كوب معقود من الفولاذ المقاوم للصدأ 4 بوصة × 5/8-11 (MERCER) .020

Tackled a heavy rust patch on an old trailer hitch with this cup brush last weekend—the .020 stainless steel knots chewed through it faster than I expected. Fit my angle grinder perfectly with the 5/8-11 arbor.

The knotted wires on this cup brush are thick and stiff, tearing through old paint and rust on my steel gate in minutes. It held up well to heavy pressure without any wires flying loose. Exactly the aggressive cleaning power I needed for tough jobs.

Switched from a different brand's brush to this one, and the .020 wire feels noticeably sturdier—it ripped through caked-on rust on an old trailer hitch in under two minutes without losing its shape.
