I use the Rock Chuck. Where can I find the 1/4" diameter bits only (no shank pressed on) for my machine? Also, I will need the collars with set screw for the bits.

Also, I have seen there is a 1/32" ball-nose bit. Would this make a noticeable difference in carving quality? My firmware is 1.188.00016, so it may be that it would not be compatible.
