My current project is remodeling a 95yr old kitchen.

Issue: I'm Installing counter height electrical outlets (3) and I've already cut out the holes for the outlet boxes and I'm now running the Romex wire. On two of the outlets, it's not a straight path to the bottom sill plate. In the middle is a "not fire break but rather a diagonal support". I need to drill a hole thru this diagonal 2x4 for the wire, but my long drill bit wants to slip to the very lower corner. I want to drill in the center.

Hope that makes sense. I have access to under the house but the space below the wall sill is only about a foot, so a long drill bit from underneath is not an option. I was thinking of using a short drill bit with sever extensions until I reach the diagonal support.

I'm hoping that I don't have to open the wall, but I will if I have too. It's lath & plaster so not as simple as cutting out a section of drywall. But, if I have to cut out, it will be covered by cabinets in the long run.

Just checking with the brain trust here as many have more expertise than me.
