Can a flex bit drill through 4 joints which are 1 foot apart?

For my light project, I want to cut two 6-inch recess light holes which are ~50 inches apart. My ceiling has joints which are 12 inches apart. So I will need to drill through 4 joints to connect two lights. Could a 1/2-in diameter 72-inch flex bit like this be able to drill through 4 joints?

Yes it is possible and the drill is capable of drilling through multiple studs/joists. You will also need a drill guide tool. Some drills come packaged with the tool so shop around and see what is a better deal. With that tool you can angle the drill up into the hole and bend the shaft to send it horizontally into the cavity. If possible I would get some practice before working in your ceiling so you get a feel for positioning the drill. If your horizontal is off you can end up wandering off.

I could not clearly see in the drill you linked if there was a hole on the end of the drill bit. You definetely want a hole. After drilling the hole allows you to attach the end of your wire so as you pull out the drill bit you pull the new wire through the holes you just drilled. There are kit's like this that have everything you need.

 

It will not be easy to control the end of the drill when it gets to the last joist. Drilling thru one or two joists is no problem. As the distance increases.... so does the angle of the drill. Also..... remember you're drilling blind. It's hard knowing if anything is in the bays.
