Lessmann 0.5 Stainless Steel Wire Knot Cup Brush

The Lessmann 0.5 Stainless Steel Wire Knot Cup Brush is a heavy-duty grinder attachment designed for demanding surface preparation tasks on metal. This 65mm diameter cup brush features knotted stainless steel wire construction, making it ideal for professionals working with corrosion-resistant applications where standard carbon steel brushes would be unsuitable. Manufactured by Lessmann, this brush utilises special high tensile strength steel wire to meet the rigorous demands of professional surface preparation work. The stainless steel construction prevents contamination when working on stainless materials and provides excellent corrosion resistance, making it particularly suitable for preparing metal surfaces before painting, removing slag, rust, scale, or concrete waste. The brush features an M14 threaded bore for direct mounting to compatible angle grinders, with 0.50mm gauge wire providing the right balance of aggression and finish quality. With a maximum speed rating of 12,500 RPM, it delivers effective material removal whilst maintaining safe operating parameters. Products marked with an asterisk include a removable bridle that, when removed, exposes an additional 20mm of useable wire for extended service life.
