Hi, im about to mill some copper blocks, heres some 3d designs and figures
the block Is 2”x2”x.75” the channels are .65” deep and I will be using a 1/8” carbide tip router bit, but im unsure of what coolant to use, can I use water, and how would I apply the coolant, I read its hell to mill copper, but im doing this to cool my computer, this is my first time, thx a lot!
