Wire brushes remove rust, paint, scale, weld spatter and slag without changing the shape of the part much. This section covers wire wheels for bench grinders and angle grinders, cup brushes for large surfaces, end brushes for die grinders and tight spots, stringer bead brushes for cleaning between weld passes, and hand scratch brushes. Wire comes in carbon steel, stainless steel and brass, plus abrasive-filled nylon for lighter cleaning.

What to check before you order

  • Crimped or knotted. Crimped wire is flexible and good for lighter cleaning and finishing. Knotted (twisted) wire is stiffer and more aggressive for heavy rust, scale and weld cleaning.
  • Wire material. Use stainless wire on stainless and aluminum so you do not leave carbon steel particles that rust. Brass wire is softer and suits cleaning softer metals and delicate parts.
  • Mounting. Match the arbor hole or threaded hub, such as 5/8"-11 for many angle grinders, and check the shank on end brushes.
  • Speed rating. The brush's maximum RPM must meet or exceed the tool's speed.
  • Protection. Loose wires can fly off at high speed. Wear safety glasses with a face shield and suitable clothing, and follow the manufacturer's instructions and OSHA requirements.

Shop all abrasives, flap and fiber discs, or welding safety gear.

Common questions

Should I use a wire cup brush or a wire wheel?

A cup brush works flat against the part and covers large areas quickly. A wire wheel works with its edge, reaching corners, weld seams and contours.

Why is my wire wheel throwing so many wires?

Too much pressure is the usual cause. Let the wire tips do the work, stay within the brush's rated speed, and replace a brush that sheds heavily.
