Cup brush KWB 606210

The KWB Cup Brush 606210 is a crimped HSS steel-wire cup brush with a 6 mm shank and a 50 mm cup diameter, designed for cleaning, derusting and surface preparation on metal and stone. It is suited to medium and large-area work where removal of scale, paint or coatings and texturing or matt finishing is required.

Advantages

The crimped high-speed steel wires provide a balance of abrasion and flexibility for effective removal of rust, paint and scale while maintaining brush shape. The 6 mm shank fits common rotary tools and drills, and the compact 50 mm cup allows access to edges and moderate recesses. The construction offers consistent performance on both metal and stone surfaces and is appropriate for preparing surfaces before painting or welding.

How to use

Mount the cup brush securely in a compatible rotary tool or drill with a 6 mm chuck. Run the tool at the manufacturer-recommended speed for wire brushes; apply steady, even pressure and move the brush across the work surface to remove rust, paint or scale. Avoid excessive side pressure or impact that can deform the wires. Periodically inspect the brush for wear and replace when wires are significantly worn or damaged.

Recommendations

Use appropriate personal protective equipment: safety glasses, gloves and a dust mask. Test on a small inconspicuous area first to confirm surface effect. Do not use the brush on delicate finishes or soft materials where wire abrasion could cause damage.
