How to use

Mount the cup brush securely in a compatible rotary tool or drill with a 6 mm chuck. Start at low speed to align the brush and then increase speed as appropriate for the material and task. Apply light, even pressure and move the brush across the surface to remove rust, paint or deposits; avoid excessive force to prevent wire breakage and damage to the workpiece. For interior shapes and narrow areas, work incrementally and reposition the tool to reach confined spots.

Recommendations

Use personal protective equipment including eye protection, gloves and a dust mask. Check the brush before each use for loose wires or damage and replace if necessary. Match brush speed to the tool and the material; consult the rotary tool manual for maximum safe RPM for 2.5 cm cup brushes and observe safe operating practices.
