Value Collection S04185609 Cup Brush 2-5/8 in Knotted Steel

Product Description

The VALUE COLLECTION S04185609 is a knotted steel cup brush designed for aggressive surface preparation on metal, welds, and castings. The knotted wire configuration delivers more cutting action than crimped brushes, making it well suited for removing heavy rust, mill scale, weld spatter, and coatings. Wire diameter measures 0.0137 inches, providing fine-grade cutting action with good durability. The brush mounts via a 5/8-11 threaded arbor hole and is rated to a maximum of 12,500 RPM. It is intended for use with angle grinders and is a standard tool in fabrication shops, pipefitting, and structural steel work.

This cup brush is used in applications where surface cleanliness and profile are critical before painting, coating, or welding. The single-row knotted construction concentrates wire contact on the work surface for consistent scratch pattern and material removal. Typical install or use scenarios include weld prep on structural members, cleaning corroded pipe flanges, and stripping heavy oxidation from carbon steel. It is a common consumable for ironworkers, pipefitters, welders, and maintenance technicians working on ferrous substrates.

Installation Notes

Always power down and disconnect the grinder from its power source before mounting or removing the brush.

Wear appropriate PPE including a face shield, gloves, and hearing protection when operating wire cup brushes. Follow ANSI B7.1 and tool manufacturer guidelines for wheel mounting and guarding.
