Wire brushes are an effective tool that is used in a variety of applications where the goal is to remove undesirable material from the surface of a material. This can be in the form of rust on a metal prior to being coated, or even removing an old coating before a more robust, and newer coating is applied.
When used in a welding environment, wire brushes are often used to remove the oxide layers on metals such as aluminium or stainless steel, as these oxide layers can create defects in the weld, reducing the strength.
Post welding, wire brushes can be an effective tool when it comes to removing slag and spatter, while they are also an efficient method used to remove burrs.
If you are looking for wire brushes, but aren’t sure which type is best suited to your needs, read the information below, or contact us to discuss your needs.
How to use a wire brush
Wire brushes are typically used in conjunction with a machine or operated manually. At Engweld, we supply a wide range of wire brushes for drills and angle grinders, rather than handheld versions, which will come with a handle.
Instead, our wire brushes for drills are simply placed onto the drill or angle grinder and are electrically powered. One advantage of using them instead of grinding discs or flap discs is that they contour to the shape of the material that is being worked with, this allows the user to effectively remove material from irregular surfaces.
How to select the right wire brush
There are three main wire materials available. Brass, carbon steel and stainless steel, and that type that is required will be largely dependent on the material that is being worked with.
Of the three, brass is the most versatile and can be used on virtually any project, no matter what type of metal is involved, while stainless steel and carbon steel are better suited to specific material types.
Take a look at our handy guide which indicates the type of wire brush that can be used with what materials.
Brass - Aluminium, Brass, Copper, Iron, Plastic, Carbon Steel, Stainless Steel, Wood
Carbon Steel - Iron, Carbon Steel, Wood
Stainless Steel - Aluminium, Brass, Copper, Stainless Steel, Wood
And as with any other abrasives, you need to consider the coarseness of your wire brush. Fine to very fine wire is well suited for light-duty applications, whereas for more demanding, heavier duty applications medium to coarse wire is recommended.
We supply three main types of wire brushes, cup brushes, wheel brushes, and end brushes.
Cup Wire Brushes - Typically used for descaling, polishing and surface preparation. They have a cup-shaped base, along with a high density of wire filaments, which can either be crimped, knotted or twisted.
Wheel Wire Brushes - Mainly used with angle grinders or mounted onto an arbour, they are used for removing paint, deburring, polishing, cleaning and finishing. The wires can either be crimped or knotted, at a length of between 6 to 8 inches, and they can even be gang mounted to cover a larger area.
End Wire Brushes - Ideal for use in applications where space is limited or access is restricted, they have a similar appearance to that of cup brushes. They are a great option for preparing the surface of a meal for welding, as well as spot facing, flash removal, polishing moulds, deburring holes and cleaning castings.
There are also several typical styles of filament available, and again, each is best suited to a different type of application.
Straight or Level - Generally used for lighter applications, straight filaments are less dense and therefore are less abrasive.
Round Crimped - Offering a great brush action, round crimped filaments will usually have a wave appearance, with the nature of the crimp being determined by the crimps per inch, frequency and the crimp depth.
Twisted - Twisted filaments take straight or crimped filaments, and twist several of them together in a batch. This increases the diameter of the filaments, meaning the user is able to work on a larger area.
Rectangular - Great for heavy-duty, high-performance applications, they apply greater levels of abrasion due to the solid line of contact with the surface being worked with.
At Engweld, we supply wire brushes from two industry-leading brands. KLINGSPOR and Abracs.
KLINGSPOR wire brushes can be used for a wide range of applications in steel and stainless steel sectors. A significant advantage of wire brushes compared to coated abrasives is that the brushes only work on the workpiece surface without changing its shape.
KLINGSPOR wire brushes are high-quality tools for the following applications:
The KLINGSPOR wire brushes offer a comprehensive product program for a wide range of processing tasks, materials and machines.
