Value Collection S04186250 Cup Brush 4in Steel Crimped

Product Description

The VALUE COLLECTION S04186250 is a crimped-wire cup brush designed for surface preparation, weld cleaning, rust removal, and scale removal on metal workpieces. Built with a coarse-grade steel fill, it mounts to angle grinders and other threaded-arbor tools via a standard 5/8-11 threaded arbor hole. The brush measures 4 inches in diameter with a wire diameter of 0.015 inches and a trim length of approximately 25 millimeters. Maximum rated speed is 8,500 RPM. Crimped wire construction provides a more flexible, moderate-aggression cut compared to knotted wire, making it well suited to contoured or irregular surfaces where a rigid brush would lose contact.

This cup brush is used in metal fabrication shops, welding operations, pipeline maintenance, and general industrial settings. Typical applications include pre-weld joint cleaning, post-weld slag and spatter removal, and surface prep before coating or priming. It is appropriate for use on steel, cast iron, and other ferrous substrates. The coarse grade and 4-inch diameter make it a practical choice for medium to large work areas where a flat or flap disc would be inefficient.

Key Features

• 4-inch brush diameter for broad surface contact
• 0.015-inch steel wire diameter with crimped construction for flexible, moderate-aggression action
• Coarse grade fill for aggressive rust, scale, and weld spatter removal
• 5/8-11 threaded arbor hole fits standard angle grinder spindles
• 8,500 RPM maximum rated speed
• 25-millimeter trim length provides consistent wire projection

Compatibility

Designed for use with angle grinders and die grinders fitted with a 5/8-11 threaded spindle. Confirm that the tool's rated free speed does not exceed 8,500 RPM before mounting.

Installation Notes

Installation should be performed by a qualified operator following tool and abrasive safety guidelines. Power down and disconnect the tool from its power source before mounting or removing the brush. Thread the brush securely onto the spindle and verify it is fully seated before operation. Always confirm the tool's rated no-load RPM does not exceed the brush's 8,500 RPM maximum, and use appropriate eye and face protection during operation per ANSI B11 and OSHA abrasive tool standards.
