Norton 662528-39039 Twist Knot Wire Wheel Brush 4 in

Product Description

The NORTON 662528-39039 is a stringer bead twist knot wire wheel brush designed for aggressive surface preparation and weld cleaning on metal workpieces. Constructed from stainless steel wire at 0.02 inches in diameter, the twist knot configuration delivers concentrated cleaning action with consistent cut rate throughout the life of the brush. The 4-inch brush diameter fits standard angle grinders and bench grinders equipped with a 5/8 inch-11 arbor. This brush is used by welders, fabricators, and general trade professionals who need reliable weld bead cleaning, rust removal, and surface conditioning on ferrous and non-ferrous metals.

This brush is suited for weld shop, fabrication, and field service applications where stringer bead cleaning and heavy-duty surface preparation are required. The stainless steel wire construction prevents cross-contamination on stainless steel workpieces, making it appropriate for food-grade fabrication environments and other applications where carbon steel contamination must be avoided. Sold in a box of 10 brushes, this format supports shop stocking and crew-level supply needs.
