Walter 3-Inch Stainless Steel Knot Cup Brush M10x1.25

Heavy-Duty Cleaning Power

Tackle the toughest cleaning jobs in the shop with the Walter 3-inch Knot-Twisted Stainless Steel Cup Brush. Built for welders and fabricators who demand durability, this brush is a powerhouse when it comes to prepping surfaces and cleaning up after the bead is laid. If you are working with stainless steel or aluminum, using the right brush is non-negotiable; this stainless steel wire brush ensures you don't introduce rust-causing contaminants into your base metal, keeping your welds clean and compliant.

The knot-twisted wire design acts like a set of impact hammers, aggressively chipping away heavy corrosion, thick paint, and tenacious weld spatter that standard crimped brushes just glide over. It is the ideal tool for deburring cut edges or cleaning root passes and cap passes in multi-pass welding applications. The M10 x 1.25 thread mounts quickly and securely to your grinder, giving you a balanced, smooth-running tool that reduces operator fatigue during long shifts.

Don't let scale or spatter slow down your workflow. The Walter 13F310 is designed to cut fast and last long, providing a consistent finish without the rapid wire loss seen in cheaper alternatives. Whether you are cleaning up a custom aluminum fabrication or prepping stainless pipe for a sanitary weld, this cup brush provides the aggressive action needed to get down to bare metal quickly and efficiently.
