Here's a weird question.

Got these knurls out of a cabinet

I began to wonder if, perhaps, I can use them on my CNC mill, in order
to make knurled surfaces. Just put one (on a toolholder) in a spindle,
put the spindle on brake, and knurl the surface? Anyone tried this?

Not I. Not sure that the spindle can apply sufficient force.

Just hold them to swap into the Turret T knurlers discussed in
another thread. Knurls wear out, and you will need matched pairs for
the knurler.

Enjoy,

I ran a job (a tool) for one of my customers that required a straight knurl
in a groove. Using a single coarse roller, I made a holder that was held
in a 3/4" collet and knurled the part (tool steel). Worked fine, but
required several passes. Did it on a Bridgeport mill, in fact.

I expect you'd have similar success with a diamond tool, although you won't
be able to achieve the diamond pattern on a blind piece unless you do it
with single rollers, one at a time.

Just had this thought:

You can make a very similar surface quickly with a scribe tool on a
CNC mill. Just program your pattern. I wouldn't risk harm to your Z
ball screw.

I've never discounted the possibility of bearing damage (brinelling) on the
static spindle, either.
