Knot Cup Brush: overview

Knot cup brushes combine the aggressive action of knotted wire with a cup shape that covers flat surfaces quickly. They mount directly on an angle grinder and are used for heavy rust, scale and paint removal on large areas.

Choosing the right size

Check the arbor or thread size of your grinder or drill, then never exceed the brush’s maximum RPM. Knotted (twisted) wire is more aggressive; crimped wire is more flexible and gives a finer finish.
