Probably not. My typical recessed lighting cans take either a 4-3/8" (110mm) hole or a 6-5/8" (168mm) hole. They work well for that. There is a placement tool that holds the bit "bent" so that you can effectively drill "dead centered" in the timber if you're skilled. No way to prove it to an inspector, obviously. Here's another nifty gadget you might like, along the lines of the broken mirror and head torch. It's called a "wall eye periscope". Works good in ceilings too. It's basically just a mirror with a little LED lamp built in.
