I'm sure somebody who does this for a living doesn't use 6 bits to get through this mesh. Can anybody give any solid advice? Need a 1/4' hole.

Mhonard, send me a PM with your phone number and i will give you a call, i have done a few dozen holes just like what you want to do, and I will be glad to discuss what works. NOTE: if your house is like mine (2013 Gardenia) there is a steel (actually stainless steel I think) channel with rebar that is filled with concrete, and then stucco is applied over that. The problem is with the stainless steel.
