Pferd 79182384 Knotted Wheel Brush 4 in Carbon Steel

Product Description

The PFERD 79182384 is a knotted carbon steel wheel brush designed for aggressive surface preparation and weld cleaning on angle grinders. With a 4-inch outside diameter and a 5/8-inch face width, it delivers concentrated wire contact across the work surface. The standard twist knot construction keeps wire ends tightly bundled, which focuses abrasive force and helps the brush maintain its shape under heavy use. Rated to 20000 RPM, it is compatible with the higher speeds common on 4-inch angle grinders. A threaded 5/8-11 arbor hole mounts directly to standard angle grinder spindles without an adapter. Licensed trade professionals in fabrication, maintenance, and industrial service routinely rely on this brush type for rust removal, paint stripping, and pre-weld surface conditioning.

This wheel brush is suited for use on ferrous metals in both residential and commercial applications. Typical tasks include cleaning weld seams, removing mill scale, stripping coatings, and deburring steel surfaces. The threaded mount and 20000 RPM rating make it a direct fit for most 4-inch angle grinders used in the field. No shank is included, so the tool mounts via the threaded arbor hole directly onto the grinder spindle. Wire filament diameter falls in the 0.0200 to 0.0299-inch range, providing an aggressive cut rate appropriate for heavy-duty surface prep work.

Installation Notes

Installation should be performed by a qualified technician familiar with angle grinder tooling and applicable ANSI and OSHA safety standards for abrasive wheel accessories. Always disconnect power and confirm the grinder is fully stopped before mounting or removing the brush. Thread the brush firmly onto the 5/8-11 spindle and confirm it is secure before operation. Always verify the tool RPM does not exceed the 20000 RPM rating of the brush, and wear appropriate PPE including eye and face protection when operating.
