All chucks are secondary, Dewalt does not make them. It happens, I'd just have it swapped out at the service center, or exchange it.
Hey thanks for the reply. I went by a service center here today and you would know it worked fine for him. I did notice that after I tighten the bit I can turn the chuck till it clicks. this seemed to work at the time. Service guy said it is a lock. Guess i'll try this and see if it works out. I ordered this kit from amazon.com. so might be a big mistake to try and return it for another. But thanks again.
