2-3/4" x 5/8"-11 Knotted Cup Brush for Carbon Steel are abrasive tools used for cleaning rust and removing paint. They are also used to clean surfaces and to create a better conductive area for attaching electrical connections. The knotted wire style is suited for medium to heavy duty jobs. This cup brush has 5/8"-11 threads for easy spin-on spin-off action. The carbon steel crimped wire cup brush is designed for cleaning and deburring rust, scale and dirt, edge blending, roughening for adhesion and weld prep.

More resistant to oxidation, stainless steel brushes are ideal for use with aluminum, stainless steel and other non-ferrous alloys.

The knotted cup brush is designed for rigorous workpieces. These knotted wire cup brushes are ideal for metal surface preparation, cleaning, removal of weld scale and rust. This cup brush provides flexibility for light removal of rust & paint & general cleaning.

Customer Reviews (4.8 / 5 · 5 reviews)

Nicholas Q. ★★★★★

Took off a thick layer of surface rust from an old steel beam in one pass, and the knotted wires didn’t shed a single bristle. The 2-3/4" cup size covers a lot of ground, so the job went way faster than I expected.

Elizabeth G. ★★★★★

The knotted wires really bite into carbon steel—I stripped a patch of heavy rust down to bare metal in a few passes without the brush clogging up. The 2-3/4" cup size feels solid and balanced in a standard grinder, and the stainless bristles haven't shed a single strand yet.

Alexander Y. ★★★★★

Took a wire wheel to a rusty steel gate and this thing ripped through the scale in minutes without clogging. The 2-3/4" cup size is perfect for covering flat surfaces fast, and the 5/8"-11 thread fit my grinder with zero wobble.
