PFERD offers an extensive range of scratch brushes in various shapes and filament materials. Ideal for cleaning spark plugs, small workpieces and tools. 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.
