OVERVIEW

Heavy-Duty Surface Preparation with Walter Surface Technologies

The Walter 13G554 Knot Twist Cup Brush is a premium abrasive tool designed for the most demanding surface cleaning applications. Engineered by Walter Surface Technologies, this 5-inch cup brush features robust knot-twisted bristles made from high-quality, oil-hardened, and tempered carbon steel wire. The .020-inch wire diameter ensures aggressive cutting action, making it the tool of choice for removing heavy encrustations, slag, rust, and paint from large steel surfaces.

What sets this model apart is its integrated safety support ring. This metal ring surrounds the wire knots, preventing them from flaring out prematurely under centrifugal force and pressure. As the wire wears down, the ring maintains a tight brush face, ensuring consistent aggression and significantly extending the usable life of the tool. Once the wire wears down to the ring, the ring can often be removed to expose the remaining wire length, maximizing value.

Designed for balance and safety, every Walter cup brush is individually balanced to run smoothly on angle grinders. This reduces vibration, protecting both the power tool's bearings and the operator's hands from fatigue during long shifts. The 5/8"-11 threaded arbor ensures a secure and quick attachment to most standard North American angle grinders. Whether you are working in a shipyard, a fabrication shop, or on a pipeline, the 13G554 delivers the reliability and performance professionals expect from Walter.

Key Technical Benefits

Aggressive Removal: Knot twist design concentrates force for digging out deep rust and scale.
Controlled Wear: The support ring keeps wires tight, preventing dangerous fly-offs and extending life.
Vibration Free: Precision balancing ensures smooth operation at high RPMs.

FAQ

The safety ring prevents the wire knots from flaring out under rotation. This maintains a dense brushing face for aggressive cleaning and prevents premature wire breakage, significantly extending the brush's life.

It is designed for angle grinders with a standard 5/8"-11 threaded spindle. It is typically used on 5-inch, 6-inch, or larger grinders rated for the brush's RPM.

No, this brush uses carbon steel wire. Using it on stainless steel can cause 'after-rust' or contamination. You should use a stainless steel wire brush (typically with blue hubs from Walter) for stainless applications.

While always check the stamp on the actual product, 5-inch cup brushes like the 13G554 are typically rated for around 8,600 RPM.

Yes, the aggressive knot twist design is excellent for removing old paint, coatings, and heavy corrosion from steel surfaces.

The wire diameter is .020 inches, which is a heavy-gauge wire suited for aggressive material removal.

Replace the brush when the wires are worn down significantly or if the brush becomes unbalanced. If the ring is removable, you may be able to remove it to utilize the remaining wire length before disposal.
