Lily ★★★★★

The knotted .020 wire chewed through the baked-on gunk in my die grinder’s corners without shedding bristles, and the 1/4" shank held tight at full throttle. It’s a bit aggressive for soft metals, but for 20,000 RPM work on steel, this little brush is a beast.

Leo ★★★★★

I needed a brush to tackle rust in narrow slots, and this knotted wire end brush fit perfectly in my die grinder. The 1/4-inch shank held tight even at high speeds, and the 0.020 wire really dug into the surface without flying apart. Does exactly what it’s supposed to for the price.

Olivia L. ★★★★★

I used this to clean up some tight engine parts, and the 20,000 RPM rating means it works fast without bogging down. The knotted wire really digs into grime, though I wish the brush were a bit larger for bigger jobs. Still, it's a solid performer for the price.
