Crimped wire wheels provide greater flexibility, conform better on irregular surfaces and are less aggressive than knot or stringer wire wheels. Crimped wire wheels are commonly used for cleaning/deburring, surface preparation, rust/oxide removal and coating removal.
Knot wire wheels are less flexible and more aggressive than crimped wire wheels. Knot wire wheels are commonly used for surface preparation, rust/oxide removal, coating removal and weld cleaning. Knot wire wheels also work great on applications requiring high impact.
Stringer bead wire wheels are similar to knot wire wheels but have thinner and tighter knots making it an even better choice for use on high impact applications. Stringer bead wire wheels are commonly used in tight areas, corners and root pass weld cleaning.
