83284 - Pferd 1-1/8" Knot Wire End Brush .014 Stainless Steel 1/4" Shank

Precision Weld Cleaning for Stainless Steel

For professional welders working with stainless steel, the Pferd 83284 Knot Wire End Brush is an essential accessory for post-weld cleanup and inter-pass cleaning. When welding in tight corners, T-joints, or inside piping, standard cup brushes and wheel brushes often cannot reach the heat-affected zone effectively. This end brush bridges that gap, offering a compact 1-1/8 inch profile that fits where bulkier tools cannot. The aggressive knot wire design powers through heavy slag and oxidation, exposing clean metal without removing excessive base material.

Contamination is the enemy of a quality stainless weld. This brush is manufactured with .014-inch stainless steel wire specifically to prevent the introduction of free iron into your weld zone. This is critical for maintaining the corrosion resistance of 300-series stainless steels and aluminum alloys. The "left-hand twist" of the knots tightens the wire during rotation, preventing the filaments from unraveling prematurely and ensuring the brush maintains its aggressive cutting action throughout its life. This translates to fewer brush changes and more arc time.

Designed for use with high-speed die grinders, the Pferd 83284 is balanced to run smoothly at speeds up to 20,000 RPM. This high RPM capability allows for rapid cleaning action, essential for production welding environments. The protective coating on the cup is a welder-friendly feature, preventing accidental arc strikes or scratches on polished surfaces when working in confined geometries. Add this robust tool to your grinding arsenal to ensure your stainless projects meet the highest standards of cleanliness and finish.
