4" Twist Knot Wire Cup Brush M14x2

This 4" (100mm) twist knot wire cup brush is your go-to accessory for aggressive surface cleaning and metal preparation. Unlike standard crimped brushes, the tightly twisted knot wires stay locked together under pressure, giving you a stronger, more concentrated cutting action that powers through rust, scale, old paint, and weld splatter without shredding apart.

Fitted onto your angle grinder via the M14x2 arbor, the cup shape directs all that abrasive power straight into the surface, making it especially effective on flat areas, corners, and welded joints where a flat wire wheel can't quite reach. Rated to a maximum of 8500rpm, it's built to handle sustained use on tough industrial and workshop jobs alike.

If you're restoring old metalwork, prepping steel before painting or coating, or cleaning up after welding, this cup brush cuts your prep time down significantly compared to hand sanding or scraping.

Where it works best:
Rust and corrosion removal from steel and iron surfaces, paint and coating stripping before refinishing, weld slag and spatter cleanup, general metal surface preparation in workshops, garages, and fabrication shops.
