## Long description

Unipak Unibrush Cu 28 mm is a circular brush with copper bristles and a 28 mm diameter head designed for surface cleaning, deburring and light metal polishing. Produced by UNIPAK, this brush is intended for use with compatible rotary tools and bench equipment to treat small parts, connectors and contact surfaces in workshop and maintenance environments.
Advantages
The copper bristles provide a balance between abrasiveness and softness, allowing effective removal of oxides, paints and corrosion without aggressive material removal. Its compact 28 mm head gives good access to confined areas and small components while maintaining uniform contact with the work surface. The brush is compatible with a range of handheld and benchtop rotating attachments, offering predictable performance for repeated maintenance tasks.

Brush type: circular/rotary cup style
Primary functions: cleaning, deburring, light polishing
Suitable equipment: compatible with rotary tools and bench-mounted rotary attachments
How to use
Secure the brush in the compatible rotary tool or bench attachment according to the tool manufacturer's instructions. Start at low speed to establish safe contact and increase speed as appropriate for the material and task. Apply light, steady pressure and move the brush across the surface to remove oxides, paint or burrs; avoid excessive pressure or dwell in one spot to prevent surface damage. Periodically inspect the workpiece and the brush for wear and replace the brush when bristles are visibly worn or deformed.
Usage recommendations
Use appropriate personal protective equipment, including eye protection and gloves. For work on electronic contacts, ensure power is disconnected and clean residue is removed after brushing. Test on a small area first to confirm compatibility with the substrate and finish.
