I have to say i am so glad i upgraded to the CT. before i would all ways worry if my carve was going to turn out right, or i would only be able to get a few carvings done before the bit screwed up. i stopped carving because of all the problems i had with the old QC chuck.
now i feel confident that things are not going to get screwed up. i have already carved more in the 2 months that i have had the CT than in the two years i have had the CW.
