1" 직경 x 1/4" 생크 매듭 와이어 엔드 브러시 0.020 최대 20,000RPM (수입)

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.

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.

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.
