Excelent Quality
I use this to connect a NEMA-8 stepper motor with 4mm shaft to reduce the output 60:1. It works very well and has smooth motion. The parts are well machined and can't observe any eccentricity in either part.

Solid Quality Brass Gear Shaft for Precise Projects
This CNBTR brass gear shaft with a 4mm bore and 60 teeth works well for my small mechanical builds. The brass feels sturdy and the gear teeth are well-machined for smooth operation. It fits perfectly in my drive gear box setup. My only small note is that it requires careful handling due to the precision parts, but overall itโs a reliable component for hobby or DIY projects.

Definitely useful
Needed for a project where my motor needed a small lightweight gear. Good for use with a motor for a worm gear
