09C404 - Walter Allsteel 4-Inch Knot Twist Wire Wheel Brush

Heavy-Duty Surface Preparation with Walter Allsteel

The Walter Allsteel 4" X 1/2" Knot Twist Wheel (SKU: 09C404) is a premium industrial wire brush designed for the most demanding surface cleaning applications. Engineered by Walter Surface Technologies, this tool represents the pinnacle of wire brush construction, utilizing high-grade carbon steel wire that maintains stiffness and cutting aggression throughout the life of the product. The "Allsteel" series is specifically formulated for use on steel and other ferrous metals, making it an essential consumable for fabrication shops, shipyards, and structural steel environments.

What sets the 09C404 apart is its meticulous manufacturing process. Each wheel is individually balanced to ensure perfect concentricity. This attention to detail eliminates the vibration often associated with standard wire wheels, protecting both the power tool's bearings and the operator's hands from fatigue. The knot twist design bundles the wires into tight, twisted tufts, providing a high-impact action that easily breaks through heavy slag, thick rust, and stubborn paint coatings. Unlike crimped wire wheels which are better for light surface finishing, this knot twist wheel is built for material removal and heavy-duty prep work.

With a 4-inch diameter and a 1/2-inch face width, this wheel is compact enough to maneuver into corners and along weld seams while still providing substantial coverage. It is an ideal solution for deburring cut edges, cleaning root passes in multi-pass welds, and preparing surfaces for painting or coating. Professionals rely on Walter's consistent quality to reduce downtime caused by premature brush failure or wire breakage.

Technical Excellence and Safety

Safety is paramount in high-speed grinding operations. Walter's manufacturing ensures that wire filaments are securely anchored, significantly reducing the risk of wire fly-off compared to lower-quality alternatives. The 09C404 is designed to run smoothly at high RPMs, delivering consistent performance from the first use to the last. Whether you are removing spatter after welding or cleaning up a repair area, this wire wheel delivers the reliability required for industrial MRO tasks.
