I bore mine with a round file, then I made a nozzle on a drill from sandpaper to smooth the surface a little. Works well, but you have to constantly check inserting and removing the 18650 to check if you removed too much metal, also the hole is not quite round

Very nice!! I mean it's a flashlight so it doesn't need to be perfect just needs to work. Fantastic method.

I have bored several lights. A 6P to 18650 (18.7mm). A Jetbeam RRT0 to 18350. And a Warsun CT9T to 21700. Using an adjustable reamer. Because those reamers are not perfectly cylindrical, but slightly tapered, I reverse the body with every pass. This also prevents things from going sideways.
