Value Collection S04186144 Cup Brush 3 in Steel Crimped

Product Description

The VALUE COLLECTION S04186144 is a crimped steel cup brush designed for aggressive surface preparation on metal, welds, and castings. The 3-inch diameter brush uses 0.012-inch steel wire in a crimped configuration, which provides medium-grade abrasion suited for rust removal, scale cleaning, paint stripping, and weld spatter cleanup. It is rated to a maximum of 12,500 RPM and mounts via a 5/8-11 threaded arbor, making it compatible with standard angle grinders and bench grinders. The brush ships individually and is used by fabricators, pipefitters, welders, and maintenance technicians working on steel surfaces.

This cup brush is suited for general industrial and maintenance applications where a powered wire brush is required to clean or prepare metal surfaces. Typical uses include weld joint preparation, corrosion removal on structural steel, and surface conditioning prior to coating or welding. The crimped wire fill offers flexibility and longer service life compared to knotted wire on moderately scaled or corroded surfaces. It is appropriate for both shop and field use where an angle grinder or compatible grinder with a 5/8-11 arbor is available.
