Wire cup brush MODECO MN-69-114 steel 150 mm for angle grinder

MODECO wire cup brush MN-69-114 with 150 mm diameter and steel bristles is designed for attachment to angle grinders for heavy-duty surface cleaning and preparation. The steel construction and cup shape concentrate abrasive action for removing rust, paint, welding scale and other firmly adhered residues. This accessory is intended for use in metalworking, renovation and maintenance where fast material removal and surface roughening are required prior to painting, coating or further processing.

Advantages

The steel wire bristles deliver aggressive cutting action and long wear life on metal surfaces while the cup design provides stable contact with the workpiece during high-speed rotation. The brush is compatible with angle grinders that accept 150 mm cup brushes, offering efficient removal of corrosion, old coatings and burrs. Its construction supports consistent surface profiling and preparation, helping to reveal sound base material and improve adhesion for subsequent treatments.

Suitable for

• Rust and scale removal from steel structures and parts
• Paint and coating removal on metal surfaces
• Cleaning weld seams and removing welding slag
• Deburring and edge preparation on fabricated metal components
• Surface roughening before priming or painting

Key specifications

• Brush type: cup brush with steel wire bristles
• Diameter: 150 mm
• Material of bristles: steel
• Intended tool: angle grinder compatible with 150 mm cup brushes
• Typical application: aggressive material removal, surface preparation and deburring on metal

How to use

Mount the cup brush on an angle grinder following the grinder manufacturer's instructions and ensure the grinder is unplugged or the battery is removed during installation. Verify the brush is securely fastened and that the maximum safe speed of the brush matches the grinder's rated speed. When operating, hold the grinder with both hands, apply steady pressure and move the brush across the surface at a consistent angle to avoid gouging. Use smooth passes and let the bristles do the work rather than forcing excessive pressure, which can reduce brush life and increase heat build-up.

Usage recommendations

Use personal protective equipment, including eye protection, gloves, and respiratory protection when producing dust or fumes. Avoid contact with non-metal surfaces and soft alloys that may be damaged by steel bristles. Inspect the brush before each use for excessive wear or loose wires and replace if damaged. Operate within recommended speed limits and maintain a controlled motion to achieve uniform results and prolong accessory life.
