Wire cup brush Smart 100 mm braided disc, bent type for angle grinders

Wire cup brush Smart 100 mm braided disc, bent type for angle grinders is a purpose-built rotary cleaning tool designed for robust surface preparation on metal. With a 100 mm diameter and twisted (braided) wire filaments arranged in a bent profile, this cup brush combines aggressive material removal with stable performance for tasks such as rust and paint stripping, deburring and weld cleaning. It mounts to standard angle grinders and is intended for professional and workshop maintenance use where high abrasion and durability are required.

Advantages

The braided wire construction delivers high mechanical strength and sustained cutting action, reducing wear compared with loose-wire designs. The bent profile enhances contact area and improves access to irregular or contoured surfaces while helping to maintain consistent pressure distribution during operation. The 100 mm diameter provides a balance between working width and tool control, enabling efficient material removal without excessive vibration when used at recommended speeds.

Suitable for

• Removing rust, old paint and scale from metal surfaces
• Deburring edges and removing sharp burrs after cutting or machining
• Cleaning welding seams and preparing joints for inspection or finishing
• Surface preparation before painting, coating or adhesive bonding
• General metal maintenance in workshops, fabrication and repair environments

Key specifications

• Brush type: braided (twisted) wire cup brush
• Profile: bent filament configuration for improved contact
• Diameter: 100 mm working diameter
• Compatibility: designed for use with angle grinders having matching arbor/connectors
• Filament material: steel wire suitable for aggressive metal cleaning
• Intended use: heavy-duty surface preparation on ferrous metals

How to use

Securely fit the cup brush to the angle grinder following the tool manufacturer’s instructions and ensure all guards and fastenings are correctly installed. Operate the grinder at the recommended speed range for the brush and apply consistent, moderate pressure—allow the twisted wire filaments to do the cutting rather than forcing the tool. Move the brush evenly across the workpiece, keeping the grinder at a shallow angle to avoid gouging soft materials. After use, clean debris from the brush and inspect filaments for excessive wear or damage before the next application.

Usage recommendations

Use appropriate personal protective equipment including eye and face protection, gloves and hearing protection. Avoid using the brush on non-ferrous or soft materials where wire filaments may cause surface damage. Replace the brush if wires become significantly worn, splayed or broken to maintain safe and effective performance.
