Value Collection 3107006320 Cup Brush Brass Crimped

Product Description

The VALUE COLLECTION 3107006320 is a crimped-wire cup brush designed for surface preparation, cleaning, and deburring on metal and other hard materials. The brush measures 2.75 inches in diameter with a 0.008-inch brass wire fill, making it well suited for light-to-medium cleaning tasks where a softer wire is needed to avoid scoring the base material. The 1/4-inch shank mounts directly into a standard drill chuck or die grinder collet. Maximum rated speed is 8,500 RPM. Machinists, fabricators, and maintenance technicians use this brush for weld prep, rust removal, flux cleanup, and general surface conditioning.

This cup brush is a practical fit for shop and field applications involving ferrous and non-ferrous metals. The brass wire construction resists sparking, which is relevant in environments where ignition hazards are a concern. The crimped wire configuration provides a degree of flex, reducing the chance of wire breakage during surface contact and delivering a more consistent finish compared to knotted styles. Typical applications include cleaning pipe fittings, conditioning weld joints, and removing oxidation from copper or aluminum surfaces.

Key Features

• 0.008-inch brass wire diameter provides controlled aggression without excessive material removal
• Crimped wire fill offers flexibility and reduced wire breakage under load
• 1/4-inch shank arbor fits standard drill chucks and die grinder collets
• 8,500 RPM maximum rated speed compatible with common handheld rotary tools
• Brass fill is non-sparking, suitable for use near flammable residues or in restricted environments

Compatibility

Designed for use with rotary tools, portable drills, and die grinders equipped with a 1/4-inch collet or chuck. Fits standard 1/4-inch shank tooling setups common in maintenance, fabrication, and trade applications.

Installation Notes

Installation is performed by a machinist, fabricator, or qualified maintenance technician. Secure the 1/4-inch shank fully into the tool collet or chuck and verify the locking mechanism is tight before operation. Always confirm the tool RPM rating meets or exceeds the brush maximum of 8,500 RPM before use, and never exceed that rated speed. Wear appropriate eye protection and gloves during operation, as wire bristles can shed under load.
