Diamond-Coated Brushes for Mill Scale Removal

Aug. 28, 2019


PFERD diamond-coated wire brushes are ideal for removing localized heavy mill scale prior to welding in hard to reach areas. They are also ideal for other heavy-duty surface conditioning applications, as well as for blending machining marks and generating distinct scratch patterns. The brushes can be used on all metals, such as steel, stainless steel (INOX), and aluminum. Additionally, they can also be used on composite, carbon fiber and glass workpieces for surface conditioning applications.


The brushes feature industrial diamond that is electroplated onto stainless-steel knot wire strands. The stainless-steel wires are then twisted into knots available in wheel and cup brush configurations with the following dimensions: 2-3/4 in. OD cup brush with 5/8-11 in. thread, 4 in. OD cup brush with 5/8-11 in. thread, 7-1/2 in. OD wheel brush with 1-1/4 in. ID arbor hole. They are available in 400 (fine) and 270 (coarse) options.


The stainless-steel wire does not contaminate the workpiece, and all diamond-coated wire brushes are degreased to further assure contaminant-free use. They are designed for use on variable speed right angle grinders and other popular power tools found in most fabrication facilities. They have extended knot flag length, providing flexibility on uneven surfaces and complex geometries. The loosely twisted knots cover a large surface area, and they exhibit a good balance between aggressiveness and flexibility. For full effectiveness, the brush speed should not exceed 3,000 rpm.
