Wire cup brush MODECO MN-69-134, steel, 80 mm — for angle grinders and rotary tools

MODECO MN-69-134 is a steel wire cup brush with an 80 mm working diameter designed for surface preparation and removal of rust, paint and scale. Made for use with angle grinders and compatible rotary tools, this cup brush delivers aggressive mechanical cleaning on metal and other hard surfaces. It is suitable for deburring, edge cleaning and weld seam preparation where consistent brushing action and material removal are required.

Advantages

The steel wire construction provides high abrasion resistance and efficient removal of corrosion, coatings and mill scale. The 80 mm diameter offers a balance between coverage and control for use on small to medium workpieces. The cup shape maintains a stable brushing plane for even surface treatment and improved access to edges and contours. Designed for compatibility with standard angle grinders and many rotary tools, the brush enables rapid cleaning while preserving workpiece geometry when used correctly.

Suitable for

• Removing rust, old paint and scale from metal surfaces
• Deburring cut or machined edges
• Preparing weld seams and exposed joints for finishing
• Cleaning metal parts, tools and fixtures prior to coating or painting

Key specifications

• Brush type: steel wire cup brush
• Working diameter: 80 mm
• Intended tools: angle grinders and compatible rotary tools
• Primary applications: rust, paint and scale removal; deburring; weld seam preparation
• Brush geometry: cup shape for stable contact and edge access

How to use

Mount the cup brush on a compatible angle grinder or rotary tool following the tool manufacturer's instructions and ensuring the spindle and thread sizes match. Securely tighten the attachment and check that the brush spins freely without wobble before starting. Operate the tool at the recommended speed range for the brush and apply steady, moderate pressure—let the wire filaments do the cutting; excessive force can reduce brush life and damage the workpiece. Move the brush across the surface with uniform strokes, maintaining an angle appropriate to the task for efficient material removal while avoiding concentrated gouging.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Inspect the brush before each use for loose wires or deformation and replace if damaged. Avoid using the brush on soft or highly polished surfaces where scratching is unacceptable. For optimal life and performance, match rotational speed to the brush’s safe operating range and store the brush in a dry environment to prevent premature corrosion.
