13L404 - Walter 4-Inch Knot Twist Wire Wheel Brush with 5/8-11 Arbor

Premium Industrial Wire Wheel Brush

The Walter 13L404 4-inch Knot Twist Wire Wheel Brush is engineered for professionals who demand reliability and performance in surface preparation and finishing. Manufactured by Walter Surface Technologies, a leader in abrasive solutions, this brush is crafted from top-tier quality wire that undergoes rigorous testing to ensure consistency. The defining feature of this model is its impeccable balance. Unlike inferior brushes that may wobble or cause excessive vibration, the 13L404 is perfectly knotted and balanced. This vibration-free operation is critical in industrial settings, as it reduces mechanical stress on power tools and minimizes operator fatigue during prolonged use.

With a diameter of 4 inches and a face width of 3/8 inch, this brush is specifically designed for aggressive cleaning applications. The knot twist construction provides a stiff, high-impact action that effectively removes heavy scale, rust, paint, and corrosion from steel surfaces. It is particularly effective for cleaning pipe welds, where the narrow profile allows the wire tips to penetrate deep into the bead and heat-affected zone. The integrated 5/8"-11 threaded arbor ensures a direct, secure connection to standard angle grinders, eliminating the need for separate adapters and ensuring maximum safety at high RPMs.

Safety and longevity are at the core of the design. The high-grade wire resists premature breakage and flying filaments, creating a safer working environment. Whether used for maintenance, repair, or fabrication, the Walter 13L404 delivers fast removal rates and a long service life, making it a cost-effective solution for heavy-duty material removal tasks. It is an essential accessory for metalworkers requiring precision and durability.
