Polax wire cup brush M14 125 mm, brass bristles

The Polax wire cup brush M14 125 mm with brass bristles is a tool for surface preparation and light finishing on metal and other hard materials. Designed to fit angle grinders with an M14 arbor, this 125 mm cup brush provides controlled removal of rust, paint, scale and burrs while improving surface texture for subsequent welding, painting or coating. Brass bristles reduce the risk of sparking and are softer than steel, making the brush suitable for delicate surfaces where aggressive abrasion is not desired.

Advantages

This wire cup brush offers a balanced combination of effective cleaning and reduced surface aggressiveness due to brass bristles. The M14 thread ensures compatibility with common angle grinders that accept this arbor size, enabling quick installation and secure attachment. The 125 mm diameter delivers sufficient working area for faster coverage while remaining manageable for detailed tasks. The brush design promotes controlled material removal with consistent performance and extended service life when used within recommended speeds.

How to use

Mount the Polax wire cup brush on an angle grinder with an M14 arbor according to the grinder manufacturer's instructions, ensuring the tool is disconnected from power during fitting. Hold the grinder firmly with both hands and run the brush at the grinder's recommended operating speed, applying light to moderate pressure. Move the brush across the work surface with steady, even strokes; avoid excessive force or side loading that can deform the bristles or reduce effectiveness. For thin or delicate materials, test on a small area first to confirm the appropriate pressure and feed rate.

Usage recommendations

Use appropriate personal protective equipment: eye protection, gloves, hearing protection and a dust mask where necessary. Avoid exceeding the maximum RPM rating of the brush and follow the grinder manufacturer's safety guidelines. Store the brush in a dry place to prevent contamination and inspect the bristles before use; replace the brush when bristles become excessively worn or damaged to maintain safe and effective operation.
