Customer Reviews (4.8 / 5 · 5 reviews)

Kevin X. ★★★★★

Threaded the metric pitch I needed on my mini lathe perfectly on the first try — the 21 teeth make a real difference. The metal gear feels sturdy and seated without any wobble, though I did have to check my existing spacing first.

Matthew M. ★★★★★

The metal construction feels solid and the teeth mesh perfectly with my lathe's existing gears. I've already cut a few metric threads and the accuracy is noticeably better than before.

Christopher C. ★★★★★

Finally got my mini lathe cutting metric threads accurately; the metal gear feels solid and the 21 teeth line up perfectly with my lead screw. No more guessing or buying expensive thread dies.
