![]() But when you’re working with stainless steel or aluminum, you need to use a stainless steel or aluminum brush. ![]() “When you’re working on carbon steel, you use a carbon steel brush. “One of the biggest concerns we hear about is cross-contamination,” Gaspich said. If they aren’t making full contact with the workpiece, they aren’t working efficiently. If the tips aren’t at or near perpendicular as possible with the workpiece, they aren’t making full contact. The tips of the wire do the work, and nothing else. Push down into the bristles below the wire tips, and that scratching sensation goes away, because the tips aren’t making direct contact with your skin. Try gently running your fingers across the tips of those wires, and you’ll of course feel a scratching sensation. Rich Pavlek, technical services engineer for Brooklyn Heights, Ohio-based Osborn, used a soft wire finishing brush to illustrate. “Time and time again, the wire tips are attacking the surface to remove the adherence, be it rust, paint, oxidation, slag, or anything else.” “A wire brush really consists of thousands of little impact tools on the surface of metal,” said Debbie Gaspich, director of product management, thin wheels and construction products North America, at Saint-Gobain Abrasives, Worcester, Mass. When surface material like rust is cleaned with a wire brush, there’s no place on the brush for the particles to accumulate.īefore refining brush selection and technique, it helps to understand how a wire brush actually cleans and deburrs. The brushes won’t last long, simply because they aren’t designed to accomplish the tasks of an abrasive grinding disc.Īlso unlike their coated, bonded, or nonwoven abrasive cousins, wire brushes will not load up with previously ground particles. Sure, it’s possible to work a brush really hard and remove a bit of metal, but it’s not recommended. Unlike a coated abrasive, a wire brush isn’t a metal removal tool. Choosing the right brush for the job and using the right technique can have a dramatic impact on throughput. Like grinding down weld metal with an abrasive disc, though, cleaning and deburring with a wire brush remains by and large an intensely manual process. Brush types abound-wheel brushes, cup brushes, end brushes, and specialty brushes reach into corners and crevices like few other finishing tools can (see Figure 1). ![]() Power wire brushing removes burrs and cleans impurities off various surfaces.

The choice for more aggressive applications requiring higher-impact action and a rougher surface finish.
