How to use

Secure the brush in a compatible rotary tool or grinder with a 1.4 cm chuck. Operate at the tool manufacturer’s recommended speeds for twisted-knot steel brushes, apply consistent light-to-moderate pressure, and move the brush steadily across the work surface. Avoid excessive pressure or side loading to prevent premature wear and to maintain safe operation. Stop periodically to check progress and remove debris.

Recommendations

Use appropriate personal protective equipment, including eye and face protection, gloves and respiratory protection if dust is generated. Follow the tool and brush manufacturer's safety guidelines and recommended operating speeds. Test on a small area if material compatibility is uncertain.
