The GSK CUT® 3 Inch Twisted Wire Cup Brush is a professional-grade abrasive accessory engineered for aggressive cleaning and surface preparation on metal surfaces. Manufactured with high-strength knotted steel wire, this wire cup brush delivers excellent durability and consistent performance for demanding industrial, automotive, fabrication, and workshop applications.

Its 3-inch (75mm) cup-shaped design provides maximum contact with flat and slightly contoured surfaces, allowing fast removal of rust, paint, oxidation, corrosion, weld slag, scale, and stubborn contaminants. The twisted (knotted) wire construction offers greater rigidity than crimped wire brushes, making it ideal for heavy-duty cleaning and material removal.

Designed for compatibility with most standard angle grinders, the brush rotates at high speed to efficiently clean metal surfaces while reducing manual effort. The balanced construction minimizes vibration, ensuring smoother operation and better user control during extended use.

The GSK CUT Twisted Wire Cup Brush is suitable for use on steel, iron, cast iron, stainless steel, and other ferrous metals. It is widely used for weld seam cleaning, deburring, paint stripping, rust removal, surface preparation before painting or coating, and general maintenance work in fabrication shops, garages, and industrial environments.

The durable steel wire resists wear and maintains its cutting performance even during prolonged heavy-duty use. Whether you’re restoring old metal parts, cleaning machinery, preparing weld joints, or removing corrosion, this wire cup brush delivers reliable and efficient results.

Note: Always wear appropriate safety equipment and ensure the brush is compatible with your angle grinder’s speed rating before use.
