Rotec gang brush, twisted steel wire, M14, Ø 65 x 0.35

With twisted steel wire, the wires are twisted together into small strands. Such a brush is stiffer and more aggressive than a brush with loose, crimped wire. This makes it work faster on stubborn dirt, but it is also less suitable for fine work.

What kind of work is twisted steel wire suitable for?

Twisted wire is intended for heavy-duty work on steel and other hard metals. Think of removing rust, mill scale, weld spatter and thick layers of old paint. For soft materials, painted surfaces or delicate parts, a finer brush or a different method is usually better, because twisted wire can leave scratches.

How to choose an M14 wire cup brush for steel

First check the connection: M14 must match the spindle of your machine. Then look at the diameter and wire thickness. Thicker wire is sturdier and more aggressive, thinner wire is more flexible and adapts better to the surface. Also check the maximum speed stated on the brush or in the product information, and always stay within it.

Working safely with a wire brush

When brushing, loose wire strands and dirt particles can be flung off. Therefore, always wear safety glasses or a face shield, gloves and hearing protection. Clamp the machine firmly, do not apply too much pressure, and let the wires do the work. Excessive pressure causes wear and can cause the wires to break.
