Wire Cup Brushes

Cup brushes present their fill face-on for cleaning broad surfaces on an angle grinder. Thread size, fill and knot or crimped are stated on every listing.

Choosing the right one

Cup brush or wheel brush?

A cup brush presents its fill face-on, which suits cleaning broad flat and irregular surfaces on an angle grinder. A wheel brush works on its edge and gets into corners, fillets and along weld lines.

Knot or crimped?

Knotted cup brushes are for heavy scale, slag and paint. Crimped cup brushes are softer and suit general cleaning and light finishing.

Will it fit my grinder?

Cup brushes are threaded rather than arbor-mounted. Check the thread on the grinder spindle — 5/8"-11 UNC is the common size on angle grinders — and match it. This is the detail most often ordered wrong.
