Ingco WB21251 Wire Cup Brush 125mm M14/2 Twisted Steel

Our review

This is a cup-shaped twisted wire brush from Ingco, the WB21251, sized at 125mm with an M14/2 thread. The working part is steel wire twisted into bundles, which is the stiffer, more aggressive style of brush rather than a crimped one. It is meant to be mounted on an angle grinder and used for stripping varnish and paint and for cleaning rust from metal surfaces and products. That makes it a sensible pick for someone doing heavier surface preparation, such as cleaning up old steel before repainting, rather than for light finishing work where a softer crimped brush would leave a gentler surface. Before buying, check that your grinder's spindle thread matches the M14/2 fitting and that the 125mm diameter suits your machine and the space you are working in. Also think about what you are cleaning: twisted knots bite harder and can mark softer metals, so compare this with a crimped cup brush if you want a finer result. Safety gear matters with any wire brush, since loose strands can fly. The brush is available on Sokonia.
