Walter Allsteel 2-3/8 Inch Mounted Stainless Steel Cup Brush

Keep Your Stainless Welds Rust-Free

As a welder, you know that using a carbon steel brush on a stainless steel weld is a recipe for disaster. Tiny iron particles can embed themselves in the stainless surface, leading to rust streaks and failed inspections down the road. The Walter Allsteel 2-3/8" Mounted Cup Brush S/S is your solution for safe, effective cleaning of stainless steel assemblies. Built with high-grade stainless steel bristles, this brush ensures that the passive layer of your stainless material remains uncompromised by ferrous contaminants.

This brush is designed to mount directly into your die grinder, giving you portable, high-speed cleaning power right where you need it. The 2-3/8 inch diameter is the perfect sweet spot—large enough to clean areas quickly, but compact enough to maneuver around fixtures and flanges. The cup style is excellent for scrubbing flat surfaces and getting into corners where a flat disc might dig in. It effectively removes weld spatter, slag, and the rainbow heat tint often seen after TIG or MIG welding stainless steel.

Walter Surface Technologies is known for producing brushes that hold their wire longer and vibrate less. This means you can work smoother and safer. The balanced shaft ensures the brush spins true, preventing the "hopping" that can ruin a finish or strain your wrist. Add this essential tool to your welding bag to ensure your stainless projects stay stainless.
