🛠️ Bristle Cup Brushes – M14 for Angle Grinders

115mm diameter Bristle cup brushes with M14 thread are designed for efficient deburring, cleaning, paint removal, and surface finishing using standard angle grinders. These abrasive cup brushes feature flexible moulded bristles that provide consistent surface contact while reducing the risk of damage to the base material.

Built with aluminium oxide abrasive grain embedded in durable polymer bristles, these cup brushes deliver reliable cutting performance throughout their working life. Their flexible design allows them to reach irregular shapes and hard-to-access areas, making them suitable for professional fabrication, maintenance, and industrial finishing tasks. 

⚙️ M14 Direct Mount for Angle Grinders

These bristle cup brushes are fitted with an integrated M14 thread, allowing direct installation onto standard angle grinders without additional adaptors or flanges. This ensures fast setup and stable operation during use.

📏 Available Grit Sizes

Bristle cup brushes are available in multiple grit sizes to suit different levels of material removal and surface finishing including:

• P50 grit — Coarse grade for aggressive cleaning and rust removal
• P80 grit — Medium grade for general deburring and preparation
• P120 grit — Fine grade for smoother finishing and surface refinement

The abrasive grain is colour-coded for easy identification of grit size during use.

🔧 Typical Applications

M14 bristle cup brushes are widely used across fabrication, engineering, and maintenance environments where controlled finishing is required.

Common applications include:

• Removing paint and coatings
• Deburring sharp edges
• Cleaning metal surfaces
• Removing rust and oxidation
• Breaking sharp edges
• Surface preparation before painting
• Cleaning round and irregular workpieces
• Structuring and finishing metal components

Their flexibility makes them particularly effective on irregular or complex surfaces where traditional wire brushes may be less effective.
