Dremel manufactures three kinds of wire brushes. These are made of carbon steel, stainless steel and brass. Each wire brush has a 1/8-inch diameter shank, or shaft, designed to be used in an electrically-powered rotary tool at up to 15,000 revolutions per minute (RPMs). The heads of the wire brushes have diameters from 1/8 to 3/4 inch.
Carbon Steel Brushes
The Dremel carbon steel wire brushes are numbers 428, 442 and 443. You can use them to clean and remove rust and corrosion from small items made of brass, copper and other soft, ferrous metals. These items include door knobs, tools, parts from automobiles and electrical contacts and components. Further, you can use them to polish metal surfaces with or without a polishing compound.
Stainless Steel Brushes
Stainless steel Dremel wire brushes are numbers 530, 531 and 532. You can use them to clean small objects made of stainless steel, aluminium, silver, pewter and other white metals. These objects include stainless steel cutlery, aluminium engine parts, old silver coins and pewter tankards. Do not allow your stainless steel brushes to become contaminated with carbon steel particles as this may lead to rusting.
Brass Wire Brushes
Numbers 535, 536 and 537 are the Dremel brass wire brushes. You can use them to clean small objects made of gold, bronze, copper or brass. These objects include old gold coin, bronze goblets, copper piping and brass ornaments and keys. You can also use them to finish your own projects, such as models and artistic pieces. In other words, give them a soft, satin or matt finish.
All Dremel Wire Brushes
You can use Dremel wire brushes to create different decorative effects on coarse-grained wood like oak and ash. You can also use them to deburr your own projects. In other words, to remove the extraneous sharp edges or raised imperfections caused by other metalworking processes. The wire brushes are very effective on flat surfaces, such as name plates and drink coasters. They are also useful for cleaning slots, such as engine vents and grilles.
