The Twist Knot Circular Wire Brush 115M x M14 is a threaded power-tool brush designed for aggressive surface preparation and cleaning on metalwork. Its 115 mm diameter head is formed from twisted knot wires that provide a concentrated, cutting action for rapid removal of rust, scale, paint and weld spatter; the M14 threaded arbor (M14 x 2.0, ISO metric thread) allows direct fitting to UK and European angle grinders and other compatible power tools.

This brush is manufactured with AISI 304 stainless steel wire (EN 1.4301) giving improved corrosion resistance where chemical or outdoor exposure is a factor. The central drive boss is supplied with an M14 female thread to match the standard ISO metric spindle, and the knot-style head retains its form under heavy contact for consistent material removal. The brush is supplied in the natural stainless finish; wire diameter and knot density are chosen to give an aggressive yet controllable cut rate for metal cleaning tasks.

Typical applications include removal of rust and millscale, preparation of weld seams before inspection or painting, cleaning of castings and forgings, deburring of heavy fabrication components and surface preparation prior to coating. Industries that commonly use this type of brush are metal fabrication, shipbuilding and marine maintenance, chemical plant turnaround teams, rail and infrastructure maintenance, and automotive restoration.

Key benefits of the twist knot design are concentrated cutting action for fast material removal, longevity under intermittent heavy use due to the knotted wire construction and, when made in stainless wire, improved resistance to corrosion and contamination of the workpiece. The M14 thread ensures broad compatibility with European and UK grinders; the robust wire grade maintains edge contact without excessive feathering, reducing time spent on rework.
