Walter 3-Inch Stainless Steel Wire Cup Brush with 5/8-11 Arbor

Heavy-Duty Cleaning for Stainless Fabrication

When you are finishing a stainless steel weld or prepping aluminum for fabrication, you need a wire brush that won't contaminate your base metal. The Walter 3-Inch Stainless Steel Cup Brush (13G314) is built for exactly that. It features high-grade stainless bristles that aggressively remove slag, spatter, and oxidation without leaving behind carbon deposits that could ruin your pass or lead to future corrosion. It is the perfect companion for your 4.5-inch or 5-inch angle grinder.

We know that vibration is the enemy of a long shift. Walter has dynamically balanced this cup brush to run smoothly, saving your hands and wrists from the fatigue of a wobbling tool. The crimped wire design is excellent for covering large, flat areas quickly, while the built-in supporting ring keeps the wires tight and focused. This means the brush doesn't just splay out and stop working; it digs in and cleans effectively for the entire life of the product.

Safety is also a major priority. The supporting ring helps prevent wire breakage and fly-off, keeping you safer while you work. Whether you are cleaning up a tank, polishing a railing, or just removing shop grime, this brush threads on in seconds and stands up to the heat and abuse of daily welding work. Stop wasting time with cheap brushes that shed wire and wear out in minutes—upgrade to Walter for a smoother, safer grind.
