I will have to think through that. The chuck works fine with with shorter 1/2" bits, even a fairly hefty V-bit and it works fine with a 1/4" collet and end mills with 1" cutting depth. If it was just the longer 1/2" bits, I would expect to have at least a little bit of problem with with the standard router collet but it runs smoothly with the standard collet.
