A twisted in wire brush is known by many names, including: spiral, tube, flue, bottle, pipe, boiler and power brush. Fundamentally these names all represent the same brush construction, where a piece of wire is doubled over, and fill material is inserted between the fold of the wire stem. The wire stem is then twisted into a brush. Usually, the fill material is made of stainless steel or aluminum, however, the end of the brush can vary considerably depending on your needs. We offer twisted-in-wire brushes with cut tips, rounded tips and filled tips. Our brushes also include the option for a long or short-ended handle, with end ring, loop or cut end to be used with powertools
Typically the fill material is located at one end of the brush, and the handle extends from it. However, the fill can be centered in the wire, with two long ends, one on each side.
