Cup brush Bosch 2 608 622 006 Diameter 5 cm Wire thickness 0.3 mm

The Bosch cup brush with a 5 cm diameter and 0.3 mm wire thickness is designed for surface preparation and cleaning tasks. Intended for use with compatible rotary tools and angle grinders, this cup brush removes rust, paint, scale and other surface contaminants from metal and prepared surfaces. The compact 5 cm diameter offers controlled material removal in confined areas while the 0.3 mm wire gives a balance between aggressiveness and finish quality.

Advantages

This cup brush delivers consistent brushing performance and uniform contact on flat and slightly contoured surfaces. The 0.3 mm wire thickness provides efficient removal of corrosion and paint without excessive gouging on standard steel surfaces. The small diameter improves access to tighter spots and helps maintain control during operation. Designed for professional and DIY settings, the brush is suitable for repetitive cleaning tasks and targeted surface preparation.

Suitable for

• Removing rust and scale from steel and iron components
• Stripping paint and coatings from metal surfaces
• Cleaning weld seams and preparing joints for welding or painting
• Deburring and edge blending on small parts
• General metal surface preparation in maintenance and repair work

How to use

Mount the cup brush securely on a compatible rotary tool or angle grinder following the tool manufacturer’s instructions. Verify that the brush is correctly seated and tightened before starting the tool. Begin operation at low speed to check balance and clearance, then increase to the recommended operating speed for your tool and the task at hand. Apply firm, even pressure and move the brush across the surface; avoid excessive pressure which can reduce brush life and damage the workpiece. After use, allow the brush to come to a complete stop before setting the tool down and inspect the brush for wear or deformation.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, gloves, and hearing protection. Ensure the chosen wire thickness and brush diameter match the workpiece and task to achieve the desired finish while minimizing substrate damage. Replace the brush if wires are significantly worn or uneven to maintain safe and effective performance.
