Matt,

can you run us through your process a bit more?

What spindle taper do you have on the machine? R8 MT-3, ISO?

Are you using a single collet chuck that you torque-untorque each time and replace endmills or drills with the haimer?

If you can spare it, se aside one collet chuck and use it only for the haimer. That way it is clean and will be as repeatable as possible (not trying to teach you anything you don't already know)

Was helping a lad out that had bought a 20mm LED/Beeping type edge finder by Vertex. He had it in a ER40 collet chuck and was also seeing massive runouts due to the length of the tool, basically the taper of the collet and that of the chuck were out and could be tweaked by hand. Once the tool was tweaked, it was fine...until he rammed it into the side of a vice
