Customer Reviews (4.8 / 5 · 5 reviews)

Zoe ★★★★★

Finally found a drop-in replacement for that worn bench lathe gear, and this one meshes perfectly with the existing worm and spindle. The 25 teeth are cut cleanly, no rough edges to file down before install.

Lucy ★★★★★

The 25-tooth count matches the SC4-316 diagram exactly, so no fiddling with shims or re-drilling. Threaded on smoothly and the lathe runs quieter than with the old worn gear.

Zoe X. ★★★★★

The tooth profile matches the original SC4 part exactly, which made swapping it in a quick job. My lathe is running smoother now with no binding or backlash.
