are a common Power Brush
configuration and are further categorized as crimped wire or knot compositions. Crimped wires produce a fine finish and are composed of steel (carbon and stainless) and brass variants. They are fabricated in different wire sizes and diameter widths and are commonly employed for blending, cleaning and polishing purposes. According to experts they can be used as individual tools or together as a unit to create a wider brush area surface. Knot wheels are comprised of metal filaments that are conformed, or twisted together to create a strong, abrasive action when they are operated by a power tool. These wheels are commonly used in heavy, abrasive removal applications, such as to remove scale and weld. They can be joined in multiples, or stacked to achieve greater width and coverage. Wheel Brushes
vary in size and application use, (e.g., single handed grinders and larger vacuum applications).
