Weiler 90325 End Brush 1-1/8 in Stainless Steel Knotted Wire

Product Description

The WEILER 90325 is a knotted-wire end brush designed for aggressive surface preparation, deburring, and cleaning on metal workpieces. Built with stainless steel wire fill, it delivers effective cleaning action without carbon contamination on stainless steel base materials or other corrosion-sensitive surfaces. The brush measures 1-1/8 inches in diameter and mounts via a 6 mm shank, making it compatible with die grinders and other rotary tools. Rated to a maximum of 22,000 RPM, it suits high-speed finishing work. Licensed trades and fabrication shops rely on this type of end brush for weld prep, scale removal, and surface cleaning in tight or recessed areas inaccessible to larger wheel brushes.

This end brush is suited for use in light fabrication, maintenance, and repair applications where stainless steel wire is required to prevent cross-contamination. The knotted-wire construction provides more aggressive cutting action compared to crimped-wire configurations. Common applications include tube interiors, pipe ends, bore surfaces, and weld joint cleaning on stainless steel or other alloy components. It is a single-pack unit, making it straightforward to stock as a consumable or add individually to a job kit.
