One of the best ways to remove rust is by using a wire wheel. It uses a stiff wired section to clean the areas corroded by rust, getting most of the rust off before sanding is done to polish the areas further.
The best wire wheel for rust removal offers users the ability to clean, blend in edges, finish surface, and polish in addition to rust removal. The wire wheel is more of a power brush than a typical wheel, and it is motor-driven.
This article will give you the top five wire wheels to use for rust removal and explains what to consider when shopping for a wire wheel. Keep on reading!
How Does the Wire Wheel Work?
A wire wheel works by using burrs to reach all the hidden places where rust hides and weakens the metal. It is used in much the same way you would use a grinding tool but only for cleaning. The wire wheels come with two basic types of wire brushes: Crimped wire brushes and knotted wire brushes. It features a keyway to enable use with a grinding tool.
Knotted wire brushes are used for the more aggressive rust removal. They typically feature stainless and carbon steel, which is better at supporting aggressive cutting and brushing. The brush has a twisted tuft for two-thirds of the wire filament, and the remaining third of the filament is flared. Some models come with the entire wire filament completely twisted.
The knotted wire brushes are used on very stubborn rust.
Crimped wire brushes typically are made from carbon, stainless, and brass filaments. The filaments appear wavy or slightly bent to separate them from each other. The crimped brushes last longer because they use oil-tempered wire. However, they are more expensive.
With crimped brushes, you can expect more consistent brushing as most of the action is concentrated at the top of the wire filament.

What to Look for in a Wire Wheel for Rust Removal
It is important to determine what you will be doing with the wire wheel before buying it. If your needs are light and straightforward on everyday tools, then using a crimped brush wire wheel is ideal. However, for professionals or DIY enthusiasts who work heavily corroded metal, the best option is a knotted/twisted brush wire wheel.
On the other hand, you could be doing both light and heavy-duty work, so invest in both types of brushes.
Materials Used in Construction
Most wire wheels are made from metal, but you will come across exceptional options like the KATZCO Rust/Paint Wire Wheel mentioned above, which is made from plastic. Do not only rely on the mention of metal in the construction when purchasing because some metal is poor quality and will break off even sooner than the plastic.
Here is a quick breakdown of the best materials to look out for.
Metal, aluminum, and carbon steel on the body of the unit. Plastic may seem like second best, but the units that use these materials invest in the most premium quality. It is best to use carbon or stainless steel, metal, or aluminum on the filaments/bristles. Some units use nylon on the bristles that can be mistaken to be soft, but it is not, and it reaches even deeper into the corners with a reach that metal and steel cannot achieve.
Speed of the Brush
The higher the RPM on the brush, the more effective it is, right? No. What you should look out for is that the brush can achieve both high and low RPMs. You need a high RPM for heavy-duty work, but if you use the same RPM for light work, you will destroy the metal because the brushwork will be too aggressive.
On the flip side, you will not be effective in doing heavy work using a low RPM. The secret is to buy a wire wheel that gives you the best of both worlds.
Compatibility With Machines
The wire brushes need to be compatible with machines like grinders, drills, and screwdrivers. A wire wheel that is not compatible is actually a useless piece of equipment. Some are only compatible with tools from the same brand. However, choose wire wheels that are not too brand specific but can work with all types of machines, even those from rival brands.
Warranty on the Wheel
A realistic warranty is crucial for these wheels because they are fast wearing, and within no time, they can get ruined if you invest in one with a manufacturer’s defect. Nothing is guaranteed with such equipment. A buyer warranty is also essential when you receive the wheel in pieces.
Most of these units will offer a one year warranty. Established brands like DEWALT also give a 30-day refund policy to buyers for customers who may find the product doesn’t fit their needs.
FAQs About Wire Wheels
Is a Wire Wheel Better Than a Flap Disc for Rust Removal?
The flap disc works well in applications where one is working with a flat and wide surface to clean. However, the wire wheel can reach the nooks and crannies that the flap disc can’t, making it more effective for complicated metal cleaning.
How Do I Install a Wire Wheel on the Angled Grinder?
For the correct installation on an angle grinder you need a flange set to attach to the grinder.
If you are connecting to a bench grinder begin by removing the outer guard on the grinder and then remove the shaft. Buy two flanges one thick for fitting the wheel to the machine itself and a narrower one that attaches to the nut.
The best wire wheel for rust removal not only has a solid build, but it is also a versatile tool. The options above offer the following important features:
- Versatility in use
- Safety features in the construction
- Reasonable pricing
- Brush options
The right wire wheel should offer you the best result for the application you are using it for. Your responsibility is to make sure that you choose the right option for your unique needs.
