Aggressive and robust brush that is able to withstand high mechanical loads. Ideal for heavy-duty brushing in pipeline and container construction. The patented thread design prevents the brush from coming into contact with the protective cover of the angle grinder. Steel wire is the most common filament material. Brushes with steel wire as the filament material are ideal for work on surfaces and deburring. PFERD special wire has high tensile strength and bending fatigue strength. This ensures that the wire wears down in the optimal way, as well as a long tool life, even in extreme brushing applications. Steel wire is temperature-resistant up to 600°F.
