Pferd Inc. released a series of 100 percent stainless steel power brushes designated Inox-Total. All components of the brush are produced from 302 stainless steel, making them suitable for environments highly sensitive to contamination, such as the nuclear power and pharmaceutical industries. The brushes are available in a 2-in. stem-mounted crimped wheel, 2-in. stem-mounted knot wheel and 2.75-in. stem-mounted crimped bevel styles for all collet-equipped machines, as well as in a CombiTwist unthreaded knot wheel brush for use on hand-held angle grinders.
