Wire cup brush MODECO MN-69-135 steel 100 mm for grinder

MODECO wire cup brush MN-69-135 with steel bristles and 100 mm diameter is a tool designed for surface preparation and heavy-duty cleaning with angle grinders. Its cup shape allows concentrated contact between the wire filaments and the work surface, enabling efficient removal of rust, paint, scale and welding spatter from steel and other ferrous materials. The brush is intended for use with grinders that accept 100 mm cup brushes and standard arbor fittings.

Advantages

The steel bristles provide high abrasion resistance and long service life when used on metal surfaces. The 100 mm diameter offers a balance between coverage and control, making the brush suitable for localized and edge work. The cup design keeps the wires aligned for stable operation and improves material removal rate compared with flat brushes. Compatibility with common grinder arbor sizes simplifies installation and replacement.

Suitable for

• Removing rust and old paint from steel surfaces
• Cleaning weld seams and removing welding spatter
• Deburring and edge preparation on metal parts
• Surface roughening before painting or coating

How to use

Mount the cup brush securely on an angle grinder following the grinder manufacturer's instructions and ensure the tool is disconnected from power during fitting. Wear appropriate personal protective equipment including eye protection, gloves and respiratory protection if necessary. Start the grinder at low speed to check balance, then use steady, even pressure while moving the brush across the work surface. Avoid excessive force or side loading that could deform the wire filaments. Periodically inspect the brush for wear and replace it when bristles are worn, broken or the cup is damaged.

Usage recommendations

Use the brush on clean, dry metal surfaces for best results. Select the appropriate grinder speed recommended for wire cup brushes and avoid exceeding the maximum safe RPM of the brush or the grinder. For non-ferrous metals or delicate surfaces, choose a softer bristle material or a less aggressive brush to prevent surface damage.
