Miles ★★★★★ Oct 19, 2026

Replaced the worn-out driven shaft gear on my mini mill and the 21-tooth count lined up without any fuss. The smaller size of this spindle gear made installation straightforward, and the machine runs quieter than it has in months.

Sofia ★★★★★ Oct 18, 2026

The 21 teeth matched perfectly with the existing gear in my mill's transmission, so no modification was needed. It feels solid and machined well, definitely a precise replacement part.

Owen ★★★★★ Oct 13, 2026

Wasn't sure the 21-tooth count would match my old gear but it lined up perfectly and meshes smooth through both speeds. Spindle runs quieter now than it did before the swap.
