13W551 - Walter Allsteel 5-Inch Knot Wire Wheel with 5/8-11 Hub

Heavy-Duty Weld Cleaning and Prep

Maximize your welding preparation and post-weld cleanup efficiency with the Walter Allsteel 13W551 Knot Wheel Brush. Designed for professional welders who demand reliability and aggression, this 5-inch wire wheel features a robust twist knot design that excels at removing heavy slag, spatter, and oxidation from steel surfaces. The "Allsteel" formulation ensures that you get a long-lasting brush that maintains its cutting action even under heavy pressure, making it a staple in any welding rig.

The 13W551 is equipped with a standard 5/8"-11 threaded hub, allowing for fast, spin-on installation on most 4.5-inch and 5-inch angle grinders. This secure connection eliminates the need for separate locking nuts and ensures the wheel stays centered for smooth operation. The knotted wire configuration is significantly more aggressive than crimped wire, making it the ideal choice for the initial pass on rusty metal or for cleaning multi-pass welds where slag inclusions must be thoroughly removed. The 3/8-inch width provides excellent access to fillet welds and tight angles without sacrificing stability.

Vibration is the enemy of precision and comfort. Walter addresses this by ensuring every Allsteel brush is dynamically balanced. This attention to detail results in a smoother running tool that reduces stress on your grinder's bearings and lowers the risk of hand-arm vibration syndrome for the operator. By choosing the Walter 13W551, you are investing in a consumable that offers consistent wire stiffness and breakage resistance, ensuring a safer work environment and a cleaner weld zone every time. It is the perfect companion for stick and flux-core welding applications where slag removal is frequent.
