and cylindrical cavities. Applications include the removal of chips, dirt, oil, rust, and corrosion. Tube brushes, which are also known as cylinder brushes, feature a twisted-in-wire construction and are specified by hole-diameter and fill material.

All of the tube brushes in BRM’s six-piece kits are Made in the USA and part of the Los Angeles, California company’s Series 84 family of products. These high-quality industrial brushes are ideal for cleaning and deburring through-holes produced by drilling and machining. Unless burrs, contaminants, and other surface imperfections are removed, part misalignments may occur.

Three Tube Brush Kits, Six Brushes in Each

Each of BRM’s three tube brush kits contains six brushing tools for a range of hole-sizes.

• Kit A contains tube brushes for holes 1/8”, 3/16”, 1/4”, 5/16”, 3/8”, and 7/16”.
• Kit B contains tube brushes for holes 1/2", 9/16”, 5/8”, 3/4”, 7/8”, and 1”.
• Kit C contains tube brushes for holes 1-1/8”, 1-1/4”, 1-3/8”, 1-1/2”, 1-5/8”, and 1-3/4”.

When ordering tube brush kits, remember to specify the appropriate part number for the fill material: stainless steel, carbon steel, brass, nylon, or natural bristle. Also, note that while the ringed handles on Series 84 tube brushes support their manual use, these rings can be cut-off to support tube-brush use under power with portable tools or machinery.
