Brushes consist of a filament stuck between two metal wires twisted together. The result is a helix-shaped brush (brush at HELIX SIMPLE ).
If the brush is mounted on a mechanical device, generally the metallic stem is sliced from both sides. If the use is manual, on the one hand leaves a stem portion free from the filament to be used as a handle, generally terminating with a circular ring or welding manichetto plastic.
The end of the brush can be folded and made a small fan-shaped filaments called ” fan- tip ” that is designed to prevent wire damage the veneer pieces to work with. To this end can be achieved also a closed toe with ring terminal or with the material that fills it until the end. When you request a particular strength, the brush can be built with four-wire seal, which can fit a threaded connection M12.
The main feature of the brushes is the small diameter of the core, which makes them irreplaceable for the internal cleaning of pipes , conduits and interstices of difficult access. Also one can exploit their flexibility for cleaning curved surfaces.
