Cup brush Bosch 2609256516 5 cm diameter 6 mm shank

The Bosch 2609256516 cup brush has a 5 cm diameter and a 6 mm shank, designed for cleaning and surface preparation on metal and other materials. The brush uses brass-coated wire, which combines the mechanical cleaning performance of steel-wire brushes with added corrosion protection from the brass coating, making it suitable for tasks where reduced sparking and mild surface polishing are beneficial.

Advantages

The brass-coated wire offers corrosion protection while maintaining effective removal of rust, paint and scale. The 5 cm cup shape ensures good contact with flat and slightly contoured surfaces, and the 6 mm shank fits standard rotary tools and drills. The brush provides reliable mechanical cleaning performance with lower risk of contaminating treated surfaces compared to bare steel wire.

Suitable for

• Removing rust and old paint from metal surfaces
• Surface polishing and deburring on steel and non-ferrous metals
• Cleaning weld seams and preparing metal for further treatment
• Light surface conditioning on wood and composite materials

How to use

Install the cup brush on a compatible rotary tool or drill with a 6 mm chuck. Secure the shank and check that the brush is mounted straight before operation. Operate at the speed recommended by the tool manufacturer; avoid excessive pressure—let the brush do the work—to prevent premature wear and potential damage to the workpiece. Move the brush evenly across the surface for consistent cleaning or polishing results.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, gloves and a dust mask. Test the brush on a small, inconspicuous area first to verify the effect on the material. Avoid use on very soft or highly finished surfaces where abrasion by wire bristles could cause unwanted damage.
