Koppbørster

Koppbørster, also known as cup brushes, are a type of wire brush designed for use with angle grinders and other power tools. They are characterized by their cup-like shape, which allows them to cover a wider surface area than a standard wheel brush. The bristles, typically made of steel, brass, or stainless steel, are arranged in a way that provides effective cleaning, stripping, and deburring.

The primary function of a koppbørste is to remove rust, paint, scale, and other debris from metal surfaces. They are commonly used in metal fabrication, welding, automotive repair, and general maintenance tasks. The aggressive nature of the bristles, combined with the high rotational speed of power tools, makes them efficient for heavy-duty cleaning.

Koppbørster come in various sizes and thread sizes to fit different tools and applications. The type of bristle material is important; steel is the most common and durable for aggressive work, while brass is softer and suitable for less demanding tasks or to avoid scratching softer metals. Stainless steel bristles are used when corrosion resistance is a priority, especially in industries like food processing or chemical manufacturing.

Safety precautions are essential when using koppbørster. Eye protection, hearing protection, and gloves are mandatory due to the potential for flying debris and the noise generated. Proper handling and maintenance of the brush and tool are also crucial for preventing accidents and ensuring optimal performance. Overuse or damage can lead to bristle shedding or breakage, posing a safety hazard.
