Spindle, 3MT, SX3 Small Mill CLEARANCE

The 3 Morse taper fit perfectly into my SX3 mill without any adjustments needed. I was pleasantly surprised by the precision machining for a clearance item.

Bolt-on replacement was dead straight, no runout issues on the 3MT taper, and it seated perfectly in the SX3’s drawbar. Just a heads-up it’s clearance stock, so check the finish for light storage marks, but mine cleaned up fine and runs true.

The 3MT taper is machined cleanly and the spindle runs true with no noticeable vibration at higher speeds. Swapping out the old one took about an hour, and it’s been solid through a few dozen cuts since.
