Value Collection S04186292 Cup Brush 4 in Steel

Product Description

The VALUE COLLECTION S04186292 is a crimped-wire cup brush designed for surface preparation, rust removal, weld cleanup, and paint or coating removal on metal surfaces. Built with fine-grade steel wire at 0.008 inches in diameter, the brush delivers consistent finishing action without overly aggressive stock removal. The 4-inch brush diameter provides solid contact area for angle grinder work, and the threaded 5/8-11 arbor hole fits directly onto standard grinder spindles. Rated to 8,500 RPM maximum, this brush suits typical variable-speed and fixed-speed angle grinders used in fabrication, maintenance, and field service work.

This cup brush is suited for use in metal fabrication shops, pipefitting, structural steel work, and general maintenance applications. It performs well on flat and slightly contoured surfaces where wire brushing with an angle grinder is the preferred method. The crimped wire construction provides a medium-to-fine scratch pattern, making it appropriate for prep work before welding, coating, or inspection. A trim length of 25 millimeters supports consistent contact pressure throughout the brush life.

Installation Notes

Installation should be performed by a qualified tradesperson following the grinder and brush manufacturer safety guidelines. Ensure the grinder is fully powered off and unplugged before mounting or removing the brush. Thread the brush firmly onto the 5/8-11 spindle by hand, then verify it is secure before operation. Always operate at or below the rated 8,500 RPM maximum and wear appropriate PPE including eye protection and gloves when using wire cup brushes.
