Well I can't measure run out on the actual end mill, so I am using various parts of the toolholder/spindle housing as proxies....
Is this normal? Or does the tool holder need slinging

Measure the runout of the taper in the spindle to establish if it is running true. You should have a total movement of less than 0.01mm (according to my old books)
Then install a tool holder and measure the TAPER of the collet . NOT the thread or the locking nut.
Then install a ER collet with a reference bar. A ground piece of metal like a edgefinder is fine and measure that.
With good stuff you should not have a cumulative runout of more than 0.05mm
Thanks - that is really helpful
