13W441 - Walter Allsteel 4-Inch Knot Wire Bevel Brush 5/8-11

Heavy-Duty Cleaning for Hard-to-Reach Angles

The Walter Allsteel 4-Inch Knot Saucer Brush (13W441) is a premium industrial abrasive tool designed to tackle the toughest surface preparation and cleaning challenges in metal fabrication. Part of Walter's renowned Allsteel™ line, this brush is engineered specifically for working with steel, offering exceptional durability and performance that professionals rely on. The unique "saucer" or bevel shape is a critical innovation, bridging the gap between flat wire wheels and cup brushes. This angled design allows the operator to work comfortably in tight corners, fillet welds, and irregular surfaces where traditional brushes often struggle to maintain contact.

Constructed with high-grade carbon steel wire, the twist knot design provides an aggressive cutting action necessary for removing heavy contaminants. Whether you are dealing with thick rust, stubborn paint, weld slag, or mill scale, the 13W441 delivers the impact force needed to strip surfaces clean down to the bare metal. Walter Surface Technologies prioritizes operator safety and comfort; every brush is meticulously balanced to ensure vibration-free running. This reduction in vibration not only extends the life of the angle grinder but also significantly reduces operator fatigue during prolonged use, leading to safer and more productive work environments.

The integrated 5/8-11 threaded arbor ensures a direct, secure, and spin-on fit for most standard 4.5-inch and 5-inch angle grinders. This eliminates the need for separate adapters and ensures the brush remains centered and stable at high RPMs. For fabrication shops, shipyards, and structural steel plants, the Walter Allsteel Knot Saucer Brush is an indispensable tool for ensuring weld integrity and surface cleanliness.

Key Industrial Benefits

• Aggressive Material Removal: The twisted knot wires act like miniature impact hammers, breaking away hard scale and slag efficiently.
• Corner Access: The beveled profile is specifically optimized for cleaning inside 90-degree angles and fillet welds without gouging the base metal.
• Long Service Life: Premium wire metallurgy resists premature breakage and wear, offering excellent value per brush.
