How to use

Install the cup brush securely in the tool’s chuck or spindle according to the power tool manufacturer’s instructions and ensure the shank (1.4 cm) is clamped firmly. Operate the tool at appropriate speed for twist-knot steel wire brushes, apply steady, even pressure and move the brush across the work surface. Avoid excessive pressure or lateral forces that can damage the wire knots or the substrate. Use appropriate coolant or intermittent passes when working on heat-sensitive surfaces to prevent overheating.

Recommendations

Wear suitable personal protective equipment including eye protection, gloves and respiratory protection when working with steel wire brushes. Check the tool and accessory for damage before use and follow the maximum speed ratings of both brush and power tool. Do not use on highly polished finishes or delicate materials.
