Bosch Cup Brush - 65mm

This cup brush is primarily used for cleaning stainless steel, aluminum, and non-ferrous metals, including removing coatings, rust, and old paint, as well as for roughing, matt sanding, and texturing.

The brush is designed to fit all angle grinders with an M14 thread.

The crimped wire design is best suited for light- to medium-duty cleaning. For very heavy rust or aggressive material removal, a brush with thicker or different wire material might be more appropriate.

Thicker wires are more aggressive, offering a coarser and faster surface finish. Thinner wires, like the 0.3mm on this model, deliver finer, smoother results.

This feature means the brush is designed to leave a very smooth and clean surface, minimizing imperfections and reducing the need for further finishing steps, which is crucial for applications like painting or welding.

Clean the brush after use by tapping off debris or using compressed air, and store it in a dry place. Inspect for damage before each use.

Ensure the brush is securely tightened to the angle grinder spindle and that the grinder is functioning properly.

Check if the correct wire thickness for the material and desired finish is being used. Ensure consistent pressure and speed during application.

Verify that the brush is properly centered and securely fastened. Inspect the brush for any damage or imbalance.

Reduce the pressure applied during use. Ensure you are using the brush within its intended light- to medium-duty application range.
