321311or Wire Cup Brush, 3 In. Dia, 1/4 In. Arbor

The Vulcan 321311OR is a 3-inch diameter wire cup brush designed for fast, efficient cleaning and material removal on wood, metal, and plastic surfaces. This coarse-grade brush is made with tough, durable carbon steel wire that resists wear and maintains its shape even under heavy-duty use, making it ideal for removing paint, rust, and scale in metalworking, automotive, fabrication, and general maintenance applications. The 1/4-inch arbor fits standard power-tool spindles, providing versatile compatibility across most machines and drill presses.

Whether you're preparing surfaces for finishing, restoring weathered materials, or performing routine maintenance in a workshop or job site, this wire cup brush delivers consistent, reliable performance. Its open-circuit cup design promotes coolant flow and helps prevent excessive heat buildup during operation, which extends equipment life and reduces maintenance costs. The balanced construction also minimizes vibration, providing smoother operation for extended use.
