OVERVIEW

Aggressive Weld Cleaning for Hard-to-Reach Areas

Welders know that the hardest part of cleaning a weld is often reaching it. The Walter 13H504 5" Saucer Cup Brush is designed specifically to solve this problem. With its distinctive saucer shape and 45-degree angle, this brush fits perfectly into fillet welds, corners, and tight angles where slag and spatter love to hide. It bridges the gap between a standard cup brush and a wire wheel, giving you the best of both worlds for post-weld cleanup.

This brush features heavy-duty knotted twist wire, which provides the aggression needed to rip through stubborn slag, heavy spatter, and oxidation. The knotted design prevents the wires from bending back prematurely, delivering a concentrated cleaning action that exposes defects and prepares the metal for the next pass or final finishing. It is specifically formulated for use on steel, making it a staple for structural welding and heavy fabrication.

Vibration is the enemy of precision and endurance. Walter has engineered this brush to run smoothly on your angle grinder, minimizing the "jumping" often associated with aggressive wire brushes. This stability allows you to clean welds with precision, ensuring you don't damage the surrounding area while removing contaminants. The 5/8"-11 threaded hub spins on and off your grinder in seconds, keeping your downtime to a minimum.

Don't struggle with brushes that can't reach the job. Upgrade to the Walter Saucer Cup Brush for your root passes, cap passes, and general surface prep. It’s built tough to handle the heat and abuse of the welding shop, ensuring you get a clean surface every time.

FAQ

The saucer cup shape features a 45-degree angle, which allows the brush to access tight corners, fillet welds, and irregular contours that standard flat cup brushes cannot reach.

No, this brush uses carbon steel wire. Using it on stainless steel can cause cross-contamination and lead to rust. You should use a stainless steel wire brush (typically marked with blue packaging or specified as SS) for stainless applications.

This brush has a 5/8"-11 threaded arbor, making it compatible with most standard 4.5-inch and 5-inch angle grinders.

Knotted wire is twisted into tight bundles, making it stiffer and more aggressive for heavy-duty cleaning. Crimped wire is wavy and flexible, better for light cleaning and surface finishing.

The maximum safe operating speed is typically 12,500 RPM for this 5-inch brush. Always check the stamp on the brush itself to confirm before use.

Yes, absolutely. Wire brushes can throw loose wires and debris. Always wear a face shield, safety glasses, gloves, and protective clothing when operating wire brushes.

Yes, the aggressive knotted wire is very effective at removing old paint, coatings, and primer from steel surfaces.

Apply only light pressure; let the wire tips do the work. Excessive pressure bends the wires, causing fatigue and premature breakage.
