We are trying to optimize production by keeping both turrets active during the entire production process. The only way to do this on some of the cam followers we produce is to have the thru hole drilled on the part on the main spindle while roughing/finishing with the other turret. Usually we split the turrets up to work on the main and sub spindle separately, but all the operations available on the sub spindle are taken care of.

I got some carbide drills that can handle the rpm's used while roughing/finishing which seemed to be the only issue besides making sure both turrets have adequate room to work without crashing into each other, but I just wanted to get a second opinion on this. Will one operation affect the other?
