Excellent for surface structuring work on large workpieces. 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. This brush is made with brass-plated carbon steel wire. This special wire construction is ideal for heavy-duty brushing and aggressive brushing.
