A wire brush is a brush instrument whose bristles are constructed of metal, often steel wire. The steel used is usually a mix of medium to high carbon and very stiff and springy. Other wire brushes, based on use, have bristles made of brass or stainless steel. Epoxy, staples, or other binding can keep wires together in a wire brush. Wire brushes are typically either wooden or plastic handles (for lightweight use) or molded into a circle for angle grinders, desk grinders, pistol-grip drill motors, or other control instruments.
Wire brushes are a great choice for scraping corrosion and decay, dust, slag, weld splatter and other unwanted surface particles with angle grinders, bench grinders or drills. For surface painting, washing and polishing, weld mixing, deburring, and elimination of resin, corrosion, size, or other pollution, wheel brushes offer straight line brushing action. Wheel brushes are ideal for use with different types of handheld grinders, desk grinders, robotic finishing equipment or for mounting in a manufacturing process onto a powered arbor. The wire brush is essentially an abrasive tool, used for rust cleaning and paint removal.
Various types of wire wheel brushes are available but the device selection starts with an understanding of the basic modes of wire wheel: crimped and knotted.
Crimped Wire Wheels
Crimped wire wheel brushes show filaments of wavy, twisted or pinched carbon steel, stainless steel or brass. Crimping separates these metal filaments from each other and helps reduce the rigidity of the wire and the breakage of the wire caused by flexing, turning and traveling. Crimped wheels built from oil-tempered wire can cost more, but are usually longer to last. Small pieces of wire fall off during routine use of the wheel knife, which leave fresh cutting edges uncovered. Crimps help in making breaks cleaner.
Many crimped wire wheels have a 2 “arbor hole that allows use with 1/2” or 1 “shafts. Such wire wheel brushes are available in a variety of sizes but the most common diameters are 6 to 8 inches. The component or work piece base material dictates which filament sort to choose, and the filament or wire size is a feature of the finishing specifications. Another essential to remember is the mask distance, so producers can choose to be short, medium, broad or extra-large. Narrower brush faces are suitable for uneven textures, corners and crevices. Wider faces of the brush provide continuous brushing over larger areas.
Knotted Wire Wheels
Knotted wire wheel brushes feature metal wire ties or loops, usually carbon steel or stainless steel. We help vigorous hacking and withstand twisting and movements which can contribute to exhaustion of the metal. Regular or twisted tuft brushes are twisted for around two-thirds of the duration of the filament.
The remaining third gets slightly flared. The loops can be twisted over their entire length for greater wire sizes and applications that need heavy brushing action. Such knotted brushes of the wire wheel are classified as cable twists and are often used in oil pipelines and oil fields. This is used for surface painting of narrow channels and grooves and for pre-welding preparation of pipes. Unlike crimped wire wheel brushes with a small face, stringer bead brushes have longer trimming to finish uneven corner and crevice surfaces.
