TC-S2Dn-O

Looks like we are leaning to get a TC-S2Dn-O brother, with 16k rpm.

I was curious on some of the options. Looks like the big plus option is 6k. How necessary is this option? how much difference in milling would we expect?

The extended coolant with washdown. is the tank to small with out this?

How many have bought the chip conveyor with this machine? Did you see the need for it, or just stick to light duty milling?

Thanks,

Jim
