Twisted in wire brushes are known by many names, such as spiral, tube, bottle, pipe and more, but generally they are manufactured using the same construction technique.
A piece of wire is doubled over and bristle material is inserted between the fold of the wire stem, the wire stem is then twisted into a brush.
The most common brush “fills” are steel wire, stainless steel wire, brass wire, and nylon.
All Bordo condensor tube and boiler tube brushes feature a BSW male threaded ferrule.
They may be used by hand or with power equipment.
All brushes are available as single or double spiral.
The double spiral are a heavier construction with a more dense brush face for more aggressive brushing and are ideally suited to use with a power tool.
End brushes are used for industrial applications where space is an issue.
These brushes are typically used with a high speed hand-held tool, such as a die grinder, for applications including cleaning, polishing, deburring and surface preparation.
Bordo hex shank crimp wire end brushes are designed for use with low speed electric drills for removing scale, rust, and paint and other surface preparation including deburring and polishing.
Crimp wire brushes are not as aggressive as their twist knot equivalents.
These brushes are constructed using hi-tensile wire to ensure superior performance and a long life.
