Value Collection S04185807 Cup Brush 4in Knotted Steel

Product Description

The VALUE COLLECTION S04185807 is a knotted steel cup brush designed for aggressive surface preparation on metal, welds, castings, and coated surfaces. The brush measures 4 inches in diameter with a 0.02-inch wire diameter and a single-row configuration. A threaded M16x2.00 arbor hole mounts the brush directly to angle grinders and compatible threaded spindle tools. Rated to 8,500 RPM maximum, this medium-grade brush delivers the wire tension and bite needed for paint removal, rust stripping, and weld spatter cleanup in fabrication and mechanical service environments. Licensed trades and maintenance professionals rely on this style of brush for pre-weld and pre-coat surface conditioning.

This cup brush is suited for use in metal fabrication shops, HVAC mechanical rooms, plumbing and pipe fitting work, and general industrial maintenance. The knotted wire construction handles heavy-duty stripping tasks where crimped brushes fall short. Single-row geometry concentrates wire contact on a tighter working surface, making it effective for cleaning weld seams, pipe ends, and localized corrosion spots. It is sold individually and is a practical consumable for service vans and shop tool stations.

Installation Notes

Always disconnect or de-energize the tool before mounting or removing the brush. Confirm the tool RPM rating meets or stays below the 8,500 RPM maximum marked on the brush before operation. Wear appropriate eye, face, and hand protection during use, as wire fragments can break free under load. Follow ANSI B11 and applicable shop safety standards when operating angle grinders with abrasive or wire accessories.
