Twisted Wire Brushes
Twisted wire brushes are an important brushing tool for industry. Commonly known as test tube, bottle or tube cleaning brushes.
Twisted wire brushes are made by taking (2) or (4) round wires, placing filaments between them and twisting them tightly thus securing brush filaments between the wire.
Twisted Wire Brushes Come In (3) Basic Styles:
- Single Stem – Single Spiral: Brush bristles are twisted between (2) stem wires with a single stem wire on each side of the fill wire.
- Double Stem – Single Spiral: Brush bristles are twisted between (4) stem wires with two stem wires on either side of the fill wire.
- Double Stem – Double Spiral: Brush bristles are twisted between (4) stem wires with two layers of fill material. Fill material layers are perpendicular to each other.
Twisted Wire Brush Specifications
Twisted wire brushes besides being available in the (3) basic constructions Single Stem – Single Spiral, Double Stem – Single Spiral and Double Spiral – Double Spiral and also available with different stem ends, tip ends, stem material, fill material and trim shapes.
Stems can be made of steel, stainless steel, brass and vinyl coated steel depending on your needs and application.
Tip End of Brush
The tip end of the brush can be done in different methods depending on the application. The end can be cut, continuous end (bent in half to start). The ends of the brush can be manufactured, bridled or banded (tied to stand upon the end) or bent as a turned end or a rosebud end to give a brushing surface at the end of the brush. The tip of the brush can be dipped in epoxy so it does not have a sharp end to cut or cause damage to a substrate. The ends of a brush can have an eye mounted for a push pull system.
Handle or Stem End of Twisted Wire Brush
The handle end of a brush (end of brush opposite the hair face) can be a bare stem made of the twisted stem wire to chuck on and rotated or can be manufactured with a wood, metal or plastic handle on the end. The end can also have a loop or eye for hand applications. The brushes can be supplied with a pipe nipple so extension handles can be mounted to the brush thus extending the reach of the brush.
Twisted wire brushes can be trimmed in many shapes other than the traditional round brush. The brushes can be trimmed conical, concave, convex, tapered, square or rectangular depending on your application.
