Run-out tolerance · ISO 1101
Total run-out
Limits the variation over the whole surface when the part turns about the datum axis.
In the shop
Same causes as circular runout, accumulated along the length, so taper and bow count too. Use steady support on long parts and a light finishing cut.
General shop guidance in our own words. The drawing and the standard it cites decide; verify on a sample part.

Ask about your drawing
Tell the advisor the feature, the tolerance on the drawing and the material. It answers with machining choices, brand-neutral.
