The key is this dinky small thing, and doesn't do squat to keep the tool from rotating. If you generate enough torque on the collet, so much so that it spins, that pin is going to shear straight away and dig in to the collet. Trying to get the collet out after that is no fun whatsoever.
Just take the darn thing out, and save yourself time and effort putting tools in the machine as well as recovering from crashes. |
