Value Collection S04185450 Cup Brush 2-3/8 in Knotted Steel

Product Description

The VALUE COLLECTION S04185450 is a knotted steel cup brush designed for aggressive surface preparation on metal, welds, and coatings. The 2-3/8 inch diameter brush head features a single row of medium-grade knotted steel wire at 0.012 inches wire diameter, delivering consistent cutting action on rust, mill scale, paint, and weld spatter. The 1/4 inch shank mounts directly to angle grinders, die grinders, and drill presses. Rated to 6,000 RPM maximum, this brush suits heavy-duty cleaning and finishing tasks in fabrication, HVAC installation, plumbing rough-in, and general mechanical work.

This cup brush is suited for use on structural steel, pipe ends, weld joints, and sheet metal surfaces where wire brushing is required before coating, welding, or inspection. The knotted wire configuration is the correct choice for harder base materials and stubborn surface contamination. The 1/4 inch shank arbor type provides compatibility with common rotary tool chucks and collets used in trade and shop environments.
