It would be recommended to have a drill press for this. Carbide bits are very brittle (but very hard). If you don't keep the alignment of your bit straight throughout the process of drilling your hole, you may end up with a broken bit.
Besides the fact that carbide bits are expensive, if broken pieces of the bit gets wedged into the hole that you are drilling, you may not be able to get the lodged piece out of your tang.
Drilling with carbide should be done without cooling fluids. You are basically drilling the hole with friction, thus the need for high rpm.
Good luck.
