Aurora V. ★★★★★

The 29-tooth count was exactly what my mini mill needed to get the fine feed working smoothly again after the old gear cracked. Fits perfectly into the mechanism and feels solid during operation.

Steven ★★★★★

Replaced the stripped Z-axis feed on my mini mill and the 29-tooth mesh is spot-on, no slop or binding through the full travel. It’s machined cleanly enough that I didn’t have to file anything, which is rare for these small parts.

Brian ★★★★★

The 29-tooth worm gear dropped straight into my mini mill’s Z-axis feed without any fiddling—the tooth profile matches the original perfectly. Took about twenty minutes to swap out, and the fine feed now turns smoothly with no backlash.
