Wire cup brush 250 mm diameter, 32 mm bore, steel wire — No name SZ TO 250

Wire cup brush 250 mm diameter with a 32 mm central bore and steel wire filaments designed for surface preparation and heavy-duty cleaning. This brush is intended for use on grinders and compatible drives that accept a 32 mm mounting hole. It is suitable for removing rust, paint, scale and for aggressive deburring and cleaning of metal surfaces in industrial and workshop environments.

Advantages

The steel wire filaments provide high stiffness and abrasion resistance for efficient material removal. Its 250 mm diameter gives a wide working surface, reducing the number of passes needed on flat or large areas. The 32 mm central bore ensures sturdy mounting on compatible spindles and helps maintain concentric rotation for consistent performance. The construction is optimized for mechanical cleaning tasks while offering predictable wear characteristics under normal operating conditions.

Suitable for

• Rust and scale removal on steel components
• Paint and coating stripping from metal surfaces
• Deburring welded joints and machined edges
• Cleaning and surface preparation before painting or coating
• Heavy-duty workshop and industrial brushing tasks

Key specifications

• Brush diameter: 250 mm
• Central bore diameter: 32 mm
• Filament material: steel wire
• Brush type: cup brush
• Primary application: metal surface cleaning and preparation

How to use

Mount the cup brush securely on a grinder or drive that accepts a 32 mm mounting bore, following the tool manufacturer's instructions for fitting and clamping. Ensure the brush is centered and tightened to prevent wobble. Operate the tool at the recommended speed range for wire cup brushes and apply steady, even pressure; avoid excessive force that could deform the filaments or overload the drive. Move the brush across the workpiece in smooth passes, maintaining a consistent angle to achieve uniform surface treatment. After use, allow the brush to come to a complete stop before setting the tool down and inspect the brush for wear or damaged filaments before the next use.

Usage recommendations

Wear appropriate personal protective equipment, including eye and face protection, gloves and respiratory protection if working with dust or paint particles. Use at speeds and with machines rated for cup brushes of this size, and replace the brush when filaments are excessively worn or the cup shows deformation. Store the brush in a dry environment to minimize corrosion of the steel filaments.
