Not really. It is important for the collet bore and TTS shank to be clean and dry, and it helps to put a VERY thin coat of anti-sieze on the collet taper. But, at 25 ft-lbs, there is NO way a 1/4" tool will EVER pull-out, unless the collet, tool shank, spindle bore, or drawbar is significantly damaged.
