主軸鎖定

I appreciate how precisely this spindle lock aligns with the 4700's threads—no wobble or play. It made my first tool change much faster and less stressful.

I've swapped out tool bits twice since getting this and the spindle hasn't budged once, which makes the whole process feel way safer. Fits the 4700 mill snugly, so no wobble or guesswork when I'm tightening things down.

Honestly, I was a little skeptical about another locking mechanism, but this one does exactly what it says. It holds the spindle rock-solid during a tool change, and the fit on my 4700 mill was perfect.
