Robert H. ★★★★★ Oct 22, 2026

Finally got my SC4 lathe to cut metric threads without fuss after swapping in this 127-tooth gear set. The machining on the teeth is visibly clean, and they meshed right in with no filing needed.

George ★★★★★ Oct 21, 2026

My SC4 lathe was limited on thread options until I installed this gear set. The metal construction feels solid and the extra gears fit perfectly, giving me much more flexibility for custom projects.

Lily ★★★★★ Oct 20, 2026

These three gears filled the gap my lathe was missing right out of the box, and the machining on the teeth is clean with no burrs. I swapped them in for a metric thread job and the engagement felt solid, no chatter at all.
