Walter 5-Inch Crimped Wire Cup Brush with Safety Ring

Smooth Cleaning for Weld Prep and Finishing

For professional welders, surface preparation is half the battle. The Walter 5-inch Crimped Wire Cup Brush (SKU: 13E504) is your go-to solution for cleaning large steel surfaces before and after welding. Unlike twisted knot brushes that are designed for heavy-duty impact and slag removal, this crimped wire brush offers a smoother, more flexible action. It is perfect for stripping away rust, old paint, and light mill scale without digging deep into the base metal. This makes it an excellent choice for preparing plate steel for welding or for cleaning up heat discoloration and spatter on larger weldments where a consistent surface finish is required.

What sets this brush apart in your tool kit is the integrated safety supporting ring. We've all used brushes that flare out like a mushroom after just a few uses, making them useless for getting into corners or maintaining pressure. The Walter ring keeps the wires tight and focused, giving you a dense brushing face that works faster. But the real bonus comes when the wire wears down: instead of tossing the brush, you simply knock off the supporting ring to unleash a whole new layer of wire length. It's like getting two brushes in one, saving you money and trips to the tool crib.

Designed with a standard 5/8"-11 threaded arbor, this cup brush spins right onto your 5-inch, 6-inch, or larger angle grinder. The balance is superb, meaning less wobble and less fighting the grinder at the end of a long shift. Whether you are cleaning up a repair job on heavy equipment, stripping paint off a frame, or prepping structural steel, the Walter 13E504 gives you the control and longevity you need to get the job done right. Note: This brush uses carbon steel wire and is intended for use on carbon steel; for stainless steel work, be sure to switch to a stainless wire brush to prevent contamination.
