Wire cup brush MODECO MN-69-164 80 mm — rotary wire brush for grinders

MODECO MN-69-164 is an 80 mm wire cup brush designed for surface preparation and cleaning with angle grinders and compatible rotary tools. The brush features a dense arrangement of wire bristles shaped in a cup form to provide consistent contact with curved and flat metal surfaces. It is intended for workshop and industrial maintenance tasks where removal of rust, paint, scale and burrs is required, as well as for light surface blending and finishing.

Advantages

The wire cup construction ensures uniform abrasion across a broad contact area and improves stability during rotation. Dense, short bristles deliver aggressive material removal while reducing the risk of excessive chatter or gouging on workpieces. The compact 80 mm diameter offers improved access in constrained spaces compared with larger cup brushes, while maintaining effective cleaning performance on small to medium-sized components. The brush is compatible with standard angle grinders and rotary tools that accept cup-style attachments and the appropriate arbor.

Suitable for

• Removing rust and loose paint from metal surfaces
• Eliminating scale and oxidation on steel parts
• Deburring edges and weld seams
• Surface blending and light finishing before painting or coating
• Cleaning small machine parts, fittings and metal components

Key specifications

• Brush type: cup-shaped rotary wire brush
• Diameter: 80 mm
• Bristle material: steel wire (densely packed)
• Suitable drive: angle grinders and compatible rotary tools with matching arbor
• Application: rust, paint, scale removal, deburring, surface finishing

How to use

Secure the cup brush to the grinder or rotary tool following the tool manufacturer’s instructions and ensure the arbor fits correctly. Wear appropriate personal protective equipment including eye protection, gloves and respiratory protection when needed. Start the tool at low speed to confirm secure mounting and then work at the tool’s recommended operating speed. Apply moderate, even pressure and move the brush across the surface to remove rust, paint or burrs; avoid excessive force which can deform the bristles or damage the workpiece. Allow the brush to cool periodically during extended use.

Usage recommendations

Use the 80 mm cup brush for localized cleaning and finishing tasks where access is limited. Match the wire type and tool speed to the material being processed; for delicate surfaces consider testing on a scrap piece first. Replace the brush when bristles are worn or when performance decreases to maintain consistent results and safe operation.
