Wire cup brush MODECO MN-69-122 for grinder, 150 mm diameter, steel wire

Wire cup brush MODECO MN-69-122 for grinder, 150 mm diameter, steel wire is an abrasive accessory made for use with angle grinders. With a 150 mm working diameter and steel wire filaments, the cup brush is designed to clean metal surfaces, remove rust and old paint, deburr edges and prepare parts for welding or painting. It mounts to the grinder’s spindle and provides broad surface contact for efficient material removal on flat and contoured metal workpieces.

Advantages

The steel wire construction delivers consistent aggressiveness and durability for medium to heavy-duty surface preparation tasks. The 150 mm diameter offers a balance between coverage area and control, allowing operators to work more quickly than with smaller rotary brushes while maintaining manageable handling on an angle grinder. The cup shape holds filaments securely and provides even wear, helping to extend service life under regular use.

Suitable for

• Removal of rust and scale from steel surfaces
• Paint and coating removal on metal components
• Deburring and edge blending on cut or welded parts
• Surface preparation before welding, priming or painting

Key specifications

• Working diameter: 150 mm
• Brush type: cup brush
• Filament material: steel wire
• Mounting: grinder spindle attachment
• Typical applications: surface cleaning, rust removal, paint stripping, deburring

How to use

Attach the cup brush securely to the angle grinder following the grinder manufacturer’s instructions and ensure the spindle lock and nut are tightened. Operate the grinder at the recommended speed range for wire brushes, hold the tool with both hands, and apply light, even pressure while moving the brush across the work surface. Avoid excessive pressure or side loading that could deform filaments or reduce brush life. Always let the brush reach full speed before contacting the workpiece and finish passes with steady, overlapping strokes for uniform results.

Usage recommendations

Use appropriate personal protective equipment — safety goggles, face shield, gloves and hearing protection — and secure loose clothing and long hair. For painted or coated surfaces, work in a well-ventilated area and consider dust extraction or a respirator to limit inhalation of particles. Regularly inspect the brush for excessive wear or wire loss and replace when performance declines or safety is compromised.
