48H435 - Walter Saucer-Cup Brush 4-1/2" Knot-Twisted Carbon Steel

Heavy-Duty Surface Preparation with Walter Technology

The Walter Surface Technologies Saucer-Cup Brush represents a significant evolution in wire brush design, engineered specifically for the rigorous demands of industrial metalworking and welding applications. Unlike traditional cup brushes, this unit features a unique saucer (bevel) shape that allows operators to access tight corners, fillets, and irregular surfaces that standard flat brushes simply cannot reach. Built with high-grade carbon steel wire, this brush is designed for aggressive material removal, making it an essential tool for cleaning welds, removing heavy scale, and preparing surfaces for coating or inspection.

Safety and performance are at the core of Walter's engineering. This brush is meticulously balanced to ensure smooth operation, significantly reducing vibration. Lower vibration levels not only protect the angle grinder's bearings and gears from premature wear but also reduce operator fatigue, allowing for longer, more precise work periods without discomfort. The knot-twisted wire configuration provides a stiff, high-impact face that cuts through rust, paint, and slag with efficiency, ensuring a clean substrate without removing base material unnecessarily.

Durability is a hallmark of the Walter brand. The wires are securely anchored to prevent premature breakage, a common issue with inferior brushes that creates safety hazards. Whether you are working in a fabrication shop, a pipeline site, or a maintenance facility, the Walter Saucer-Cup Brush delivers consistent performance. It attaches easily to standard 4-1/2 inch angle grinders via a 5/8"-11 threaded arbor, making it a versatile addition to any professional tool crib.

Key Applications

• Weld Cleaning: Effectively removes slag, spatter, and oxidation from fresh welds, ensuring a clean surface for subsequent passes or inspection.


• Surface Prep: Ideal for stripping rust, paint, and corrosion from steel structures prior to painting or coating.


• Deburring: Quickly removes burrs from cut edges and machined parts.


• Corner Access: The saucer shape permits cleaning in 90-degree angles and intricate geometries where flat cup brushes fail.
