I'd like to run 1/4, 1/8 and 3/8" shank bits in the CarveTight. Can I use the two-piece/split collet for the Rock Chuck with these diameters of bit, and hold securely in the CarveTight?

Can the Rock Chuck collets hold solid carbide tooling, or are they only for high speed steel like the CarveTight?

Thanks!
