I was working on getting through the ceiling of my garage to install some eye-bolt lag screws to hang a boxing heavy bag.
I had issues finding the joists which was handled in: Finding ceiling joists overhead
In the process I realized that my drill bits may be insufficient.
I had a 5/16" eye bolt screw to install. First thing I needed to do was expose 5/16" through the ceiling so I can hit the joist. I started with a 5/16" dewalt masonry bit on a dewalt hammer drill. It did nothing. I then switched to a 3/16" bit (not sure what type, probably one of those multi-purpose ones) which worked fine. However, I still needed more space to push my eye screw through so I then switched back to the 5/16" bit to bust through the remaining width. It worked. However, I had to push hard and if i hit the wood, the drill bit turned red at which point I stopped.
I am looking for a good drill bit set to make the pilot holes (as small as possible) and find the joists. After that I need something to expose the wood. Not sure why masonry didn't work initially. Any recommendations on what to use? I assume hammer drill is correct to get through the ceiling. Picture below. Thanks!
