UNIPAK brush Unibrush Cu 22 mm model 4312022 – copper filament round brush

UNIPAK Unibrush Cu 22 mm (model 4312022) is a round wire brush with a 22 mm filament diameter and copper (Cu) wires designed for controlled surface cleaning and light material removal on metal parts. The compact round shape fits into tight areas and works with compatible rotary tools and small bench grinders to perform precision cleaning, deburring and preparation of metal surfaces before finishing or assembly.

Advantages

The copper filament offers a balance between flexibility and abrasion for delicate metal finishing without aggressive scratching. The small 22 mm round head allows access to confined spaces and gives good control for spot work and edge treatment. Constructed for consistent wire distribution, the brush provides even cleaning action and reduced vibration when used with recommended speeds. It is intended for workshop and maintenance tasks where controlled, non-aggressive material removal is required.

Suitable for

• Precision cleaning of metal parts and components
• Removing light rust, corrosion and paint residues
• Deburring and edge blending on thin or soft metals
• Surface preparation before soldering, painting or coating
• Maintenance and repair tasks in automotive, metalworking and electronics workshops

Key specifications

• Brush shape: round
• Filament material: copper (Cu) wire
• Working diameter: 22 mm
• Intended use: rotary tools and small bench grinders (compatible devices)
• Typical applications: surface cleaning, light rust and paint removal, deburring, delicate finishing

How to use

Install the UNIPAK Unibrush Cu onto a compatible rotary tool or bench grinder following the tool manufacturer’s mounting instructions. Operate at the recommended speed range for wire brushes to avoid excessive filament wear and to maintain control. Apply light to moderate pressure and move the brush steadily across the surface; avoid pressing hard to prevent deformation of the wire filaments and the underlying material. Inspect the workpiece frequently and replace the brush when wires are worn or splayed to maintain consistent performance.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Avoid using the brush on delicate plated finishes or highly polished surfaces without testing on a small area first. Keep the tool speed within recommended limits for wire brushes and follow general workshop safety rules to minimize risk of injury and damage.
