Graphite shaft extraction

Metal is a very good conductor of heat and graphite is a very poor conductor. The longer the time you take, the more the graphite shaft itself will heat up and the higher the temp you can get in the shaft and the higher the risk for doing damage to the shaft. Also means the metal will loose heat a LOT faster than the graphite.
