13F310 - Walter 3-Inch Stainless Steel Knot Cup Brush M10x1.25

Technical Precision for Stainless Surfaces

The Walter 13F310 is a premium 3-inch wire cup brush engineered specifically for industrial environments requiring the rigorous cleaning of stainless steel and aluminum components. Featuring a robust knot-twisted wire configuration, this abrasive tool is designed to withstand high-impact applications while maintaining structural integrity. The brush utilizes high-quality stainless steel bristles, which are essential for preventing ferrous contamination on non-ferrous workpieces—a critical factor in maintaining the corrosion resistance of stainless steel post-fabrication.

Integrated with a threaded M10 x 1.25 arbor, this cup brush ensures a secure and balanced connection to compatible angle grinders, minimizing vibration during operation. The 3-inch diameter provides an optimal balance between surface coverage and maneuverability, allowing operators to effectively treat both large flat surfaces and more confined areas. The knot-twisted design offers aggressive material removal capabilities, making it superior to crimped wire alternatives when dealing with heavy scale, thick rust, or stubborn weld spatter.

Walter Surface Technologies manufactures this brush with strict quality control to ensure wire density and balance are uniform. This attention to detail results in a tool that delivers consistent wear rates and extended service life, reducing the frequency of changeovers in high-volume production settings. Whether used for surface preparation prior to welding or for post-weld cleaning and finishing, the 13F310 delivers reliable performance tailored for professional metalworkers.
