13G604 - Walter 6" Knot-Twisted Cup Brush with Ring, Steel .020"

Aggressive Cleaning Power for Tough Jobs

When you are staring down a large steel plate covered in heavy scale, rust, or thick paint, you need a brush that bites back. The Walter 13G604 6-inch Knot-Twisted Cup Brush is built exactly for these heavy-duty applications. Unlike standard crimped brushes that just polish the surface, the knot-twisted design of this brush delivers a high-impact cleaning action that rips through contaminants to expose bare metal quickly.

Built to Last Longer
One of the biggest frustrations with wire brushes is how quickly they flare out and lose their effectiveness. Walter solved this with their innovative safety support ring. This metal ring holds the twisted knots tight, preventing them from spreading out too early. This means you get a more concentrated, aggressive cleaning action for much longer. Once the wire wears down to the ring, you simply knock the ring off to unleash a fresh length of wire, effectively giving you a second life on the same brush.

Perfect for Weld Prep and Cleanup
This brush is an essential tool for any welder's arsenal. Use it for pre-weld surface preparation to ensure a contaminant-free base material, or for post-weld cleaning to remove stubborn slag and spatter. The .020" steel wire is tough enough to handle structural steel work, tank fabrication, and shipyard maintenance. It mounts easily to your 6-inch or larger angle grinder with a standard 5/8"-11 spindle, giving you the power to clean large areas efficiently.
