82342 - Pferd 3-1/2 Inch Stainless Steel Knotted Wire Cup Brush 5/8-11 Thread

Heavy-Duty Stainless Steel Surface Preparation

The Pferd 82342 Knotted Cup Brush is a premium industrial abrasive tool designed for the most demanding surface preparation tasks. Engineered with high-quality .020-inch stainless steel wire, this brush is specifically manufactured to work on stainless steel and aluminum surfaces without introducing ferrous contaminants that could lead to after-rust or corrosion. The 3-1/2 inch diameter provides an optimal balance between surface area coverage and concentrated pressure, making it highly effective for large-scale roughing operations.

This brush features a standard twist knot construction arranged in a single row. This design concentrates the kinetic energy of the rotating wires into a stiff, aggressive cutting action, ideal for removing stubborn materials such as heavy scale, weld slag, concrete residue, and marine growth. The knots are tightly wound to resist flaring, ensuring a consistent cleaning path and extended brush life even under heavy loads. The external nut with a 5/8-11 thread ensures compatibility with a wide range of standard angle grinders, providing a secure and vibration-free connection.

Professionals in metal fabrication, construction, and maintenance rely on Pferd brushes for their consistent performance and safety. The 82342 model excels in cleaning corners, angles, and irregular surfaces where rigid grinding wheels cannot reach. Whether you are prepping a surface for welding, cleaning up after a heavy structural weld, or removing tough coatings, this knotted cup brush delivers the aggressive bite required to get the job done efficiently. Its robust construction minimizes wire breakage, enhancing operator safety and reducing downtime associated with tool changes.

Key Applications:

• Deburring and descaling stainless steel structures.
• Removing weld slag and spatter from heavy fabrication.
• Cleaning concrete forms and removing dried adhesive or mortar.
• Surface preparation prior to painting or coating.
• Maintenance of marine equipment to remove growth and oxidation.
