Mini mill is probably less likely to spins drills in a keyless chuck. I have gone back and forth with keyless chucks vs. keyed, bottom line is some keyed chucks are better than others. I have used the higher end Precision Mathews integral r8 chuck and it works very well, also had a glacern, Vertex, LLambrich and Jacobs keyed chuck. My first choice is the LLambrich JK-130 or JK-160 in a keyless chuck, seems to work smoothly, always hold the drills securely and never had a problem with it over tightening. It also come with a wrench for tightening or loosening as needed, TIR is around 0.001". Vertex is als nice about the same as the PM keyless chuck. Also a few other brands that have nickle plated precision keyless chucks like SHar's which are very good.
If you are holding endmills, then there are ER-32 collet systems, the chuck has an integral R8 arbor, you need a decent set of collets. I do not use them for drilling.
