Forney Welding Knotted Wire Cup Brush

The Forney Welding Knotted Wire Cup Brush is a power-tool accessory for aggressive surface preparation and cleaning. Use it on an angle grinder or similar rotary tool. It removes rust, scale, paint, weld slag, and corrosion. Other common names include knot-twist cup brush, twist knot wire cup brush, and wire cup wheel.

Key Features:

• Knotted wire construction: The wire filaments are twisted into tight knots or bundles. This gives the brush more cutting power and stiffness than a crimped wire brush, so it works well on heavy buildup.
• Cup brush design: The cup shape puts the wire face and edge in contact with the work. This helps with large flat surfaces, edges, and weld seams.
• Durable steel wire: The tough wire resists breakage and holds up in demanding shop, fabrication, and maintenance work.
• Threaded arbor mount: The brush threads directly onto compatible power tools for a secure fit.
