Customer Reviews (4.6 / 5 · 5 reviews)

Nicholas ★★★★★

Installed these last weekend and was impressed how smoothly they meshed with the existing gear train right out of the box. My mini lathe runs noticeably quieter and I no longer worry about plastic teeth stripping during heavier cuts.

Timothy ★★★★★

Took about an hour to swap out the old gears, and the steel ones mesh so much smoother than the plastic ever did. The lathe runs quieter now, and I don't worry about stripping a tooth mid-project anymore.

Leo ★★★★★

The plastic gears on my lathe finally gave out, so I swapped in this steel set. The machining is precise and they fit without any extra fiddling, which was a relief. Definitely feels like the machine will last a lot longer now.
