Value Collection PB33400 Cup Brush 1-3/4 in Stainless Steel

Product Description

The VALUE COLLECTION PB33400 is a crimped-wire cup brush designed for use with rotary tools, die grinders, and electric drills. It features a 1/4-inch shank arbor for direct chuck mounting and a 1-3/4-inch brush diameter with 0.0118-inch diameter stainless steel fill wire. The crimped wire construction flexes under load to maintain consistent contact with irregular or contoured surfaces. Rated to 13,000 RPM, this brush is suited for weld spatter removal, surface preparation, rust and scale removal, and light deburring on metal components. It is a standard tool in HVAC sheet metal work, plumbing rough-in prep, and general mechanical fabrication.

This cup brush fits common applications in trade and light industrial environments where a compact, shank-mounted abrasive tool is needed. Typical uses include cleaning pipe ends before soldering or brazing, removing oxidation from metal fittings, and surface conditioning on welds prior to inspection. The stainless steel wire fill resists contamination of workpieces where carbon steel wire is not acceptable, such as on stainless or aluminum substrates.

Installation Notes

Always verify that the tool's rated RPM meets or exceeds the brush's 13,000 RPM maximum before mounting. Wear appropriate eye protection and a face shield when operating any wire brush. Inspect the brush before each use and remove from service if wires are broken, frayed, or unevenly worn. Follow ANSI B11 or applicable shop safety standards for abrasive and wire brush use.
