Buying advice

Consider the type of fill: carbon steel for general purpose, stainless steel for contamination-free finishing, and brass for non-sparking and softer surfaces. Match the brush diameter to your tool's max RPM rating. Knot brushes are more aggressive and last longer, while crimped brushes offer a finer finish. Always wear safety goggles and gloves, as wires can break and fly off.
