Value Collection S04186102 Cup Brush 3in Steel Crimped

Product Description

The VALUE COLLECTION S04186102 is a 3-inch diameter crimped steel cup brush designed for aggressive surface preparation on metal, weld seams, and castings. The crimped fill wire at 0.015 inches diameter provides flexible, coarse-grade abrasion suited for rust removal, scale stripping, and paint removal. Rated to 12,500 RPM, this brush mounts via a threaded 5/8-11 arbor hole and is intended for use on angle grinders and bench grinders. It is a standard workhorse tool for maintenance techs, fabricators, and industrial service professionals who need consistent abrasive performance on a threaded spindle.

This cup brush is appropriate for heavy-duty surface prep tasks in manufacturing, fabrication, and maintenance environments. Typical applications include cleaning weld joints prior to inspection, removing mill scale from structural steel, and stripping oxidation from pipe ends before fitting. The coarse grade and crimped wire construction make it well suited for contoured and irregular surfaces where a rigid wire would chatter or skip. The threaded arbor mount allows quick swap-on compatible grinder spindles without additional hardware.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with abrasive tool safety. Disconnect and lock out power to the grinder before mounting or removing the brush. Thread the 5/8-11 arbor onto the spindle securely and verify the brush is fully seated before applying power. Always wear appropriate eye protection and face shield when operating cup brushes at speed.
