Using Air Drill Underwater

[Poconos]

Something else I just thought of...a Helicoil. For those that don't know it's a coil type insert that gives you the original thread when the hole is damaged. Available at auto stores. Kit comes in different thread sizes with a special size drill, tap, and an insertion tool. My only question would be the coil itself standing up to the water and chemical environment.

I had to do a similar drilling job underwater. I just took my old Makita cordless down in the water and drilled away. Worked fine.
Afterwards I blew the excess water out with a compressor and the drill has worked fine ever since.

I suggest purchasing a light wedge and not worrying about the broken screw.
Google swimming pool light wedge and see what you come up with, there are two styles I've used.

Thanks SoCal.
That should make it pretty easy to visualize.

I'm curious, what do you ride?

I went to Harbor Freight and for 29 bucks purchased a air drill. It worked flawlessly under water with no problems. Bubbles went up out of the way and very little oil. After drilling and pulling the broken piece out with a e-z out I sprayed WD40 inside and out of the drill and as of today it still looks like new !!! Thanks for all the great input and now we all know that a air drill will work just fine in a pool !!

FYI
My pool installer attempted to use the wedge thing on my light and it never did keep it in.

Another happy ending. Glad it worked.
