The individual knot wire tufts of a knot wheel provide minimal flexibility for more aggressive brushing action. Weiler's knot wheels are constructed with an internal steel plate that has equally spaced individual holes around the perimeter. Wire is inserted through each hole and twisted into a knot. Each hole has precisely the same wire count, thereby assuring perfect balance. This eliminates vibration, reduces operator fatigue and increases brush life. Knot wire wheels are available in heat-treated steel, Type 302 stainless steel and bronze wire.
