How to use

Secure the cup brush to a compatible angle grinder according to the grinder manufacturer’s instructions and ensure the machine is switched off when fitting. Wear appropriate personal protective equipment (glasses, gloves, dust mask) and start the grinder at low speed to check stability. Apply steady, even pressure and move the brush across the surface to remove rust, paint or scale; avoid excessive force or tipping to reduce wire breakage. After use, disconnect the power and inspect the brush for wear before storing.

Use the KWB 719206 cup brush on suitable substrates only (metal, stone). Match brush diameter and wire thickness to the task and tool speed, and replace the brush when wires become heavily worn or damaged. Follow all safety instructions for angle grinders and wear eye, hand and respiratory protection during operation.
