齒輪，R8 主軸 1 號，迷你銑床，金屬

Installed this on my mini mill spindle and the 29 teeth mesh exactly as needed. It's solid steel and handles the driven shaft load without any wobble.

The 29 teeth lined up perfectly with the driven shaft on my R8 spindle, so the whole swap took under an hour. It’s solid steel, so it feels like it’ll outlast the rest of the mill, and the machining on the tooth edges is clean with no burrs.

Installed this 29-tooth gear on my mini mill's spindle and it meshed perfectly with the drive shaft. The steel feels solid and the teeth are cut cleanly, no burrs or wobble during test runs. Zero issues so far.
