2 1/2 x 1/4 Crimp End Brush

2 1/2 x 1/4 Crimp End Brush.  These brushes are used in paint and rust removal from metal.  They will not mar the material as much as grinding wheels or even knotted wire brushes.  They have a 1/4" round shank that will fit most any drill or die grinder.  Check the RPM's before using with your die grinder.
