13C370 - Walter 3-Inch Mounted Wire Cup Brush for Steel

Industrial-Grade Surface Preparation

The Walter 13C370 3-Inch Mounted Wire Cup Brush is a premier choice for industrial professionals requiring reliable and aggressive surface cleaning. Engineered by Walter Surface Technologies, a leader in abrasive solutions, this brush is designed to withstand the rigors of heavy-duty environments. The brush features high-quality carbon steel wires that are meticulously crimped and anchored to ensure maximum density and safety. This construction allows for rapid removal of surface contaminants such as rust, loose paint, and corrosion while maintaining a long service life.

One of the standout features of this mounted cup brush is its exceptional balance. Vibration is a common issue with inferior wire brushes, leading to operator fatigue and uneven wear on power tools. Walter has addressed this by precision-balancing every unit, ensuring smooth operation even at high rotational speeds. This makes the 13C370 particularly suitable for use with die grinders and power drills, providing the operator with precise control over the cleaning process. The 3-inch diameter offers a significant contact area, making it efficient for cleaning broader flat surfaces or slightly curved parts found in manufacturing and maintenance operations.

Safety and durability are at the core of the design. The wires are treated to resist fatigue and breakage, reducing the hazard of flying wires—a common concern in metalworking shops. Whether you are preparing a surface for coating, cleaning up after machining, or restoring metal parts, this brush delivers consistent results. It is specifically optimized for use on steel, ensuring that the wire hardness matches the workpiece for effective material removal without gouging the base metal.

Key Applications:

• Removing heavy rust and scale from structural steel.
• Stripping paint and coatings from metal surfaces.
• Cleaning castings and molds in industrial settings.
• General maintenance and repair operations (MRO).
