عجلة رفرف مركبة 3 بوصة × 1 بوصة × 1/4 بوصة

I've been using this on an old steel gate latch, and the 1/4" arbor fits my die grinder perfectly. The aluminum oxide grit eats through surface rust fast without loading up. A solid little wheel for the money.

Took some rust off an old bench vise in a few minutes with this flap wheel, and it didn't leave deep scratches like a wire brush would. The 1/4-inch arbor holds firm in my drill, no wobbling at all.

Took off rust from an old metal gate in no time—the 1/4-inch shank held steady through the whole job. Even smoothed some rough edges on a piece of scrap wood afterward without switching tools.
