Drill joints diagonally for recessed lights?

My ceiling has joints 1-foot apart and I need to drill a hole to get a wire from light A to B.

Could I use a flex drill bit to drill diagonally from light A to B? Is it easy to drill through several joints at an angle?

Another way is to cut another hole C and drill from A to C to first to reach B. But I don't want to cut another hole and patch it later.

Any suggestion?

Your A to C option would work, I have never seed a bit that would allow you drill through 2 sets of studs/joists at a time,

A flex bit will not drill at an angle like that, your going to have to open up the ceiling.

First off flex bits are long, like 60" so getting it to run straight on a diagonal is going to be really hard. I would not buy one and then cut it down. Way to expensive for me to do that.

Drilling from A to C and then patching would be a lot easier for me. There is no scale so distances could be a lot farther than indicated.

A flexibit won't work on a heavy angle because it has a starter point that would just walk down the joist bending the bit.

The only thing I can add is be careful drilling blind thru the ceiling.
What is the distance from B to C ?
What I've done is drill from A to C. Send a fish/snake in from A to C and from B to C. The two snakes grab and you pull the B to C snake out. It's not easy but can be done.

Hi, any chance your ceiling is strapped? in other words is you drywall screwed directly to the joists, or is there 3/4 space between it?

It is a good idea to use two snakes. Will try it. I don't think my ceiling is strapped.
