Chloe U. ★★★★★

Swapped out the factory gear on my mini lathe and this plastic one is noticeably lighter, which makes a difference during longer threading jobs. It clicked right into place without any wobble, and the 40 teeth have held up fine over several sessions.

Joseph ★★★★★

Exactly 40 teeth meshed perfectly with my lathe's existing gears right out of the package, and the plastic is surprisingly rigid where it counts. For a lightweight replacement part, it spins smoothly without any wobble.

Brian ★★★★★

I was a bit skeptical about a plastic gear, but the 40 teeth matched my mini lathe's threading setup perfectly and it's holding up well. The lightweight material actually makes swapping change gears faster since it's easier to handle than metal.
