Wheel brushes provide straight line brushing action, for surface finishing, cleaning and polishing, weld blending, deburring, and removal of paint, rust, scale, or other contamination. Wheel brushes are appropriate for use with various types of hand-held grinders, bench grinders, robotic finishing equipment, or for mounting onto a driven arbor in a production process. Spiral Brush manufactures a broad line of wheel brushes, ranging from small diameter copper center wheel brushes to large wide face brushes that are capable of being gang-mounted on a common drive shaft. Most wheel brush styles may be filled with crimped wire or a variety of synthetic or natural fibers. Twisted knot wheels are filled with straight wire that is twisted to various specifications (2/3 twist, cable twist, or stringer bead) to provide progressively higher levels of brushing action control and aggressiveness of cutting action.
