kwb Crimped HSS Steel Wire Cup Brush, 50 mm Diameter, 6 mm Shank, for Drills and Cordless Screwdrivers, 4500 RPM 602433

This cup brush is built around crimped HSS steel wire, which delivers aggressive rust, paint, and deburring action while remaining controllable on drills and cordless screwdrivers. The 50 mm cup diameter and 6 mm cylindrical shank fit common chucks, and the 4500 RPM maximum speed matches the performance range of typical power tools.

Highlights

• Crimped HSS steel wire for effective surface preparation
• 50 mm cup diameter for balanced coverage and control
• 6 mm shank for secure mounting in drill chucks
• Rated up to 4500 RPM for fast material removal
• Suitable for metal, wood, stone, and plastic

In daily use

The crimped wire pattern reduces vibration compared to twisted wire, making it easier to guide the brush across flat or contoured surfaces. Use it for removing rust, old paint, or burrs before welding or repainting. The cup shape allows work on edges and corners, while the 0.3 mm wire thickness balances aggressiveness with surface finish.
