Pferd 79183109 End Brush 1/4 in Knotted Steel Wire 20000 Rpm

Product Description

The PFERD 79183109 is a knotted wire end brush designed for surface conditioning, deburring, and cleaning in confined areas. The brush features a single twisted wire knot construction in steel, with a working diameter of 0.25 inches and a wire diameter in the 0.0101 to 0.0200 inch range. Rated to a maximum of 20,000 RPM, it is built for use with die grinders and rotary power tools. A shank is included for direct chuck mounting. Licensed tradespeople and maintenance professionals use this brush for accessing inside corners, edges, and tight workspaces where flat or cup brushes cannot reach.

This end brush is suited for use on cast iron, cast steel, and steel workpieces in both industrial maintenance and fabrication settings. The knotted wire configuration delivers aggressive action on scale, rust, weld spatter, and burrs in areas that standard brushes cannot access. It is a single-unit package intended for professional use in shop, field, or plant maintenance applications where a compact, high-speed rotary brush is required.
