LG Brush manufactures cup brushes in our Shanghai plant — ISO 9001 certified, 20+ years in industrial brush tooling. Below you'll find every cup brush we build, with custom sizes, grits and shanks available on request.

What Are Cup Brushes Used For?

Cup brushes are made for angle grinders and drills: knotted wire for heavy weld and scale removal, crimped wire for lighter cleaning, and abrasive filament for aluminum parts where the base surface must stay undamaged.
