Value Collection 3103806330 Cup Brush 1-3/4 in Brass

Product Description

The VALUE COLLECTION 3103806330 is a crimped-wire cup brush designed for surface preparation, cleaning, and deburring tasks across metal fabrication, plumbing, HVAC, and general mechanical work. The brush measures 1.75 inches in diameter and uses 0.012-inch brass wire in a crimped fill pattern, which delivers consistent scrubbing action while reducing wire breakage during extended use. The 0.25-inch shank mounts directly into a standard drill or die grinder. A maximum rated speed of 13,000 RPM makes it compatible with most handheld power tools used in trade and shop environments.

This cup brush is suited for light to medium surface work including removing oxidation, scale, flux residue, and light corrosion from copper, brass, and soft metal fittings. Plumbers and HVAC technicians commonly use crimped brass cup brushes to prep pipe ends and fittings before soldering or brazing. The soft brass wire minimizes surface gouging on non-ferrous materials, making it appropriate where steel wire would cause contamination or damage.

Key Features

• 1.75-inch brush diameter for targeted surface coverage in tight areas
• 0.012-inch brass wire fill resists contamination on copper and non-ferrous metals
• Crimped wire construction provides flexible, consistent contact across irregular surfaces
• 0.25-inch shank fits standard drill chucks and die grinder collets
• 9/16-inch trim length delivers controlled reach and stiffness
• Rated to 13,000 RPM for compatibility with common handheld rotary tools

Compatibility

Designed for use with handheld power drills and die grinders accepting a 0.25-inch shank. Suitable for surface preparation on copper, brass, and other non-ferrous metals in plumbing, HVAC, and light fabrication applications.

Installation Notes

Install the shank securely into the drill chuck or collet before operation and confirm the tool RPM rating does not exceed 13,000 RPM. Always wear ANSI-rated eye protection and gloves when operating wire brushes, as wire fragments can become projectiles. Inspect the brush before each use and discard if wires are bent, missing, or show signs of fatigue. Do not exceed the rated maximum RPM under any operating condition.
