Wire Brush (Wheels and Cups)
Wire brushes are intended to “clean” structural steel, castings, sheet metal, stone, and concrete. They are used to remove rust, scale, and paint.
1.Allow the tool to reach full speed before touching the tool to the work surface.
2.Apply minimum pressure to the work surface, allowing the tool to operate at high speed.
3.Continuously move the tool at a moderate speed to avoid creating gouges in the work surface.
4.Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before laying it down.
Tip: The tips of the brush do the work. Operate wire brushes with the lightest pressure so only the tips of the wire come in contact with the work piece. If heavier pressures are used, the wires will be overstressed, resulting in a wiping action and a shortened brush life due to wire fatigue. Applying the side or edge of the brush to the work piece will result in wire breakage and shortened brush life. (Fig. 24)
