If the toolholder selected has a gage length value in the database and you can get the the tool assembly's overall length offset from the operator, you can skip measuring the endmill stickout. In this example the toolholder had a 8" gage length and it shows in the Total Gage Length field.
The tool length offset is 10.5" so we enter that in the same field.
This will automatically change the Stickout in the Tool Details file to 2.5".
