How to use

Fit the bristle brush into the rotary tool collet according to the tool manufacturer’s instructions and secure it firmly. Start the tool at a low speed and bring the brush gently to the workpiece, increasing speed as needed up to the recommended maximum of 15,000 RPM. Use light, even contact and move the brush across the surface to remove burrs and prepare for polishing. For improved results on metals and jewelry, apply a small amount of polishing compound 421 to the brush or workpiece and continue with light strokes. Avoid excessive pressure or prolonged contact in one spot to prevent overheating or surface damage.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves) and follow your rotary tool manufacturer’s safety instructions. Test on a small, inconspicuous area before treating valuable or delicate items. Do not exceed the specified maximum speed of 15,000 RPM and avoid use on hardened steel surfaces where the brush may wear prematurely.
