i know this is an old thread. ill comment anyway.
i have noticed over the years it seams harder and harder to buy real quality products. i have used wire brushes and twist brushes. the speed ratings match my angle grinder. and they still fly apart. i tried a fan speed motor controller to slow down my angle grinder and drill. so far with limited trialing ,it appears the lower speeds are going to help brushes hold together.
