How to use

Install the 3.2 mm shank into the rotary tool collet and secure it according to the tool manufacturer's instructions. Start the tool at a low speed to position the brush on the workpiece, then increase speed as required up to the maximum of 15,000 RPM. Apply light, even pressure and move the brush steadily to avoid concentrating abrasion in one spot. Replace brushes as they wear to maintain consistent performance.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves and dust mask) and ensure the rotary tool is compatible with a 3.2 mm shank and the specified maximum speed. Test on a spare piece before working on the final surface to confirm the finish.
