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.

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.

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.
