Value Collection S04186193 Cup Brush 3-3/16 in Steel

Product Description

The VALUE COLLECTION S04186193 is a crimped-wire cup brush designed for aggressive surface preparation on metal, welds, and castings. The brush measures 3-3/16 inches in diameter and uses 0.015-inch-diameter steel wire in a crimped configuration, which provides consistent pressure and helps the brush conform to irregular surfaces. It is rated for a maximum of 8,500 RPM and mounts via a standard 5/8-11 threaded arbor, making it compatible with most angle grinders used in fabrication, maintenance, and industrial trades. The coarse grade wire delivers fast material removal for rust, scale, and weld spatter cleanup.

This cup brush is suited for use on ferrous metals in light fabrication shops, maintenance and repair operations, and general industrial applications. Typical tasks include weld bead cleaning, rust and mill scale removal, and surface conditioning before coating or painting. The crimped fill pattern is well suited for flat and slightly contoured surfaces where consistent contact pressure across the full brush face is needed. Installation requires an angle grinder with a 5/8-11 spindle thread.

Installation Notes

Installation and operation of wire cup brushes should be performed by qualified personnel familiar with angle grinder safety. Always disconnect or de-energize the grinder before mounting or removing the brush. Thread the brush onto the 5/8-11 spindle and hand-tighten securely before operation. Do not exceed the rated 8,500 RPM maximum speed, and ensure the grinder is rated at or below that speed before use. Wear appropriate PPE including eye and face protection, as wire bristles can become projectiles during use.
