Perfect for my CNC spindle
Works exactly as described. The brass is high quality and the fit on the shaft is precise with no wobble.

Nice finish
Slightly heavier than expected but the polished finish looks great and prevents corrosion.

Good value
Solid build but screws were a bit tight out of the box. Once installed, it holds torque well.
