Angle cup brush 120 mm with M14 thread, steel wire — No name SZ TK 120 ST

Angle cup brush 120 mm with M14 thread and steel wire filaments is a rotating abrasive tool designed for use with angle grinders. The cup shape and dense steel wire bristles provide effective removal of rust, scale, paint and other surface contaminants from metal parts, weld seams and castings. With a 120 mm diameter it covers moderate surface areas while the M14 threaded arbor ensures secure mounting on compatible grinders.

Advantages

The steel wire filaments deliver aggressive cleaning and rapid material removal on stubborn corrosion and mill scale while maintaining shape for consistent performance. The cup design allows stable contact with flat and slightly contoured surfaces, improving efficiency compared with smaller wheel brushes. Compatibility with M14-mount grinders makes installation straightforward and reduces vibration during operation when correctly secured.

Suitable for

• Removing rust and scale from steel and iron surfaces
• Cleaning weld seams and joint preparations
• Paint and coating removal from metal parts
• Surface preparation before welding or painting
• Deburring and general metal surface cleaning

Key specifications

• Brush type: Cup brush with steel wire filaments
• Diameter: 120 mm
• Filament material: Steel wire for aggressive abrasion
• Mounting: M14 threaded arbor for angle grinders
• Suitable speed range: Compatible with standard angle grinder rotational speeds (observe grinder limits)

How to use

Mount the cup brush onto an angle grinder with an M14 arbor following the grinder manufacturer’s instructions and ensure the tool is powered off during fitting. Tighten securely and check that the brush runs true before applying power. Hold the grinder with a firm two-handed grip and apply the brush to the workpiece at a shallow angle with light to moderate pressure, allowing the filaments to do the work. Move the brush steadily across the surface to avoid gouging. After use, allow the brush to stop spinning completely before setting the tool down and inspect bristles regularly for wear or damage.

Usage recommendations

Use appropriate personal protective equipment including safety goggles, face shield, gloves and hearing protection. Match brush size and wire hardness to the task, and avoid excessive pressure or side loads that can accelerate wear or present safety risks. Do not use on non-ferrous metals if wire shedding or surface scratching is a concern. Replace the brush when bristles are significantly worn, bent or missing.
