Steel wire brushes really are a common and essential tool in any metal fabrication shop. These brushes can be used as a variety of applications, including weld cleaning, deburring, rust and oxide removal, surface preparation, and surface finishing.
One reason industrial brushes suppliers are extremely commonly used is the fact that, unlike solid abrasive wheels, steel filaments will not likely remove base material or change part dimensions. Wire brushes clean surfaces just like as sandblasting, except that as an alternative to particles of sand colliding with the work surface, wire tips speak to the workpiece. A combination of excellent-quality, hardened steel wire tips with all the energy of high surface speeds enables the brushes to separate surface contaminants from base material.
Steel brushes also are versatile, with many different configurations open to meet the criteria of every application. By way of example, brushes with long filaments are conformable capable to follow contoured surfaces, and short trim brushes are fast-acting and suited for severe applications. Another variable will be the fill density: Low-density brushes offer good flexibility for surface cleaning operations on irregular surfaces, and high-density brushes produce a fast brushing action and long brush life.
Furthermore, steel brushes are nonloading. Quite simply, they actually do not become clogged with particles and debris when used to remove paint and other coatings.

Perhaps because wire brushes are this type of familiar item, they are really easy to overlook and sometimes receive insufficient attention. However, five tips may help you boost the performance and lifespan of your own wire brushes.
1. Take advantage of the Highest Safe Speed
Power wire brushes, like cutting tools, operate most effectively once the speed and pressure in the operation properly match the demands of your application. In most operations, utilizing the highest speed using the lightest possible pressure will make sure the quickest brushing action and longest brush life.
Increasing brush speed towards the highest safe speed improves the face stiffness and brushing action. A fine-wire brush rotating at a high-speed often produces exactly the same results like a coarse-wire brush rotating at a slow speed, however it generally lasts longer. Therefore, you are going to reach the lowest production costs by utilizing the finest wire which will do the job.
In case the brush speed is insufficient, frustrated operators typically apply more pressure (see Figure 1). However, excessive pressure causes overbending of your filaments and heat buildup, causing filament breakage, rapid dulling, and reduced brush life.
As an alternative to applying greater pressure, try using a brush with more aggressive action, for example one by using a larger filament diameter or a shorter filament trim length, a treadmill using a knot type as opposed to crimped wire. Or you can try increasing brush surface speed by increasing rotations per minute (RPM) or brush diameter.
You’ll need to determine the correct operating speed for every single application. For safety, it really is imperative to never exceed the most safe free speed (MSFS) or RPM rating that this manufacturer publishes for each and every type of brush.
Figure 1Excessive pressure causes over bending from the filaments, contributing to filament breakage, rapid dulling, and reduced brush life.
2. Periodically Reverse Direction
To improve the performance and extend the lifespan of wire wheel brushes without nuts, like the brushes popular on a bench grinder, this is a easy and quick tip: Periodically reverse the direction of rotation to benefit from the self-sharpening action which will result (see Figure 2).
To reverse the direction of rotation, simply get rid of the brush through the spindle, flip the wire brush 180 degrees, and remount the brush securely.
3. Know What sort of Wire to utilize
Crimped-wire brushes are general-purpose brushes that can be used for a selection of applications. They are made of hard-drawn wire that is certainly crimped allowing individual filaments to back up the other. Crimped-wire brushes provide flexibility for light- to medium-duty brushing action, and they will be utilized on parts that might be damaged through the impact of a knot brush.
Knot-wire brushes (see Figure 3) are made from heat-treated straight wire filaments twisted as being a single unit resembling some cable or wire rope. They provide less flexibility and more aggressive brushing action than crimped brushes in heavy-duty applications on parts that need high-impact action. Knot-wire brushes frequently are employed in welding applications and to remove large burrs and high contamination, such as multiple layers of rust, scale, paint, or oxides.
4. Keep Steel Brushes Clean
Steel brushes often are employed on stainless-steel and aluminum and also other nonferrous metals to remove the possibility of “after-rust” appearing about the work surface. By using simple practices, it is possible to maximize the strength of these power tools.
As soon as you work with a stainless-steel brush on carbon steel, usually do not apply it to stainless steel because after-rust may appear. To stop contamination, store all stainless brushes from places that carbon steel particles might come in contact with the brushes, for example steel workbenches.
As opposed to a well known misconception, a stainless-steel brush wire is magnetic. Because of this, enough time-tested practice of employing a magnet to examine whether steel is stainless or carbon does not work on brushes. The drawing process, which is used to make brush wire, causes the information to be interested in a magnet. The effects of your drawing process could be eliminated by heating the wire using a match until it might be red-hot. In case the wire is Type 302 stainless, it does not be attracted to a magnet after heating.
For critical operations, degrease stainless steel wire brushes before beginning the operation. If you’ll be storing the brushes after use, degrease them and wrap them in plastic. In the event you store the brushes without protection for almost any time period, their magnetic properties might cause the brushes to collect foreign matter, leaving after-rust when reused.
5. Use Heat-treated, 47dexqpky Steel Wire
Although stainless has the benefit of eliminating after-rust, carbon steel is superior inside the critical attributes of cutting action and fatigue resistance. When purchasing carbon steel brushes for industrial applications, it is very important buy ones that have filaments created from high-quality material. Look for heat-treated, oil-tempered or heat-treated, high-tensile steel, specially in wire diameters of .008 inch and greater.
You can aquire twisted wire tube brushes in the neighborhood home improvement store or do-it-yourself retailer, but in the long term, you could turn out spending more as a consequence of reduced productivity, more changeover time, and brush replacement costs. By way of example, a $5 brush might last one hour, whereas a $10 brush will likely last over a day.
